Abstract
This paper examines whether overinvestment can partially explain the negative association between capital investments (long term asset accruals), future profitability and stock returns. Capital investment has a robust negative implication for future profitability. The negative association is stronger when firms have greater investment discretion, i.e., for those firms with higher free cash flow and lower leverage. Moreover, the negative association between investment, future profitability and stock returns is almost exclusively driven by positive discretionary investment, i.e., where overinvestment is more likely to occur, rather than by negative discretionary investment, where overinvestment is much less likely. Evidence in this study provides an underlying explanation for Titman, Wei and Xie (2003)’s notion that managers’ empire building behavior is responsible for the negative association between capital investment and future stock returns. In addition, to the extent that long term asset accruals capture investment intensity, the results here may also provide an alternative interpretation of the long term asset accrual anomaly.

1. Introduction
Capital investments represent a fundamental signal claimed by analysts to be useful in predicting
future profitability and stock returns (Lev and Thiagrajan (1993)). It is also of central importance in
corporate finance research whether firms make sub-optimal investments, and whether market
participants fully understand the implications of managers’ incentives to deviate from optimal
investment levels when they have the latitude to do so. This paper examines whether the overinvestment
can partially explain the negative associations between capital investments, future profitability and
stock returns.
Given the huge amount of capital expenditure by Corporate America each year (e.g, in 2001 the
total capital expenditure reaches 1.3 trillion dollars), it is surprising that so few studies have addressed
the implications of capital investments for future profitability. In the financial statement analysis
literature, Fairfield, Whisenant and Yohn (2003a) document a negative association between growth in
net long term operating assets and one year ahead future return on assets. Richardson, Sloan, Soliman
and Tuna (2003) find a similar association and attribute it to the lower reliability of long term asset
accruals. It is reasonable, though, to believe that growth in long term asset accruals also capture
investment intensity1. Abarbanell and Bushee (1997) show that capital expenditure conveys a negative
signal for future earnings. Thus, there seems to be a negative relation between capital investment and
future profitability. However, there is little evidence as to what factors could explain this negative
association. I study this association from an overinvestment perspective, along with the degree to which
the negative association between investment and future profitability is consistent with the negative
association between investment and future stock returns.
Titman, Wei and Xie (2003a) report that the negative association between capital investments and
future stock returns is stronger in firms with higher free cash flow and lower leverage. They interpret
their evidence as investor under-reaction to the overinvestment behavior by managers with empire
building incentives. However, it is not clear whether it is omitted risk factors or value destroying
discretionary investments that drive their results2. To further unravel the underlying causes, I
investigate how free cash flow and leverage can affect the association between capital investment and
future operating performance. A significant finding would provide an underlying link to support Titman
1 In appendix B, I show these variables are highly correlated with investment opportunities and future realized firm growth. Richardson, Sloan, Soliman and Tuna (2003) also call change in non-current operating assets as “investing” accruals. 2 Some researchers suggest that investment growth may be a factor in asset pricing (Berk, Green and Naik (1999), and Li, Vassalou, and Xing (2001)).

et al’s results and strengthen the overinvestment explanation3.
There are a lot of anecdotes suggesting that managers prefer to expand their companies faster than
they should. For example, prior to its leveraged buyout (LBO) in 1988, RJR Nabisco’s baking unit
devised a plan to revamp and modernize its baking facility at a cost of $2.8 billion. The annual savings
from the modernization would have been only $148 million, providing a pretax return of only 5 percent.
After the LBO, the modernization plan was scaled back4. More generally, the idea that overinvestment
might potentially explain the negative association between investments and future profitability is not
totally new, e.g., Abarbanell and Bushee (1997) conjectured that capital expenditures could be a bad
signal for future earnings if poor performing firms take on excessive projects, though they did not
specifically investigate this issue.
If overinvestment can partially explain the negative association between investment and future
profitability, we would also expect to observe a stronger result in the sample where overinvestment is
more likely to occur. I argue that overinvestment is more likely to occur in the sample where firms make
positive investment than firms that divest, where there may be even under investment. This assumes that
all firms have neutral investment opportunities. To better control investment opportunities, I also
constructs a parsimonious model of discretionary investment—defined as investment not warranted by
investment opportunities—and examines whether the negative associations are stronger in the positive
discretionary investment sample than in the negative discretionary investment sample. Since
overinvestment is more likely present in the former group, I expect to see a stronger association in that
group. Note that other explanations such as a growth effect by Fairfield et al (2003a) or accrual
reliability effect by Richardson et al (2003) make no such predictions. Thus, results would provide
further evidence differentiating the overinvestment explanation from others.
Consistent with my hypotheses, the negative association between investment and future
profitability is stronger in firms with high free cash flow and lower leverages. Applying a parsimonious
model to decompose investment into a non-discretionary portion and a discretionary portion, I find that
the negative association is mostly explained by the positive (discretionary) investment sample.
Next, I examine whether the market can fully incorporate the implications of capital investments for
future profitability. There is a significant negative association between firm investment and future stock
returns and the association is mostly driven by the positive “discretionary” investment sample. An
3 Studying the implication of capital investment for future profitability is also consistent with the view expressed by Penman (1992) that predicting operating performance, as opposed to explaining security returns, should be the central task of financial statement analysis. 4 The Wall Street Journal, Mar. 14, 1989.

investment strategy which goes long in the lowest decile of investment and short in the highest decile of
investment appears to generate persistent hedge returns. The abnormal return remains significant after
controlling firm characteristics and risk factors commonly known to be associated with stock returns.
This study contributes to the extant literatures of agency theory in corporate finance, financial
statement analysis, market efficiency, and investment measurement. First and foremost, it provides
evidence about how agency costs (proxied by free cash flow and leverage) affect the association
between investments and future operating performance: the negative implications of high capital
investments are stronger for firms with high free cash flow and lower leverages. This reinforces
Jensen’s and Titman et al’s notion that empire building incentives drive the negative association
between capital investment and future stock returns. My results are also consistent with recent findings
in Hennessy and Levy (2002) that empire building incentives appear to be the dominant agency issue
distorting firm investment. Second, I empirically validate several commonly used measures of
investment and find that long term asset accruals are good proxies of investment intensity. To the extent
that long term asset accruals capture capital investment intensity, if agency costs can explain the
negative association between investments and future profitability, they could potentially explain the
negative association between long term asset accruals and future profitability. This paper thus provides
a new perspective on the long term asset accruals anomaly that is distinct and perhaps not mutually
exclusive from the reliability conjecture by Richardson et al and growth explanation by Fairfield et al.
Third, I document a strong stock market return anomaly associated with firm investments. The finding
casts doubt on the efficient market hypothesis. The negative association between investments and
future returns is robust to various risk factors and other potentially associated anomalies. The results
may be of interest to financial statement users, such as managers, analysts and creditors who are
interested in understanding the implications of capital investment for firm performance. Last, I validate
several commonly used measures of investment which should benefit future studies.
The remainder of the paper is organized as follows. In section 2, I briefly describe prior research on
investment and stock returns and develop hypotheses. Section 3 discusses the sample and variable
measurements while section 4 presents empirical tests. Section 5 provides concluding remarks.
Appendix A describes variable definitions while Appendix B validates investments proxies.

