Using a well-established methodology to measure aggregate insider trading, this exploratory study
examines the relation between future stock market returns and aggregate trading by corporate insiders (in
academy commonly referred to as insider trading and directors’ dealings). Analyzing a unique data set of
more than 1.3 million filings of individual directors’ transactions in 16,893 US, European, and Asian
firms from 2003 to 2017, we provide novel results for a multitude of countries which had not been
thematized before. We find that the null-hypothesis (i.e., aggregate trading by directors is not related to
future stock market returns and corporate insiders cannot forecast economy-wide trends) cannot
conclusively be rejected for all countries in the sample. Only aggregate directors’ dealings in the US,
Luxembourg, Switzerland, Poland, Asia-combined, China, India, and the Philippines is coherently
positively associated with future market returns. Implications and further research opportunities are
discussed.

1. Introduction
It is well established that corporate insiders profitably trade shares in
their own firms on US (Finnerty, 1976a; Jaffe, 1974; Lakonishok & Lee,
2001; Seyhun, 1986), European (Aussenegg, Jelic, & Ranzi, 2016;
Fidrmuc, Goergen, & Renneboog, 2006), and Asian (Bris, 2005; Jaggi &
Tsui, 2007) markets. It can be assumed that insiders trade for one of three
distinct reasons: randomness, firm-specific factors, or market-wide
factors. Based on extant academic evidence in multiple geographic
regions, and the fact that outside investors trade profitably on publicly
available insider transaction filings (e.g., Altana Wealth Ltd, 2018;
Sabrient Systems LLC, 2018), the information advantage hypothesis can
be accepted. Accordingly, randomness-based trades can be ruled out.
What remains is the conundrum as to whether insiders trade on firm-
specific or economy-wide superior information.
If insiders base their trades predominantly on macroeconomic private
intelligence, it is likely that a majority of insiders possess similar
information and collectively trades in a particular direction. If this is
indeed the case, aggregate insider transactions should be able to forecast
future market returns as the market takes into account economy-wide
changes after they will have substantialized, and a positive correlation
between aggregate insider transactions and future market returns should
become observable.
If insiders do not collectively base their trades on expectations of
market-wide developments, aggregate insider trading will not be
statistically significantly associated with future stock market returns, and

insiders are more likely to trade for private firm-specific cash flow news.
Most evidence on insider trading is on the information content of
individual firm-level transactions. Extent studies on the relation between
aggregate insider trading and future market returns almost exclusively
examined US SEC-regulated insider trades in the 1970s and 1980s
(Chowdhury, Howe, & Lin, 1993; Lakonishok & Lee, 2001; Seyhun,
1988, 1992), and can thus be considered outdated. The scarce evidence on
other, less developed, markets is limited in its geographical scope (Zhu,
Wang, & Yang, 2014). Aggregate insider trading and its relation to stock
market returns with a particular focus on non-US markets thus merits
further analysis. Accordingly, the aim of this exploratory study is to
update and extend findings on the relation between aggregate insider
trading and future market returns. The paper contributes to the literature in
the following ways. This is the first study to examine aggregate insider
trading and its predictive power for future market returns in a multitude of
European and Asian countries. It also updates prior insights on the US
market. Thereby it adds substance to the discussion as to whether insiders
possess superior knowledge pertaining to firm- or economy-specific
developments.
By analyzing a unique data set of more than 1.3 million individual
insider transactions in 16,893 US, European, and Asian firms from 2003
to 2017, we find that outsiders cannot always easily distinguish whether
executives, directors, and other corporate insiders trade on superior firm-
specific or market-wide information. Aggregate insider trading can only
coherently predict future market returns in the US, Luxembourg,
Switzerland, Poland, Asia-combined, China, India, and the Philippines.
Insiders in these countries appear to trade on economy-wide expectations.