2. Literature and Hypotheses Development
2.1 Literature
The corporate finance literature is not settled as to whether firms in general tend to over invest or
under invest5. Empirically there is mixed evidence as to how the market responds to capital
investments6. Beneish, Lee and Tarpley (2001) find that the magnitude of capital expenditures is
negatively related to future stock performance. Abarbanell and Bushee (1998) report that
industry-adjusted capital expenditure growth is negatively associated with future returns, a result
contradictory to their hypothesis. Titman et al (2003a) find a similar negative relation and provide
evidence that firm over-investment is responsible for this negative association. Titman et al (2003 b)
compare Japanese keiretsu firms and independent firms and find that in the former groups there is a
negative association between investment and future returns while in the latter the association is positive.
The result is consistent with the idea that keiretsu firms, which have low-cost access to capital, tend to
over invest. Hennessy and Levy (2002) find that empire building is the dominant factor leading firms to
over invest. None of these studies examines the implication of investments for future profitability.
The fundamental analysis literature has documented that various accounting items are predictive of
future earnings (e.g., Penman and Zhang (2002)). Abarbanell and Bushee (1997) examine the
implication of several fundamental signals, including a measure of industry-adjusted growth in capital
expenditures, for future profitability. However, their sample size is much smaller than mine (because of
the requirement of earnings forecast data) and their use of earnings per share as the dependant variable
is subject to critic issue that scale effects influence the results (Easton (1998)).
It is important that research contributes not only to identifying variables that can predict future
profitability, but also to providing economic interpretation of the variables. Current explanations are
mostly conjectures with no supporting evidence. Fairfield, Whisenant and Yohn (2003a) find that two
components of the annual changes in net operating assets--- accruals and long term operating
accruals---are equally strong negative predictors of one-year accounting return on total assets and of
5 In fact, a finding that investment is more sensitive to cash flows is subject to different interpretations: capital rationing and hence under investment (Fazzari et al 1988), over investment (Kaplan and Zingales (1997), Jensen (1986)). Without examining the implication of such investment for future profitability, it is difficult to distinguish the two contradicting theories. 6 In event studies, McConnell and Muscarella (1985) indicate that announcements of increase in planned capital investments are generally associated with significantly positive excess stock returns. Blose and Shieh (1997) and Vogot (1997) find that market reacts to the level of capital investment announcement. Another set of studies examines the valuation effects of actual capital investment using annual returns and the results are mixed. Even studies may be subject to two problems, though. First, firms may self select to announce investment plans. Second, market may misprice the investment in a short window, which is a valid concern. In fact, in the longer window I studies, market seems cannot fully understand the implication of investment on future earnings. Lev and Thiagarajan (1993) find out that industry adjusted capital expenditure growth is positively associated with contemporary returns, while Abarbanell and Bushee (1997) find no such association. Park and Pincus (2003) find incremental information content of capital expenditures beyond unexpected earnings.

stock returns. They conjecture that the accrual anomaly documented by Sloan (1996) is actually a
growth effect caused by diminished returns from investment or conservative accounting. However,
Fairfield et al only examined the implication of growth in net operating assets for one-year-ahead
profitability. While discussing Fairfield, Whisenant and Yohn (2003b), Dichev (2003) argues that the
relation between growth and future profitability has more of a time-series flavor that has not been
documented: this study could be interpreted as filling the impact of capital investment on one to twenty
years ahead performance.
Richardson, Sloan, Soliman and Tuna (2003) find that investors misinterpret the information
contained in various operating and financing accrual items. They argue that different reliabilities
associated with various operating accruals, either current or non-current, should result in different
implications for future earnings and stock returns. While highly convincing, their study furnishes little
evidence on why some accruals are more or less reliable than others. Richardson and Sloan (2003)
construct three measures of net external financing and find that there is a systematic strong and negative
relation between external financing and future stock returns. Based on the finding that future stock
returns are negatively related to changes in operating assets, they suggest that a potential explanation is
firm over-investment in operating assets. However, in the same paper, they also try to add an accrual
manipulation explanation.
There is much empirical evidence that suggests that free cash flow can exacerbate firm
overinvestment (e.g., Kaplan (1989), Blanchard et al (1994)) while debt can mitigate overinvestment
(e.g., Harvey, Lins and Roper (2001)). Results in this study are consistent with above findings.
2.2 Hypotheses Development
I first confirm that high investment intensity leads to decreased future profitability. Although this is
not the focus of this paper, establishing such a relation is necessary for hypotheses to follow. Despite
previous findings that document such an association, Dichev (2003) argues that capital investments
could be positively related to future profitability, e.g., if “capital follows profitability”. Given the result
that investment and future profitability are negatively related, it may be that the relation is explained by
conservative accounting. Penman (2001, 561) argues that conservative accounting could make the
profitability of new investment appear relatively less profitable in earlier years and more profitable in
later years. If conservative accounting is the only underlying force then temporarily dampened return on
assets will reverse sometime in the future years. Penman and Zhang (2002) argue that the profitability
reversal should be more likely to be observed when firm investment growth slows down in the future. If
this is true then capital investment may be a positive portent for long term future profitability. This leads
7
to my first hypothesis, stated as an alternative to reverse:
H1: The negative association between investment and future profitability will not reverse in longer
periods.
If the results are consistent with hypothesis H1, we can infer that there is an economic explanation
for the investment-future profitability association.
While even optimal investment may lead to lower profitability ratios caused by diminished
marginal rate of return, suboptimal investment can further impact profitability. The separation of
management and ownership creates the potential for management to engage in suboptimal activities
including empire building behavior. Managers of firms with high free cash flow can act
opportunistically and indulge in ‘value destroying activities’ and to ‘over invest and misuse the funds’
(Jensen (1986)). Excessive free cash flow enables managers to invest in negative NPV projects after
exhausting positive NPV projects (Blanchard et al (1994), Richardson (2002)). On the other hand, when
firms have a cash short fall, the possibility of over investment is mitigated because the firm is forced to
raise funds through external markets, which provide a monitoring role. If wanton overinvestment results
in lower future profitability, ceteris paribus, we would expect to observe a more negative relation
between capital investment and future profitability for high free cash flow firms. On the other hand,
capital rationing theory7 (Myers and Majluf (1984), Fazzari et al (1988)) predict that high free cash flow
and high cash holdings can benefit a firm by reducing the cost of information asymmetry that places a
wedge between the costs of internal and external capital. Thus high free cash flow enable firms to make
optimal investment with less cost and obtain better future operating performance. I expect the
overinvestment effect dominate the cash rationing effect.
Leverage could potentially mitigate the overinvestment problem. Leverage restricts the use of
internal funds generated by the firm by forcing managers to use cash flow to meet contractual financial
obligations (Jensen (1986), Stulz (1990)). Managers’ empire building incentives may be constrained by
creditors’ legal rights to reorganize or even liquidate the firm in case of default. The debt market also
provides management discipline (Rubin (1990)). Thus, the negative association between investment
and future profitability could reasonably be expected to be weaker in firms with high leverage.
However, debt cannot perfectly solve the problem (Grinblatt and Titman (1998)). Lyandres and
Zhdanov (2003) also emphasized that capital structure cannot by itself induce managers to invest
optimally. High leverage also brings agency cost, e.g., bankruptcy cost. Thus, I expect the effect from
7 Recently there is increasing evidence questioning capital rationing theory (Kaplan and Zingales (1997), Cleary (1999) and Alti (2003)).
8
leverage is of second order and weaker than that from free cash flow. This leads to my main hypothesis,
stated in alternative form:
H2a: The negative association between investment and future profitability will be stronger in firms
with higher free cash flow, ceteris paribus.
H2b: The negative association between investment and future profitability will be weaker in firms
with higher leverage, ceteris paribus.
If overinvestment can partially explain the negative association between investment and future
profitability, we would also expect to observe a stronger result in a sample where overinvestment is
more likely to occur. The negative association probably would disappear in a sample of firm
underinvestment, where the association may be even positive. I argue that overinvestment is more likely
to occur in the sample where firms make positive investment than firms that divest8. This holds if all
firms have equally neutral investment opportunities. To better control investment opportunities, I also
construct a parsimonious model of discretionary investment (defined as investment not warranted by
investment opportunities, for estimation see section 3.2 and appendix B) and examine whether the
negative associations are stronger in the positive discretionary investment sample than in the negative
discretionary investment sample. Since overinvestment is more likely present in the former group,
where the detriment in firm value will manifest in lower future profitability, I expect to see a stronger
negative association in that group.
If negative discretionary investment correctly captures underinvestment, there should be weaker or
even positive association in the negative discretionary investment group. However, if firms generally
over invest, as documented in Hennessy and Levy (2002) and Richardson (2002), then my model that
tries to statistically parse out discretionary and non-discretionary investment may result in some
estimation error, i.e., positive discretionary investment is more likely over investment, but negative
discretionary investment could be either underinvestment, over investment or simply estimation error.
Thus, there is no clear prediction on the sign of the association between investment and future
profitability in the negative discretionary investment group. Thus, I expect:
H3: The negative association between investment and future profitability is stronger in the sample of
positive (discretionary ) investment firms than in the sample of negative(discretionary) investment
firms.
8 Beyond free cash flow and leverages, there may be other agency costs or asymmetric information that affect firms to make suboptimal investment (e.g., Myers and Majluf (1984), Dechow and Sloan (1991)). Although some researchers argue that overinvestment is the dominant effect (Hennessy and Levy (2002) and Richardson (2002)), others provide evidence of underinvestment (Aggarwal et al (1999)).
9
Note that other theories such as accrual manipulation make no such prediction. Thus tests of H3
may to some extent distinguish the overinvestment explanation from the accrual reliability explanation
which claims that long term operating accruals are measured with error, and the growth explanation
which recognizes that when firms make investments, firms would grow in sizes.
The next hypothesis is based on the growing evidence that the market often does not fully
understand the implications of financial statements items (e.g., Sloan (1996), Holthausen and Larker
(1992)). If investors do not understand the negative implications of investment for future earnings, then
a strategy that exploits this information can earn abnormal returns. Titman et al (2003) argue that empire
building managers may have an incentive to put the best spin on their investment opportunities as well
as on their over all business when they make high capital investments, perhaps to justify their action. If
investors fail to recognize the over investment behavior or are fooled by the rosy picture of firm
performance, then the subsequent-period stock returns of firms that made excessive investment may
deteriorate as overinvestment results in lower than expected performance. Moreover, the price
correction might be expected to concentrate around earnings announcements. Based on hypotheses 2
and 3, I also predict the following:
H4a: The negative association between investments and future stock returns will be stronger in
firms with higher free cash flow and lower leverage.
H4b: The negative association between investments and future stock returns will be stronger in
firms of positive (discretionary) investment than in firms of negative (discretionary) investment.
3. Sample, Variable Measurement and Descriptive Statistics
3.1 Sample
Firms’ financial statement data are obtained from the Compustat annual active and research
databases and stock returns data are from the CRSP daily returns files. I use annual Compustat data
instead of quarterly data because firms’ investing activities are not uniform during a year (Callen et al
(1996)). I start my sample from 1962 because from that year the data is available for a substantial
number of firms and also because Compustat data prior to 1962 suffers from serious survivorship bias
(Sloan (1996)). Financial firms (SIC codes 6000-6999) are excluded because their investing, operating
and financing activities may be not clearly demarcated. The full sample consists of 133, 277 firm-year
observations representing 14, 446 firms from 1962 to 2002 to be included in my least restrictive test.
The number of observations in any particular test will vary depending on requirements of the test.

3.2 Investment Measures and Model of Discretionary Investment
In this section I show that long term asset accruals (e.g., change in net PPE or long term asset) and
capital expenditures are both strong proxies of investment intensity. My results in later tests are robust
with respect to the use of each variable. In addition, the question of what is a good measure of
investment intensity is itself of great practical value and surprisingly, no previous studies of the relative
properties of various measures seem to exist.
I begin by choosing a benchmark that relates investment with investment opportunities9. An
investment proxy that best matches investment opportunities may be considered more accurate.
Hayashi (1982) shows that under some conditions, the following equation hold10:
λα
+−+= ]1[1 QaKI (1)
where I is firm investment, K is the beginning-of-period capital stock, α is a parameter linearly
increasing in the cost of adjustment function, Q is the present value of profits from new capital
investment, and λ is some technology shock.
Based on the Hayashi model, it seems that a good measure of investment intensity should be
deflated by either PPE (property, plant and equipment) or total assets. In fact, most researchers proxy
investment with capital expenditure scaled by PPE or total assets (e.g., Kaplan and Zingales (1997),
Hennessy and Levy (2002), Minton and Chrand (1999)).
I apply the following variables to proxy investment opportunities: Tobin’s Q, profitability (ROA)
(Blanchard, Rhee and Summers (1993)), past sales growth (Shin and Stulz (1996)) and value of growth
opportunity (Vgo, Richardson (2002)).
Second, I choose a benchmark for ex post realization of investment. Investment intensity should be
reflected in future growth in sales, earnings and book value. Following an approach similar to Kallpur
and Trombley (1999) and Richardson(2002), I focus on ex post realized sales growth11 , and examine
9 Although I am only trying to evaluate whether one measure is a good proxy for investment, not necessarily optimal investment, it can be shown that under some conditions, a measure that best matches for investment opportunities is more accurate. Assume there are two measures of investment, both measuring the underlying investment intensity with errors:
1I and 2I , where
1*
1 ε++= DII and 2
*2 ε++= DII , where I* is optimal investment and D is the distorted investment resulting from information
cost or agency problem. Assuming 1ε has a smaller variance than that of 2ε and both measurement errors are independent of I, D
and Q, then it is obvious that 1I should be more closely correlated with either Q or (Q and profitability) than 2I does. Further 1I
should fit the model better than 2I in multiple variables regression.
10 Specifically, adjustment costs in investment are linearly homogeneous in investment and capital, so that marginal and average q will equal. 11 I choose not to use growth in book value or earnings as the benchmark. Growth in book value firms may bias in favor of some measures I later choose, e.g., growth in PPE.
11
how different measures of investment are correlated with it. Specifically, I estimate the correlation year
by year and significance for the mean correlation over the entire sample period is assessed by a
Newey-West (1987) t-statistics.
Now I introduce candidates of investment measures. I select several measures that are
representative of what early studies have applied:
Capital expenditure/PPE (e.g., Hennessy and Levy (2002))
(Capital expenditure-Depreciation)/total assets (e.g., Shin and Stulz (1996))
Capital expenditure/Total assets (e.g., Gompers, Ishi and Metrick (2003))
Capital expenditure/Sales (e.g., Anderson and Garcia-Feijoo (2003), Titman et al (2001))
Capital expenditure/Value (e.g., Smith and Watts (1992))
R&D/total assets (e.g. Gaver and Gaver (1993), Hall (1992))
Growth in inventory (e.g., Kashyap, Lamont and Stein (1994))
Growth in capital expenditure (e.g., Lev and Thiagarajan (1993))
Growth in number of employees (Lang, Ofek, and Stulz (1996))
I also add several measures that I contend make sense as well:
Growth in PPE12
Long term asset accruals (Change in long term asset deflated by average total assets)13
Growth in long term asset
Finally, I adopt a measure of a firm’s investment applied by Baber, Janakiraman and Kang (1996),
as the sum of capital expenditure on PPE, acquisitions, and research and development, then deflated by
depreciation expense.
Another measure INV_CS is constructed to measure the cash flows in investing activities:
-(-increase in investment + sale of investment-capital expenditure + Sale of PPE-acquisition), divided
by average total assets14.
Ex ante, we may predict the relative performance among some of these measures of investment
12 The growth measure also takes good care of possible fixed effect that may be present in other measurements. Thomas and Zhang (2002) applied a similar measure to proxy for investment: change in net PPE scaled by total assets. 13 Harrison and Horngren (2003) define investing activities as “Activities that increase or decrease the long term assets available to the business.” “(Investments) increase and decrease long-term assets, such as computers and software, land, buildings, equipment, and investments in other companies. The purchases and sales of these assets are investing activities.” (2003, P548 ). 14 The advantage of this measure is that it is most accurate in reflecting the cash spent in investing activities. A weakness of this measure is that it omits non-cash investing activities. Companies make investments that do not require cash. Non-cash investing activities can be reported in a separate schedule that accompanies the statement of cash flows. Hence, I anticipate this measure is least powerful compared to the growth in long term assets or PPE. A possibly more accurate measure can be derived from statement of cash flows (data311) and reflect how much cash is spent in investing. The disadvantage of this measure is that this measure is only available after 1987.