In Europe-combined, Germany, France, the United Kingdom, Italy,
2 Aggregate Trading by Insiders and Future Market Returns in the US, Europe, and Asia
Russia, Spain, the Netherlands, Sweden, Belgium, Austria, Norway,
Ireland, Denmark, Finland, Romania, Greece, Cyprus, Turkey, Hong
Kong, Korea, Australia, New Zealand, Malaysia, Singapore, and Thailand
aggregate insider trading does not predict a coherently positive correlation
with future stock market returns. Insiders in these countries are more
likely to trade on future firm-specific cash flow news. Our findings imply
that outside investors can use publicly available data to inform passive
investment strategies’ decision-making for particular countries. This study
covers multiple insider sentiment aggregation horizons (during which
insiders trade) as well as multiple long-term forecast horizons (during
which future returns substantiate) and discusses potential reasons as to
why results are heterogeneous across countries.
The paper is structured as follows. Section II provides a literature review
and builds up the main hypothesis. Data and methodology used are
presented in Sections III and IV, respectively. Empirical findings are
reported in Section V, followed by a discussion in Section VI, and
conclusions and future remarks in Section VII.
2. Literature Review
Insider trading is defined as corporate insiders (e.g., executives,
directors, and significant stockholders) buying or selling financial
instruments in their own firms’ stocks. In most jurisdictions, it is generally
considered legal, as long as the trades are not based on material non-
public information. Corporate insiders in the EU, the US, and in multiple
Asian countries may trade legally in their own securities, but are obligated
to report their trades to the relevant market authority. Assuming that
insiders are rational economic agents who intend to maximize their private
wealth, they do not trade randomly, but on superior information or
knowledge of future cash flows in their firms. Their advanced insights
into firms’ opportunities, threats, and the competitive position in the
market allow them to perceive mispricings relative to current share prices
and changes in cash flows (Piotroski & Roulstone, 2005). When corporate
insiders deem current prices too low, they are likely to be net buyers.
When prices seem too high, they will turn into net sellers.
Firm-specific insights may stem from multiple sources. Previous
research claimed that insiders may base their transactions on their
interpretation of financial information which may differ from analysts’
expectations, knowledge of internal forecasts, a better understanding of
the company’s competitive position in the market relative to competitors,
or simply a better ‘gut feeling’ (Cohen, Malloy, & Pomorski, 2012;
Finnerty, 1976b; Pope, Morris, & Peel, 1990). Moreover, insiders benefit
from firm-specific cash flow considerations related to proposed mergers
(Keown & Pinkerton, 1981), new issue announcements (Karpoff & Lee,
1991), dividend announcements (John & Lang, 1991), expected R&D
outcomes (Aboody & Lev, 2000; Coff & Lee, 2003), and imminent
breakthrough developments and product announcements (Ahuja, Coff, &
Lee, 2005; Coff, 2010). Additionally, there are studies revealing evidence
for firm-level market timing abilities (Friederich, Gregory, Matatko, &
Tonks, 2002) and for insiders contributing to general market price
discovery efficiency on insider trading days (Aktas, de Bodt, & Van
Oppens, 2008).
Overall, corporate insiders are motivated and incentivized to buy
shares in anticipation of positive firm-specific news and vice versa. They
are able to gather, decipher, and trade on firm-specific information. The
greater the information asymmetries vis-à-vis outsiders, the greater the
ability of insiders to exploit private information.
Corporate insiders do not only seem to be able to perceive mispricing
in their own firms and anticipate changes in their firms’ cash flows based
on firm-specific information. Instead, directors, executives, and other
insiders might also base trades on their sentiment towards future
economy-wide developments and the respective impact on corporate cash
flows. Insiders across firms in a given country may develop similar
expectations of trends in macroeconomic factors and future stock market
corrections. These anticipations are likely to be reflected by aggregate
insider trading, i.e., the net summation of corporate insiders’ transactions
across publicly traded firms. As other investors start perceiving changes in
economy-wide indicators as well, they will alter their valuations and drive
share prices across firms accordingly, resulting in respective market
returns (Seyhun, 1992). Consequently, insider sentiment in terms of
aggregate insider trading would predict future stock market returns.
The connection between aggregate insider trading and its
ability to forecast future market returns is likely to stem from three
different sources. Insiders’ ability to perceive unanticipated changes in
macroeconomic trends earlier, their ability to observe such changes more
effectively, and their ability to detect systematic market misvaluations
induce a “macro information advantage” relative to other investors
(Seyhun, 1988; Zhu et al., 2014).
First, insiders at the operational forefront and those well-connected to
insiders at other firms have preferential access to information pertaining
to, e.g., price movements, capacity utilization, and restructurings. This
allows them to perceive economic trends, e.g., inflation, aggregate
demand, a country’s Gross Domestic Product (GDP), and unemployment
rates earlier than the general public, which can only access trade and
commercial statistics later. Once other market participants will have
picked up on changes in economy-wide activities as well, stock prices
collectively rise (Jiang & Zaman, 2010).
Second, corporate insiders also tend to possess high levels of
education (see Barker & Mueller, 2002), an improved understanding of
their firms and the industry, and experience as to how macroeconomic
trends affect their firms’ cash flows. Consider the following example.
Based on executives’ knowledge of suppliers’ price alterations and
industry structures, they might anticipate shifts in demand for
intermediate goods. Accordingly, these insiders might sense changes in
demand for a range of final goods earlier than outside investors and thus
deduce economy-wide trends (as the market value of final goods
determines a country’s GDP). If such economy-wide trends pertain to a
substantial proportion of the total firm population, corporate insiders
across firms would perceive market-wide mispricings and trade in the
same direction. Later on, outside investors might gain access to similar
trade information, realize that firms’ current prices deviate from their fair
values, and buy or sell shares accordingly. In other words, current
aggregate insider sentiment may predict future stock market returns and a
temporal connection between the two should be observable.
Third, markets may overheat (consider e.g., quantitative easing) or be
overly bearish (consider e.g., market crashes/dips and overreactions) due
to exogenous shocks and irrational behavior. Such systematic overpricing
and underpricing may be perceived by corporate insiders who then trade
their own firms’ shares accordingly. If multiple firms’ stocks suffer from a
particular mispricing, insiders collectively capitalize on the prices, and
their transactions tend to appear in selling or buying waves (Zhu et al.,
3 Aggregate Trading by Insiders and Future Market Returns in the US, Europe, and Asia
2014). For instance, examining the stock market crash of October 1987,
Seyhun (1990) presented evidence that corporate insiders did not predict
the market crash, but correctly predicted the strongly positive market
returns during the subsequent recovery. There was no increased insider
sales activity before the crash, but a record number of net aggregate
purchases following the crash, which indicates that collectively insiders
correctly identified systematic mispricing in the market induced by
outside investors’ previous overreaction. More recently, analyzing insider
sentiment around the 2008 financial crisis indicated that corporate insiders
were able to perceive a general price bubble and traded accordingly, prior
to the crisis’ peak. In February 2018, a slump of more than 8 percent in
the S&P 500 and the Dow Jones Industrial Average was predicted by
insiders, as a high aggregate volume of sales transactions prior to the drop
indicated a strongly bullish sentiment (Altana Wealth Ltd, 2018).
2.1. Empirical evidence of aggregate insider trading
There is some empirical evidence corroborating the theoretical
grounding laid out above. Seyhun (1988) was the first to establish that
aggregate corporate insider sales and purchases can be linked with future
stock market returns. Analyzing US insider trades from 1975 to 1981, the
results suggest that aggregate insider trading conveys information
pertaining to future changes in economy-wide trends not already factored
into current stock prices. The study documented a significantly positive
relation between monthly aggregate insider trading and market returns
during the following two months. Specifically, one standard deviation
change in the standardized aggregate net number of executives’
transaction predicted up to 1.7 percent change in future excess market
returns. Moreover, the author showed that insiders’ transactions in firms
of greater market value carry a greater predictive value for future market
returns. Hence, such insiders seem more informed of future
macroeconomic trends. Insiders in firms with greater market risk trade
more on economy-wide expectations and information (Seyhun, 1988).