intensity. For example, capital expenditure/sales(SI ) probably would be a noisier measure than capital
expenditure/PPE (KI ) because
KS
KI
SI /= where the denominator
KS is something like a PPE
turnover ratio which varies across industries and thus introduces some noise into the ratio. Another issue
concerns capital expenditure. Note that it is almost always positive and omits retirement of any PPE.
Focusing on only capital expenditure ignores de-investment from sale of PPE and investment through
acquisition, e.g., where firms liquidate one investment item to finance another investment project. Such
transactions represent potential omitted variables and create potentially an errors-in-variables problem
in prior research. Also, using growth of capital expenditure may be problematic if there is little
expenditure in a prior year. A better measure might be simply the change in PPE divided by lagged PPE.
After all, this is what the model is supposed to relate.
To estimate discretionary and non-discretionary investment, I apply the following rank regression:
ttttt syeardummiemmiesindustrydugrowthSalesROAQINV εβββα ++++++= −−− 131211 _ (2)
These three explanatory variables, Tobin’s Q, profitability and past sales growth, have been shown
to proxy for investment opportunities. Q alone is widely known to be notoriously noisy. Alti (2003)
argues that a substantial part of Q represents the option value of long term growth potential. Since the
option value is not very informative about near term investment plans, Q does not proxy well for short
term investment opportunities. In addition, if the market is unaware of investment opportunities within a
firm, the Q measure cannot sufficiently reflect investment opportunities. Managers may also manipulate
stock prices to justify the expenditure. These issues suggest that other variables be considered as prxies
for investment opportunities. Based on the validation results in appendix A, I choose growth in PPE
(d_PPE) and long term asset accruals (INV_bs) as my measures of investments15 because of their
superior performance and because they are also measures of accruals16.
The fitted value is called to be the non-discretionary component of investment while the residual is
defined to be the discretionary investment. The explanatory power is comparable to various accrual
models with an R square of about 24%. Replacing Q with the value-of-growth-option (vgo) measure
introduced by Richardson (2002) yields almost identical results. In robustness check, I also add past
stock returns as an explanatory variable (Fama (1981)) in the model and obtain very similar results.
15 These measures in spirit are similar to the “new” investment in Richardson (2002) as they are clean of depreciation and amortization, the portion of investment seen as to maintain assets in place. 16 I choose not to combine these measures with R&D or inventory because the former has higher and the latter has lower adjustment costs than investment in PPE, while according to (1) a measure of homogeneous adjustment cost is preferred. In addition, there is little evidence that managers over invest in R&D activities, perhaps because these expenditures are expensed rather than capitalized. Moon (2001) find that the subject of overinvestment may be capital expenditure and not R&D expenditure.