Analyzing US insider sentiment 1975 to 1989, Seyhun (1992)
documented a strong relationship between aggregate insider trading and
future stock returns in excess of one-month Treasury Bills. This seminal
paper revealed that using long-term aggregation horizons to predict long-
term forecast horizons is associated with particularly strong prediction
abilities. According to the findings, up to 60 percent of future one-year
market returns’ variation could be predicted by twelve-month aggregate
net numbers of transactions. Moreover, Seyhun (1992) found that
aggregate insider trading is positively associated with future growth rates
of the Index of Industrial Production and the Gross National Product,
which suggests that insiders possess some forecasting ability concerning
economy-wide activity. However, including future real activity as an
additional explanatory variable of future returns does not render aggregate
insider trading insignificant. Insider sentiment does thus retain an
explanatory meaning for market returns in its own right.
There is some discord in the literature as to whether insiders merely
follow a contrarian investment strategy or actually trade on superior
information. Chowdhury et al.’s (1993) results contradict Seyhun’s (1988,
1992) earlier findings. Analyzing the short-term relation between
aggregate insider transactions in 1,361 US firms from 1975 to 1986 and
market returns, the authors documented that the predictive power of
aggregate insider transactions is existent but actually slight. Instead,
Chowdhury et al. (1993) found strong evidence for a reverse relationship.
Current market returns predict aggregate insider trading, i.e., high stock
market returns cause insiders to sell off stock and vice versa.
Examining US insider transactions from 1976 to 1995, Lakonishok
and Lee (2001) reported further findings in support of aggregate insider
transactions’ predictive power for future market returns. Controlling for
contrarian insider investing, they found that aggregate insider trading can
predict future market returns. For instance, Lakonishok and Lee (2001)
reported an 11 percent gap in future twelve-month returns between
months of very low versus very high net purchasing activities. Moreover,
the authors showed that managers’ aggregate trading is associated with
greater predictive power for future stock market returns than large
shareholders’ one. Longer sentiment aggregation horizons and forecast
horizons were both associated with greater predictive powers.
Jiang & Zaman (2010) analyzed the relation between aggregate insider
trading and future market returns using a novel returns model, which
allowed them to distinguish between future market return components
related to insiders’ superior knowledge of economy-wide factors and
those related to contrarian investing. They demonstrated that insiders’
predictive skills are due to their ability to forecast unexpected future cash-
flow news which can be related to changes in economy-wide activity.
Examining US data from 1975 to 2000, they do not find evidence
suggesting that insiders act as contrarian investors.
More recently, Marin & Olivier (2008) presented additional anecdotal
evidence indicating that aggregate insider trading predicts substantial
future market crashes and jumps.
The only study on insider sentiment and future market returns in
emerging markets (Zhu et al., 2014) established that in China, aggregate
insider trading also predicts future market returns, even to a greater extent
than insider trading in the US. Analyzing 5,553 insider transactions
between 2007 and 2011, the authors found that insider trading can forecast
up to 72.7 percent of variation in future market returns. Furthermore, Zhu
et al. (2014) showed that higher levels of operational involvement and
hierarchy are associated with greater degrees of predictive power, which
they attribute to more pronounced abilities to forecast macroeconomic
developments and observe systematic market misvaluation relative to
other insiders. The authors also provided evidence that state-owned
companies’ insiders exhibit lower abilities to predict future market returns
than insiders in firms with different corporate governance structures.
Overall, conceptual and empirical evidence suggests that insiders can
effectively observe macroeconomic developments and systematic
misvaluation in the market and trade own firm shares accordingly.
Aggregate insider trading is a substantial leading predictor of future stock
market returns. Studies show that aggregated insider trading does not
constitute a simple contrarian strategy, but that transactions carry
predictive power. Additionally, there are some groups of insiders which
are associated with greater predictive power than others. Given the
prevalence of varied types of insiders, firm sizes and risk characteristics,
and market dynamics across countries, it is reasonable to assume the
existence of substantial differences in the predictive power of aggregate
insider trading across countries.