3.3 Return Variables
This section I introduce measures of abnormal stock returns, omitting the t subscript.
Abr = Size adjusted 12month stock return, measured as the realized buy-and-hold stock returns17
from CRSP over the 12 months starting from the end of month four after the end of fiscal year t, minus
the buy-and-hold return on a value weighted portfolio of stocks having similar market capitalization.
The size portfolios are formed by CRSP and are based on size deciles of NYSE and AMEX firms. The
assignment of each stock into size portfolios is based on firm’s market capitalization at the beginning of
the fiscal year in which the return cumulating period starts.
Character = Twelve month stock returns adjusted for firm characteristics. This is another approach
I control for risk. I follow Daniel, Grinblatt, Titman and Wermers (1997) to construct excess returns
relative to benchmarks that are constructed based on firm characteristics (i.e., size, book to market ratio,
and momentum). I form 125 benchmark portfolios based on firm characteristics of size, book to market
ratio and momentum. The portfolios are formed in the following way: Starting with May of fiscal year t,
stocks are sorted into five portfolios based on each firm’s size at the end of fiscal year t-1. The
breakpoints are obtained by sorting NYSE firms into quintiles based on their size measures. The size of
stocks in my sample is then compared against the breakpoints to assign each stock into a size group.
Firms in each size portfolio are further sorted into quintiles based on the t-1 fiscal year end book to
market ratios. Last, firms in each size-bm portfolios are sorted into quintiles based on prior year’s stock
returns ending March of fiscal year t. I choose March in stead of April as the year-end to reduce the
impact of bid-ask bounce and monthly reversals. In each of the 125 portfolios, value weighted returns
are calculated monthly from May of fiscal year t to April of fiscal year t+1. Benchmark portfolios are
rebalanced each year. Each stock’s excess return, called the character-adjusted return, is then calculated
by subtracting the stock’s corresponding portfolio’s return from the stock’s return.
3.4 Free cash flow (FCF) and Leverage (L)
Jensen (1986) defines free cash flow as the portion of cash flow that remains after all positive NPV
projects are taken. However, as Lang, Stulz and Walking (1991) and Gul and Tsui (1998) pointed out,
the literature provides little guidance on the measures of FCF as defined by Jensen (1986). Researchers
often use earnings before interest, taxes and depreciation (EBITDA) or operating cash flow less interest
expense as proxies for free cash flow (e.g., Fenn and Liang 2001).Several proxies are used in the finance
17 Delisting return is applied where available. Where unavailable, I follow Shumway (1997) for NYSE/AMEX stocks and Shumway and Warther (1999) for NASDAQ stocks to correct for delisting bias. I use –0.3 as the last return for NYSE/AMEX stocks and –0.55 as the last return for NASDAQ stocks delisted for performance reasons. If the delisting code is still missing, I use –1. After the delisting and before the end of the 12th month, I assume the proceeds from delisting are reinvested in the value-weighted market
14
literature and I follow these studies to define FCF as operating income before depreciation less interest,
taxes and preferred and common dividends. Such definitions are normalized by either total assets or
total book value of equity in the previous year. I choose to scale by total assets, consistent with Lang et
al (1991), and Gul and Tsui (1998).
As robustness checks, I also apply growth in cash holdings (GrCash) as a second proxy (Harford
(1999)) and Richardson (2002)’s surplus cash measure as a third proxy.
I measure leverage as total liability divided by the sum of total liability and equity capitalization,
similar to Titman et al. I also apply debt ratio as a second proxy for leverage (Lang, Ofek, and Stulz
(1996)).
3.5 Descriptive Statistics
Table 1 provides descriptive statistics for the key variables. The median book to market ratio is
0.593 over my sample period. The median sales growth is 1.598 but the mean is 3.040, thus some firms
have undergone extreme growth. The median and mean accrual is negative, consistent with other
studies and implying cash flow from operations exceeds GAAP operating income on average. From
panel B, investment intensity (d_PPE) is positively correlated with size (log_cap) and profitability
(contemporaneous ROA); thus it seems that firms with low investment intensity are generally less
profitable and smaller in size, consistent with the notion that profitable firms tend to invest more. The
Spearman rank correlations also show that investment measures such as d_PPE , INV_bs and growth in
number of employees (d_employee) are negatively related to one year ahead size adjusted returns (Abr).
Accrual is also significantly related to future abnormal returns, confirming that the accrual anomaly is
present in my sample. Investment measures (d_PPE and INV_bs) are positively correlated with
investment opportunities (lag_q). They are also positively correlated with one year ahead ROA.
However, this correlation does not control for current ROA. Also as expected, these measures of
investment are positively correlated with past stock returns (dt), profitability (ROA) and negatively
correlated with book to market ratio, suggesting the need to control these factors in return analysis.
Except for the correlations between profitability measures in adjacent years, no correlation exceeds
50%, suggesting that multicollinearlity is unlikely to be a serious issue in subsequent regression tests.
4. Empirical Analysis
I present the empirical tests in several steps. In section 4.1 I confirm that a robust negative
association between investment and future profitability, both short term and long term. The evidence
index. Return results are not sensitive to the adjustment of delisting returns.
15
supports the notion that the association is likely to have an economic explanation. In 4.2, I examine how
free cash flow and leverage affect the relation between capital investment and future profitability. In 4.3
I break the sample into positive discretionary investment firms and negative discretionary investment
firms, and examine whether the negative association is mostly driven by the former sample where
overinvestment is more likely to occur. In 4.4 I examine whether investors fully understand the above
relations by looking at stock returns. I also examine whether the mispricing is mostly driven by positive
discretionary investment firms. Since hypothesis 4a is mostly a corroboration of Titman et al, I leave
that test in the end.
4.1 Time series relation between investment and profitability.
Test of Hypothesis 1
When firms increase investment, conservative accounting leads to reported earnings that are lower
than they would have been under liberal accounting. To test whether higher investment will depress
short term profitability but improve long term profitability, I apply the following regressions18:
ntttnt INVROAROA ++ +++= εγβα (3)
where n runs from 1 to 10 years ahead, INV stands for capital investment, ROA is operating income
scaled by average of total assets at the beginning and end of fiscal year19.
Investment will likely inflate future total assets--the denominator of ROA (Fairfield, Whisenant and
Yohn (2003b)). Thus the finding of such a negative correlation could be no more than a mechanical
relation rather than an economic one. However, this denominator effect can not last long in distant years
when capital investments are fully depreciated.
To further mitigate the possibility that the negative association is mechanical, I also examine
earnings deflated by sales (PM):
ntttnt INVPMPM ++ +++= εββα 21 (4)
Panel A of table 2 report regression results applying d_PPE as the investment measure. The
coefficient on current ROA is significant ranging from 0.707 for one year ahead ROA to 0.151 for 10
year ahead. The magnitudes of ROA persistence are similar to those reported in previous studies. The
coefficient on investment is -0.018 for one year ROA. This means that 1% growth in PPE will decrease
one year ROA by about 1.8 basis points. As n increases, the coefficients on current ROA and profit
margin (PM) get smaller, indicating stronger mean reversion of profitability over longer periods. In
addition, the negative coefficients on investment also get weaker. This suggests that the dampening
18 Industry dummies (two digit sic code) are also included in the regressions but not reported for exposition purpose.
16
effect from investment on future earnings becomes less severe in distant years. However, the
coefficients remain significantly negative out to 12 years ahead, then become insignificantly negative
thereafter. This result is inconsistent with conservative accounting which predicts that at some point the
coefficient should turn positive. Thus, conservative accounting is unlikely the only underlying cause for
the negative association20.
On the right hand side of the panel, I examine future earnings deflated by sales and obtain similar
results. In unreported results, I replace all variables by their percentile ranks and get results that are
consistent with panel A.
In panel B of table 2, I use long term asset accruals deflated by total assets (INV_bs) as a measure of
investment and obtain a similarly negative coefficient on investment for the following 10 years’
performance (ROA). The negative coefficients are bigger in magnitude than those in panel A; this might
be caused by the fact that d_PPE is positively skewed while INV_bs is more symmetrically distributed
and hence less affected by extreme values.
The relation documented above is not due to a few extreme years. For example, when regressing
one-year-ahead ROA on d_PPE, the coefficients are negative in 39 of the 40 years.21 I do not examine
tests beyond 20 years because it is not clear whether results will be reliable given the survival bias.
To further highlight the implications of capital investments for future profitability, I present
graphical evidence. I use a two-stage ranking procedure. First, I sort the sample into ten portfolios based
on ranks of current tRNOA 22. Within each decile level of tRNOA , I further sort the observations into
five portfolios based on investment intensity (d_PPE). I then pool all 10 sub-portfolios of each tRNOA
level together into one portfolio. Now I have five portfolios that have substantial variation in investment
intensity but nearly the same level of current profitability ( tRNOA ).The two way sorting ensures that
the observed relation between changes in RNOA over time and investment does not reflect the widely
19 Using operating income before depreciation does not change the results qualitatively. 20 To more directly examine whether there is profit reversal from the conservative accounting effect, I also run the following regressions:
11 +−+ +++= tnttt INVROAROA εγβα where n=2, 5, 10… If there is substantial reversal effect, we would expect to see a positive coefficient on investment. Unreported results show that most coefficients are insignificant. However, I do not assert there is no effect from conservative accounting. 21Unreported results show that other measures of investments, such as growth in number of employees, also implies decreased one year ahead ROA. Fairfield et al (2003b) raise a concern that investment is positively correlated with future total assets, the denominator of ROA. Interestingly I find out that one year ahead earnings by current year’s average total assets is also negatively affected by investments. 22 Applying RNOA rather than ROA provides a robustness check. I repeat the graphical procedure based on ROA and obtain similar patterns.
17
known profitability mean reversion. This control is important as high investment is correlated with
higher current RNOA. In figure 1, I plot the top and bottom quintiles, applying median values of
portfolio RNOA.
Figure 1 shows that, on average, RNOA is higher for high investment firms prior to year 0,
consistent with firm growth and high investment opportunities. However, after year 0, RNOA starts
deteriorating. The low investment firms report lower RNOA than the high investment firms, but by year
0 they report similar levels of RNOA as the high investment group (by construction). After year 0, high
investment firms report persistently lower profitability. In fact low investment firms continue to have
higher ROA than do high investment firms for up to 15 subsequent years. We might predict that ROA
would eventually catch up for high investment firms in later years, e.g., if the low ROA occurred
because not all the high investment expenses (benefits) are properly capitalized (recognized). However,
as shown in figure 1, the ROAs never exceed the ROAs for the low investment firms. This is
inconsistent with conservative accounting explanation which predicts that the two lines should cross
when the hidden reserve from past investment brings higher future profitability. Thus, it seems unlikely
that conservative accounting can solely explain the results23.
The above tests results are consistent with related research in Richardson et al (2003c) that assert
that Fairfield et al (2003a)’s results are not consistent with conservative accounting or diminished
returns to sale. In a related study, Abarbanell and Bushee (1997) also find evidence that the association
between capital expenditure and future earnings does not eventually reverse. Thus, a plethora of
evidence calls for an economic explanation for the association. I investigate whether overinvestment
can provide a partial explanation.
4.2 The Impact of Free cash flow and Leverage
Test of Hypothesis 2a
In panel A of table 3, I examine how the negative coefficients on investment vary with lagged free
cash flow levels, using d_PPE as the measure for investment. I sort the whole sample into five portfolios
based on levels of free cash flow levels in the year prior to investment. Then within each portfolio, I
repeat regression (3) in model 1.
In the left half of panel A, I condition the regression on FCF while on the right side I condition on
growth in cash holdings (GrCash) prior to year of investment.
To examine the effect of free cash flow beyond one year, I also conduct the following regression in
23 In fact, because of the dampening effect of increased investment, the true economic profitability of the high investment group as of year of investment may be higher than that of the lower investment group. That would further bias against not finding the
18
model 2:
522152 tttttt INVROAFROA −− +++= εββα (5)
where FROA is the average ROA from year t+2 to year t+5.
Across both the regressions for one-year-ahead ROA (model 1) and subsequent four year average
ROA (model 2), the coefficient on investment is significantly negative, except in the model 1 result for
the lowest FCF group, where it becomes marginally significant. More important, across both models the
coefficients increase monotonically (becoming more negative) as the levels of FCF rise. For example, in
model 1, the coefficient increases from -0.006 with an insignificant t statistic in the lowest FCF level
group to -0.024 with a significant t statistic in the highest FCF group. In addition, the number of years
when the coefficient is negative ranges from 29 out of 39 years in the lowest FCF group to 37 out of 39
years in the highest FCF group. Results based on GrCash are similar. Unreported rank regressions also
report similar patterns. Thus preliminary tests show that free cash flow is associated with a stronger
relationship between ment and future profitability.
Panel B of table 3 is for long term accruals (INV_bs) as a measure of investment. Again, as the free
cash flow level increases, the negative coefficient on investment increases in absolute magnitude from
-0.002 (t=-0.13) to -0.061 (t=-8.26) in model 1, and from -0.028 (t=-2.60) to -0.060 (t=-6.47) in model
2.
Test of Hypothesis 2b
Panel C of table 3 investigates the effect of leverage in the year prior to investment, using d_PPE as
the measure of investment. On the left side, I report regression results for the five portfolios ranked by
market leverage while the results on the right hand side are for rankings by debt ratio.
Clearly, leverage has an opposite effect to that of free cash flow. In model 1, the negative coefficient
decreases from -0.021to -0.007 as leverage increases. The model 2 regression for future ROA beyond
one-year-ahead exhibits a similar pattern. Using debt ratio as a robustness check yields similar
conclusions.
Panel D of table 3 uses INV_bs to proxy investment. On the left side in the table, we can see that the
coefficient decreases with leverage, although not monotonically; in the highest leverage portfolio, the
coefficient even becomes insignificant. This is consistent with the notion that leverage can mitigate the
negative association between long term asset accruals and future profitability.
Overall, results in table 3 are consistent with H2b. However, one possible concern is that the
conservative effect.
19
negative association between investment and future profitability is nonlinear. Thus the above
documented results are simply a reflection of the positive correlation between free cash flow and
investment levels and negative correlation between leverage and investment level. To address this
concern, I first sort the whole sample into 20 portfolios based on investment intensity. Then with in each
portfolio I further sort by current ROA into 20 portfolios. Within each of the 400 portfolios I rank lag
free cash flow (leverage) level into quintiles. This procedure makes sure that each free cash flow
(leverage) quintiles has similar investment and current ROA distributions. I then repeat the above tests
and obtain similar findings. Figure 2 plots regression slopes of next year ROA on investment (d_PPE) in
the lowest, median and highest quintiles of free cash flow portfolios, while figure 4 plots regressions
slope in each quintiles sorted by leverage. Higher free cash flow level leads to a steeper slope in figure 2,
consistent with H2a. In figure 3, it is interesting to note that the mitigating effect from leverage comes
mostly from highest leverage quintiles. This pattern is also consistent with result in panel C and D of
table 3.
The above tests, how ever, do not provide statistical significance. Thus, I resort to the following
regression to identify the effects from both free cash flow and leverage.

(6) and (7).
What we are interested in are coefficients on the three interactive terms INV*FCF, INV*L and
INV*FCF*L. The first term represent how free cash flow levels affect the negative association between
investment and future profitability. The second term captures effect from leverage. The third term
examines whether leverage can mitigate the overinvestment issue rooted from free cash flow. Based on
H2a and H2b, I expect the first term has a negative coefficient while the other two bear positive
coefficients.
In the regression I also include control variables. I expect the coefficient on FCF to be positive
because free cash flow may itself present a signal of profitability. The implication of leverage is not
clear so I do not make predictions. The effects from interaction term of ROA*FCF and ROA*L are not
clear, either.
Table 4 reports results from regressions (6) and (7) where FCF and L are replaced by their quintile
indexes (e.g., lowest FCF takes value of 0 while highest level of FCF takes value of 4)24. In panel A,
investment is proxied by d_PPE. As expected, coefficient of ROA is positive while that of investment
24 Using dummies or original values yield qualitatively similar results.
20
(INV) is negative across both models. Coefficients on FCF are all significantly positive; suggesting the
need to control this variable as firms with high FCF generally performs better.
Interestingly, the coefficient on leverage (L) is significantly positive in all models. ROA*FCF has
positive coefficient in model 1 but negative coefficient in model 2. In panel B this term has negative
coefficient across both models. One possible explanation is that firms that perform extremely well in the
past (as reflected by this interaction term) cannot keep the momentum and reverse to lower profitability.
The interaction term ROA*L has a significantly negative coefficient (t=-23.93) in model 1 and
(t=-27.82) in model 2. One possible explanation is that these firms have excess cash both from free cash
flow and from external fund, thus providing more resource for managers to engage in negative NPV
projects.
Turning to variables of interest, all coefficients on INV*FCF are significantly negative, consistent
with my prediction. Interestingly, in model 2, the t-statistic (t=9.89) is even more significant than that of
INV (t=-6.09). This suggests that a significant part of the implication of investment for future
profitability can be explained by the free cash flow problem.
The coefficient on INV*L is significantly positive (t=8.11 and t=3.24) in model 1, (t=8.06 and
t=2.69 ) in model 2. The t statistics are relatively smaller compared to INV*FCF. This is expected
because the mitigating effect from leverage is likely secondary. The last interaction term INV*FCF*L
has a significantly positive effect (t=2.82) in model 1 and model 2 (t=2.58). This is evidence that
leverage can mitigate the overinvestment problem that is caused by high free cash flow.
Panel B repeat the regression using long term asset accrual as investment. Results are very similar to
those in panel A. Unreported regressions that apply growth in cash holdings (GrCash) and debt ratios
yields similar results. Thus, results are consistent with H2a and H2b that while free cash flow can
exacerbate the negative association between investment and future profitability, leverage can mitigate
this effect.
4.3 The Stronger Implications in the sample of Positive (Discretionary) Investments versus in
the sample of Negative (Discretionary) Investments.
Test of Hypothesis 3
To test H3, I compare the regression (3) results in the positive (discretionary) investment sample
versus the negative (discretionary) investment sample. H3 predicts that negative association is present
in the former group but not in the latter. Ideally I wish to get a sample of overinvestment; empirically
this is not easy. One parsimonious approach is to classify positive investment firms as overinvestment
sample and other firms as underinvestment. This approach implicitly assumes that all firms have zero
21
investment opportunities. A better control is to classify positive discretionary investment firms as
overinvestment and classify negative discretionary investment firms in the underinvestment sample.
Table 6 reports test of H3. In panel A, I proxy investment by growth in PPE (d_PPE ) while panel B
I apply change in long term asset accruals (INV_bs).
In panel A, the left side reports regression results for the positive (discretionary) investment sample.
All coefficients on investment are significantly negative in predicting up to 5-year-ahead profitability.
For one year ahead regression, the positive investment sample generates a coefficient of -0.019
(t=-10.10) on investment, which is comparable to that obtained in the whole sample. In the positive
discretionary sample the coefficient is -0.016 with a t-statistic of -7.21. In the negative (discretionary)
investment sample, none coefficients are significantly negative. In fact, in the negative discretionary
investment sample some coefficients are even positive (0.022, t=3.02 and 0.018, t=2.64) when
predicting 3 and 4 year ahead performance. This may suggest that there is some underinvestment in this
sample where investment and future profitability is positively correlated. The results provide strong
evidence that the negative association between investment and future profitability is driven exclusively
by the overinvestment sample.
In panel B, we observe similar pattern. The coefficients on investment are significantly negative in
positive (discretionary) investment sample. In contrast, in the negative discretionary investment sample,
no coefficient is significantly negative. In the negative investment sample, the coefficients are
significantly negative only for one and two year ahead ROA regressions. One explanation for these
significant coefficients is that discretion in depreciation recognition drives the result. Another
explanation is that there may be still some overinvestment in the negative investment sample. This latter
explanation is somewhat supported by the fact that there is no significant coefficient on investment in
the negative discretionary investment sample where investment opportunities are better controlled.
The results in both panels strongly support H3 that the negative association between investment and
future profitability is driven by the overinvestment sample. The evidence is inconsistent with the
accrual reliability explanation or a simple growth-in-size explanation.
Sensitivity Tests and Further Analysis
Control for Mean Reversion in ROA
In addition to control for the current profitability, I also try to control previous one and two year’s
profitability as well. The graphical results are similar.
Survivorship
In figure 1, I have presented the different time series of return on net operating assets for high and
22
low investment intensity groups for Year +1 to +15. However, this is based on ex post outcomes and
only firms that survived to the respective year are included in the analysis. Because we do not observe
realizations of RNOA for the non survivors that could not be predicted ex ante, there may be a
survivorship issue. This poses a problem only if the survivorship differs over high and low investment
firms.
The number of firms included in the analysis for each of the years is analyzed. The “survivor” rates
(unreported) for high investment firms in next 10 years were 32.5%, comparable to that of low
discretionary invest firms, 30.0%. Overall there seems to be little survival difference between these two
groups.
Endogenous Investments
Firms may make investment decisions in anticipation of future profitability. However, it is likely
this will biased against my finding that increased (discretionary) investment is negatively correlated
with future profitability. It is hard to imagine a firm would increase (discretionary) investment
anticipating the prospect of the project is poor.
Test in Sub-periods
I repeat tests of H2 and H3 in the following sub-periods: 1962-1971, 1972 to 1981, 1982 to 1991
and 1992 to 2001. Results are all consistent with H2 and H3.
4.4 Stock Returns Analysis In this section I test whether the market is efficient in understanding
the implication of investment information for future profitability25. To do this, I examine the stock
returns performance of buy and sell zero investment portfolios. The portfolio is based on the
cross-sectional distribution of investment intensity. The portfolio is formed as follows: first, each year
from 1962 to 2001, firms are assigned to deciles based on measures of investment intensity. The
hedging portfolio consists of a long position in the lowest investment intensity portfolio and an
offsetting short position in the highest portfolio. Equally weighted size adjusted hedge returns are
calculated over 12 month starting from the end of fourth month after fiscal year end.
Figure 4 shows that the hedge returns can be obtained year after year. The strategy can generate
positive size-adjusted returns in 36 out of 39 years with an average of 12.6%. Results are very strong
even if we apply the character adjusted returns in getting the hedge profits (not shown). One can get
positive hedge returns in 38 out of 39 years26.
25 Unreported Mishkin tests demonstrate that while investment usually leads to lower one-year-ahead profitability, investors actually put positive weight on investment in forming earnings expectation. In addition, the market also fails to understand the implication of discretionary and non-discretionary investments on future profitability. 26 The trading strategy may suffer from a peek-ahead bias because I rank observations in fiscal years which do not necessary end in
23
If investors’ misinterpretation of capital investment is corrected by the subsequent earnings
announcements, either because of the disappointing earnings news of high investment firms or the
improved earnings of firms that cut unnecessary investment, then the abnormal returns will be around
such dates. Figure 5 shows that the hedge returns over the 20 earnings announcement dates generate
persistent profit for 29 of 30 years. The magnitude (5.5%) accounts for nearly half of the annual
abnormal hedge returns. This strengths the mispricing explanation and weakens the risk explanation for
the negative association between investment and future stock returns.
Test of Hypothesis 4b
I repeat the above procedure for the positive discretionary investment (d_PPE) sample. The results
are plotted in figure 6. One can obtain positive hedge size-adjusted returns in 28 out of 33 years. In
contrast, in the negative discretionary investment sample, the same strategy generates positive hedge
returns in only 20 out of 33 years. When applying character-adjusted returns, the contrast is even
starker. The strategy can generate positive character-adjusted returns for 31 out of 33 years in the
positive discretionary investment sample, but only 10 out of 33 years in the negative discretionary
investment sample. This is consistent with the idea that higher investment destroys firm value in the
positive discretionary investment sample where overinvestment is likely, while lower investment
destroys value in the negative discretionary investment sample where underinvestment may be present.
Figure 8 and 9 depicts the above results.
To provide more results in support of H4b, I report in table 7 size-adjusted abnormal returns in each
of the 10 deciles sorted by investment in the positive (discretionary) investment sample versus the
negative (discretionary) investment sample. Again, in panel A I proxy investment by growth in PPE
while in panel B I proxy investment by change in long term asset accruals. The hedge returns in the
sample where INV>0 is 12.8% (t=5.46), similar to the hedge returns based on the whole sample. The
hedge returns is also significantly positive for two-year-ahead (7.9%, t=3.76) but not for the third year
ahead. The hedge returns in the positive discretionary sample is 12% (t=6.20) for one year ahead and
3.9% (t=1.67) for two year ahead. In contrast, in neither of the negative investment sample or the
negative discretionary investment sample can the strategy obtain any significant hedge returns.
Results in panel B are qualitatively similar. One exception is that in the negative discretionary
sample, the hedge return turns significant at 4.3% with a moderate t of 2.20. This is a little bit surprising
December. This is actually is not a problem as I find that an even simpler strategy that does not even require sorting all observations in each year can generate persistent abnormal hedge profits. For example, a simple strategy that long stocks with long term assets growth <-0.2 and short stocks with long term assets growth >0.8 can generate on average a size adjusted hedge return of 15.6% and positive in 36 of 39 years
24
because in this sample there is no negative association between investment and future profitability.
Thus, besides accrual manipulation as one possible explanation27, statistical fluke cannot be ruled out.
Regression Analysis
To further control risk, I apply OLS regression to examine the negative relation between firm
investment and future returns. To control other know anomalies, I need to control firms characters such
as size, beta, book-to-market ratio, Basu (1977)’s E/P anomaly, momentum anomaly (Jegadeesh and
Titman (1993), value/glamour effects(C/P (Desai (2004)) anomaly and the accrual anomaly. Size is
included because several studies find out that size adjusted returns cannot fully control for the size
effect.
Since firms that experience high past returns tend to invest more, it is possible that the documented
effect is related to the long term reversal effect (DeBondt and Thaler (1985). Firms likely would
accelerate investment after experiencing good stock performances. To explore this possibility I, I
construct a variable called dt based on past five year cumulative abnormal (market adjusted).
Regression is conducted as follows: first, each year since 1962 to 2000, I calculate the scaled deciles
rank for investment intensity, size (Cap), beta, E/P ratio, C/P ratio, accruals (Acc), past 5 year abnormal
returns (dt) , and past 1 year returns (Mom, momentum effect). In particular, I rank each observation of
the variable into deciles (0 to 9) each year and divide the deciles number by nine so that each
observation related to the interested variable takes the value ranging from zero to 1. I then estimate the
following separate cross sectional OLS regression for each of the 37 years:

where the dependant variables is size-adjusted abnormal returns. T-statistics are based on
Fama-MacBeth (1973) approach that overcomes bias due to cross-sectional correlation in error terms.
Although the regression approach imposes a linear relationship between returns and the interested
variable deciles, the argument in favor of the regression is its simplicity and ability to list all known
anomaly variables side by side. In additions, some researches argue that the coefficients on the
investment deciles can be interpreted as the abnormal return to a zero-investment strategy in the
respective variable.
Panel A of table 8 reports the results comparing positive discretionary investment sample versus the
27 Francis and Krishnan (1999) show that firm with large negative accruals are more likely to have qualified audit opinions than for high accrual firms. This suggests that earnings management may be more of a problem in lower accrual/investment samples.
25
negative discretionary investment sample. Turning to panel A where I proxy investment by growth in
PPE (d_PPE), in the positive discretionary investment sample, the coefficients of d_PPE are
significantly negative in all regressions. Most anomaly variables have predicted signs on their
coefficients. However, beta is never significant. Size (Cap) is significantly negatively related to one
year ahead abnormal returns in 4 out of 9 models, suggesting the existence of size anomaly.
Book_market has significant positive coefficient, revealing the existence of value-glamour effect. Cash
flow to price (C/P ratio) has a significantly positive coefficient. E/P ratio has a significantly positive
coefficient, but becomes insignificant (t=-0.39) when all other variables are thrown in. Accrual has a
negative coefficient (t=-4.11) but also becomes significant in the presence of other anomaly variables.
This is consistent with Desail et al (2004)’s that find that the coefficient of accrual variable seems to
lose significance in the presence of C/P ratio. However, the accrual anomaly reclaims its significance in
the negative discretionary investment sample. Again, this suggests that earnings management may be
more of an issue in the negative discretionary investment firms that do not perform well. Returning to
positive discretionary investment sample, long term reversal effect (dt) loses significance in the
presence of investment. This finding is consistent with Titman et al, suggesting that long term reversal
effect may be a result of overinvestment in past winners. Last, the momentum effect is significant with
predicted sign. The regression suggests that in the presence of all other anomaly variables, an
investment based strategy could generate an incremental hedge return of 3.5% (t=-2.21).
In contrast, none coefficient of investment in the negative discretionary investment sample is
significantly negative, suggesting the non-existence of investment effect in this sample where
overinvestment is unlikely.
In panel B, the results are very similar to those in panel A. One distinction is that in the negative
discretionary investment sample, there is one significantly negative coefficient on investment when E/P
ratio is included (t=-2.52). This is perhaps not surprising. After controlling for earnings information in
E/P, the investment proxy of change in long term accruals may capture accrual discretion in
depreciation recognition. This conjecture is somewhat confirmed when we include the accrual (ACC)
variable in the regression. In that case, the coefficient on investment actually turns positive.
Overall, results in both panels of table 8 provide additional evidence consistent with that in table 7
and figure 6 to figure 9, strongly supporting H4b28.
28 In unreported results, I control for factor risk and follow Fama and French (1996), I regress character adjusted hedge portfolio returns on the Carhart’s (1997) adaptation of Fama and French (1993) factor models to calculate excess returns. The hedge portfolio that longs the lowest investment deciles and shorts the highest investment deciles has insignificant loadings on all the market, SMB, HML and UMD factors but a significantly positive coefficient. This suggests that the abnormal returns from the zero cost hedge
26
Test of Hypothesis 4a
To corroborate Titman et al’s result, I also regress one-year-ahead character-adjusted returns on
these interaction terms.