2.2. Trades based on firm-specific vs. economy-wide information
Aggregate insider trading’s predictive ability is not a simple
summation of insiders’ trades on firm-specific information. Assume
prevalence of firm-specific news to be near-normally distributed, with
4 Aggregate Trading by Insiders and Future Market Returns in the US, Europe, and Asia
positive and negative information at each respective tail of the
distribution. Assume further that firm-specific news are independent of
changes in economy-wide activity. If insiders trade exclusively on firm-
specific knowledge, their transactions’ directions, amounts, and volumes
are likely to net out in aggregate. In a given sentiment aggregation
horizon, transactions of insiders anticipating favorable news and thus
buying shares would be cancelled out by those based on unfavorable
expected cash-flow news inducing insiders to sell shares. Accordingly, no
distinct insider sentiment would be deducible, and current aggregate
insider sentiment should not predict future market returns. Instead, it
would appear that transactions are predominantly based on firm-specific
information. However, if a large proportion of corporate insiders buy or
sell shares in concurrent waves, trades would appear to be based on
mutually shared information about future market-wide activities (cf.,
Seyhun, 1988; Zhu et al., 2014). It is reasonable to assume that in some
countries, information asymmetries provide for great opportunities for
insiders to exploit firm-specific information and market structures do not
allow insiders to perceive macroeconomic developments. In such
countries, it would be expected that no distinct insider sentiment can
established and no connection between aggregate insider trading and
future stock market returns can be observed. The same logic also applies
vice versa.
In summary, corporate insiders possess superior information or skills
allowing them to perceive mispricings in their firms’ stock, and trade on it
accordingly. Perceived mispricing may originate from two sources:
economy-wide and firm-specific expectations of changes in cash flow.
Divergent insider, firm, and market characteristics across countries may
cause differences in insiders’ ability to trade on firm-specific or
macroeconomic information. We thus hypothesize that aggregate insider
trading can predict future stock market returns in multiple European and
Asian countries and the US. With respect to varying insider forecast
abilities we do not expect homogenous results across countries.
3. Data Sources and Sample Characteristics
Daily-closing indices prices to compute returns as well as exchange
rates to convert all monetary values into US Dollars were downloaded
from Bloomberg. For each country, the most common index featuring the
most liquid stocks and most highly capitalized firms was chosen to
represent the particular country’s stock market returns*. To analyze the
relationship between aggregate Europe-combined and Asia-combined
insider trading and stock market returns, the EURO STOXX 50 and MSCI
AC Asia ex Japan indices are used.
Corporate insider trading data is obtained from a unique data set on
which no prior published research has been carried out. The data set was
constructed by Altana Wealth Limited on the basis of 2iQ Research
GmbH filings and Bloomberg L.P. information. The sample includes all
insider trades in listed firms with a market capitalization of at least
USD250 million at the time of filing domiciled in the US, 21 European,
* Due to space constraints, the utilized stock market indices are not shown here. A
list of indices used for each country can be obtained from the authors upon request.
and 10 Asian countries from 2003 to 2017. The sample consists of three
regional sets of transactions on US, European, and Asian exchanges. Both
cash-market and derivative transactions were included in this study.
Transactions arising from the award of stock-based executive
remuneration are excluded, as these transactions are not grounded in
executives’ perceptions of firm-specific or economy-wide mispricings.
Also, transactions featuring missing data were omitted from the sample.
Table 1 Appendix A
In Table I, overall sample characteristics, the number of firms and
unaggregated filings present in the sample, the aggregate purchase and
sales volumes, and the aggregate numbers of shares bought and sold, can
be observed. The table shows the top-level statistics per country as well as
for Europe-combined and Asia-combined. Firms and their associated
insider transactions were assigned to a country based on a firm’s country
of domicile as listed on Standard & Poor’s Compustat database. This
mapping was chosen to reflect the country in which most corporate
insiders are likely to reside, consume media, and interact with members in
their network, which accumulates into their expectations formation
process vis-à-vis macroeconomic trends. The US sub-sample contains all
insider trades on US exchanges and in firms listed abroad but domiciled in
the US. The Asia-combined and Europe-combined sub-samples are based
on all insider transactions filed on Asian and European exchanges,
respectively†. Table I shows that the overall sample of insider trades in the
time period ranging from 2003 to 2017 contains a total of 1,349,265
insider transactions in 6,093 US, 4,233 European, and 6,567 Asian firms.
The total number of shares assessed in the overall sample amounts to
5.429 trillion shares traded by corporate insiders. Unsurprisingly,
countries featuring a lower number of firms in which insider trades were
conducted are also associated with lower total volumes and amounts of
shares in the sample. However, a country’s economy’s size, in terms of
GDP, is not necessarily correlated with lower numbers of firms, filings, or
shares in the overall sample. The number of firms and filings is also an
indication as to the introduction date of insider trading regulations and the
prevalence of insider trading in the respective country.
As expected, the net total number of shares (i.e., the sum of all shares
bought minus the sum of all shares sold), as well as the net total volume
(i.e., the volume of all buy transactions minus the volume of all sales
transactions per country in the sample) tend to be negative for most
countries. This means that insiders sell more shares than they buy, which
is consistent with previous studies (Aboody & Lev, 2000), and mainly due
to executives selling shares they had previously been awarded with as a
part of their remuneration packages (i.e., liquidity needs).
4. Methodology
The study’s methodology is adapted from the established literature on
aggregate insider trading (Seyhun, 1988, 1992). In order to achieve the

5 Aggregate Trading by Insiders and Future Market Returns in the US, Europe, and Asia
goal of this paper, to demonstrate the empirical relationship between
aggregate insider trading and future stock market returns in multiple
countries, twelve economic models per country or region were established
as follows.
For each country or region, we use three different measures to
operationalize the independent variable, aggregate insider sentiment;
standardized aggregate net number of transactions ( ), standardized
aggregate net number of shares ( ), and standardized aggregate net
volume of shares ( ). First, for each day and firm all individual
insider transactions are converted into daily events as follows
∑
∑
∑
∑
{
where and are the net event number of shares and
volume of shares for firm on day , respectively, and are
numbers of shares purchased and sold in each individual transaction , and
and are the volumes of shares purchased and sold,
accordingly. The number of transactions in a given firm on a given day is
denoted . If the daily-firm event’s net volume is positive, the event
transaction’s direction, , equals and vice versa.
Second, , , and are summed per firm and month:
∑
∑
∑
where denotes the number of days in a given month, and , ,
and are the monthly firm-level sums of net transaction directions,
net numbers of shares, and net volumes of shares, respectively. Third,
within each country and region sub-sample, , , and are
standardized as follows
where denotes the country-/region-specific sub-sample, and ,
, and are the standardized monthly firm-level transaction
directions, number of shares, and volume of shares traded. Finally, for
each country and region, standardized aggregate net number of
transactions ( ), standardized aggregate net number of shares
( ), and standardized aggregate net volume of shares ( ) are
computed as follows
∑
{ }
∑
{ }
∑
{ }
where denotes the number of firms in a given country, and ,
, and
are the one-month aggregate insider sentiment
indicators. Using standardized indicators allows for more effective
interpretation as it limits the variables’ ranges, allows for improved
comparison of coefficients across models, and smoothens out variation in
the respective sentiment indicator (Seyhun, 1992). Each monthly insider
sentiment indicator is also aggregated over three and six months (
{ }) to smoothen out variability of corporate insider sentiment and to
reduce the influence of short-term trends.
The dependent variables in each model are the future one-month,
three-month, six-month, and twelve-month stock market index returns.
Previous studies conceptualized excess returns of an index relative to risk-
free assets as a measure of future market returns (Lakonishok & Lee,
2001; Seyhun, 1992). We use actual index holding returns to remove one
potential source of sensitivity stemming from the choice of risk-free return
rates. Our results thus allow for statements about the predictability of
insider sentiment for future market returns (the actual relation intended to
show) as opposed to future excess market returns which may differ
substantially. This study’s returns are defined as follows
(
)
{ }
where is the linear index holding return of the forecast horizon
of one, three, six, or twelve months; is the index’s price on the first
trading day of a given month following the end of an aggregation horizon;
and is the index’s price on the last trading day months after
the beginning of the forecast horizon month . Including long-term future
returns in the analysis ensures that the potential influence of short-term
seasonalities in stock returns or insider trading are mitigated.