The explanatory variables are defined as before, however, I transform variables of ROA and INV
into deciles rank deflated by 9. Some researches argue that the coefficients on the investment deciles
can be interpreted as the abnormal return to a zero-investment strategy in the respective variable. The
usage of character adjusted returns controls for firm characters that have been shown to be related to
stock returns. Following Titman et al, I eliminate top and bottom 1.5% extreme values of character
adjusted returns to reduce the impact of outliers. Table 5 reports results based on Fama-McBeth
approach. Coefficient on ROA is significantly positive, suggesting the well know post earnings
announcement drift anomaly (PEAD). INV is negatively correlated with future stock returns. The
significance on FCF is surprising, this could be a reflection that FCF is correlated with earnings, and
PEAD lasts for more than one year. Turning to variable of interest, INV*FCF bears a significantly
negative coefficient (t=-2.02) applying d_PPE as investment and (t=-1.73) applying long term asset
accruals. This is consistent with Titman et al’s findings. I also only find marginally positive coefficient
for INV*L applying INV_bs as investment and no significant coefficient applying d_PPE. This is not
surprising as the effect from leverage is considerably weaker than that from free cash flows. The
interaction term INV*FCF*L is not significant. Overall, results are consistent with the notion that
overinvestment may partially explain the negative association between capital investments and future
stock returns.
5. Conclusion
This paper represents the first attempt to examine whether the overinvestment incentives identified
by Jensen (1986) can partially explain the negative association between capital investment (long term
asset accruals) and future profitability. My results show that this association is indeed exacerbated when
firms have high free cash flow and low leverage, consistent with management empire building
incentives. Further analysis reveals that it is the positive discretionary investment sample that drives the
negative association. The negative association between investment and future profitability is robust to
scaling of investment and conservative accounting effects. The negative association between
portfolio are not explainable by these risk factors.
27
investment and future stock returns is moreover robust to character-based and/or factor based risk
adjustments.
Besides providing an underlying link supporting Titman et al (2003a), the findings in this paper
open a window for reexamination of the long term accrual effect and perhaps the accrual anomaly as
well. While discretionary accruals are often interpreted as a proxy for earnings manipulation, it is
interesting to note that explanatory variables that are applied in various versions of Jone’s models, such
as growth in sales and PPE/total assets, might also proxy for investment opportunities29. Thus it is
possible that discretionary accruals actually capture discretionary investment. In addition, growth in
inventory, which is mainly responsible for the accrual anomaly, is in fact a measure of investment
intensity (Kashyap et al (1994)). Future study in this area seems warranted.
There are certainly other potential explanations for the negative associations between investment,
future profitability and stock returns beside those emphasized here. In fact, accrual manipulation and
overinvestment are more likely complementary rather than mutually exclusive explanations. Managers
may portray a rosy picture of firm performance to justify empire building investment30. Expenditures
that should be expensed may be capitalized, creating unreliable accruals. On the other hand, some
researchers argue that long-term assets and PPE are subject to less earnings management (e.g., Beneish
(1998) argues that manage earnings via depreciation is either transparent or economically impossible;
Sloan (1996) argues that long term accruals associated with investment cannot be easily manipulated.).
Further research in this field is necessary to clarify these issues.
One way to do this would be to examine how corporate governance and compensation structures
affect the negative association between investment and future profitability. For example, if the
existence of independent financial experts on the audit committee significantly mitigates the
association, the association is more likely due to earnings management.
29 Shin and Stulz (1996) uses growth in sales to proxy investment opportunity. Skinner (1993) applies PPE/firm value to proxy investment opportunity. 30 Christie and Zimmerman (1994) suggest that non-value-maximizing managers are more likely to mask non-optimal expenditures by accounting manipulation.

Appendix B: Analysis of Alternative Measures of Investment Intensity
In this appendix I compare the construct validity of several measures of investment intensities. A
more accurate measure of investment should be more closely related to investment opportunities. I back
test the correlation using data from 1962 to 2002. The sample covers 208,935 firm years from
Compustat. This approach faces the problem of using ex post data to measure ex ante constructs. To
help mitigate this problem, I use a portfolio approach. The assumption is that ex post shocks affecting
future realization and affected by past investment opportunities within each portfolio will be
uncorrelated.
The ex ante investment opportunities are proxied by (i) Q , (ii) value of growth opportunities (Vgo)
constructed by Richardson (2002), (iii) Past sales growth (Growth_sale) and (iv) profitability (ROA),
all measured in the year before investment. The ex post measures are (i) growth in future sales growth. It
is measured as the geometric mean of five-year growth in sales (data12), denoted SG5.

investment opportunity and future realization. The median firm from 1962 to 2002 had a Q ratio of
1.29, Vgo of 0.28, d_ppe of 0.07 and future sales growth of 1.60. There is considerable variation among
all my measures of investment, suggesting that they make both positive investment and de-invest.
Panel B: Correlation across Measures of Investments
36
Panel B reports correlations among different measures of investment. Given that they are all purport
to measure the same underlying activities, it is not surprising to see strong positive correlations. It is
interesting to note that my measures (d_ppe and d_LA) on average have higher correlations with other
variables. R&D is negatively correlated with investment cash flows and capital expenditure, suggesting
that it might not be a good indicator of overall firm investment.
Researchers often scale long term asset accruals by average total assets in stead of total long term
asset. d_PPE and d_LA are highly correlated with long term asset accruals scaled by average total
assets, with Spearman correlation of 0.78 and 0.95 respectively. This suggests that d_PPE and d_LA are
very well proxies of long term asset accruals.
Panel C: Correlations across Measures of Growth Opportunities
Panel C reports the correlations between four measures of investment opportunities. They are all
significantly correlated because they relate to a similar construct. VGO is negatively correlated with
ROA because of the way VGO is constructed, see Richardson (2002).

Panel D: Mean Annual Portfolio Spearman Correlations between Investment Measures and
Investment Opportunities
In panel D, I report the mean annual correlations between each investment measure and the ex ante
investment opportunities measure as well as future sales growth. The reported correlations are means of
rank correlations in 40 annual portfolios. Each variable is ranked into 20 portfolios based on yearly
distributions of investment opportunities. The reported correlations are the mean Spearman correlations
between portfolio number and median values of investment measures. This is following Richardson
(2002) and Kallapur and Trombley (1999). I highlight in bold letter the four highest correlations in each
row. The important point is that my measures, growth in long term asset (d_LA) and growth in PPE
(d_PPE) perform well. It is also obvious that measures used in earlier studies (growth in capital
expenditure, capital expenditure over sales) do not perform well. In fact, their performance is dominated
by growth in inventory, an investment measure used by Kashyap, Lamont and Stein (1994). capex_PPE
works better than capex_ta, both of which are commonly used in economics research. R&D over total
assets again does not stand out, suggesting that R&D activity may be more representative of operating
activities hoping to find investment opportunities than representative of capital investment. Baber et al’s
measure performs well; I choose not to apply this measure in presenting the results because this measure
may be more sensitive to how accountants book the depreciation.
Panel E: R-squared from Regressing Investment Measures on Q, Past Sales Growth and
Profitability.

Researchers concern that Q measure is a noisy measure of investment. It is well known that the Q
measure suffers from serious measurement error problem. People contend that higher profitability can
signal greater project quality or investment opportunities (Fazzari et al (1988), Cleary (1999) and Alti
(2003)). I also follow earlier studies (Kaplan and Zingales (1997), I also include growth in sales in the
past five years. Finally, replacing Q with Richardson 2002’s measure of growth opportunities does not
materially change the results. Following previous studies and also based on empirical findings, I include
these proxies for investment opportunities at the beginning of the year. In Panel E I report the R-square
of the regression of each investment measures on three variables that are claimed to be correlated with
investment opportunities. In the regression all variables are replaced by their ranks so the comparison of
R-squares might be meaningful.
Over all, result suggests that measures d_PPE and INV_bs are more closely related to investment
opportunities than other widely used variables, e.g., Capex_sale.
Panel F: Getting Discretionary Investments using rank regressions.
The following table reports rank regressions of investment on proxies of investment opportunities
and 2-digit sic industry dummies and year dummies. The residuals (from models without lag_abr) are
estimated discretionary investments applied in later tests.