Operationally, given data availability, all four forecast horizons are
calculated for the first month in the data set. Then, the four forecast
windows’ start and end points are both moved one month ahead. This
implies that forecast horizons can be overlapping. For instance, as the
twelve-month window is shifted one month ahead, the window implicitly
covers eleven months of the previous ’s twelve-month forecast window.
To establish the coefficients of interest, we run ordinary least square
regressions. A lagged return variable is introduced as an additional
independent variable in each regression model to account for serially
correlated residuals resulting from overlapping time periods. The lagged
variable is defined as the dependent variable at , which means that, for
6 Aggregate Trading by Insiders and Future Market Returns in the US, Europe, and Asia
instance, to predict the future six and twelve months index returns starting
February of a given year, the lagged variables used are the future six and
twelve months returns starting January of the same year. The regression
models are set up as follows
∑ { }
where are the returns to be predicted within the one, three, six,
or twelve months forecast horizons; is the coefficient of interest
showing the relation between aggregate insider sentiment and future index
returns; the sigma sign indicates the aggregation horizon, which starts
months and ends one month prior to a forecast horizon’s starting month
; is the lagged variable, i.e., the one, three, six, or twelve month
returns starting at the month before the focal month ;
and is a residual error term.
4. Empirical Results
Key variables’ descriptive statistics for selected countries are reported
in Table II. Descriptive statistics for all countries and regions (i.e., the US,
Europe-combined, Asia-combined, and individual European and Asian
countries) are shown in Table IV in the appendix. For each variable the
mean, standard deviation, minimum, and maximum are shown. The three
sentiment indicators and returns were calculated as laid out above. The
number of observations is the number of calendarmonths for the one-
month explanatory variable and the number of sums for the multi-month
explanatory variables, respectively. A negative (positive) mean sentiment
indicator implies that in aggregate insiders were net sellers (buyers)
during the period of time under consideration. , , and
standard deviations and ranges tend to increase with an increase in
aggregation horizons.
Table 2 Appendix B
Time series regression model results for selected countries are shown
in Table III. Results for all countries and regions are shown in Table V in
the appendix. Each model predicts the dependent variable, future market
return, as a function of the independent variable, insider sentiment. For
each region or country, future one-month, three-month, six-month, and
twelve-month buy-and-hold stock market returns are regressed on the
three different insider sentiment indicators reflecting aggregated
transactions over one, three, or six months ( , , ;
, , ; and , , ). Country- and
region-specific returns and insider sentiment indicators are calculated as
laid out in the methods part above.
Table 3 Appendix C
In each panel, the first columns demonstrate the relation between the
independent variable and the following month’s return, the associated
sample size of individual months or aggregations of months, and the
respective model’s . The following columns reveal the relation
between the sentiment indicator and the following three-, six-, and twelve-
month returns, respectively, the associated sample sizes, and
s. For each country, the first row relates to the one-month sentiment
indicator. The following rows show the model coefficients based on
values smoothed over three and six months, respectively. The
coefficients indicate the strength of the relationship between the
respective sentiment indicator and future market returns. The intercept
coefficients and lagged autoregressive coefficients are not of interest
for this analysis and thus omitted from the table. s are
increasing with the dependent variable’s time frame due to the lagged
variables’ large coefficients. Differences in s across the three
sentiment indicators are negligible.
The first Panel for each country shows the results for models in which
standardized aggregate net number of transactions were used. The results
imply that, for instance, an increase in one-month US by one
standard deviation, is associated with an expected increase of future six-
month S&P 500 returns by 2 percent. The second Panels feature the
results of models using standardized aggregate net number of shares.
Considering, for instance, Luxembourg, the Panel shows that an increase
of six-months by one standard deviation is expected to result in a
2.86 percent increase of future twelve-month LuxX Index returns. In the
third set of Panels, models reveal the results using standardized aggregate
net volume of shares as a proxy for corporate insider sentiment. The
results show that, for instance, an increase in three-month Asia-combined
by one standard deviation is associated with an expected increase in
the MSCI AC Asia ex Japan Index by 1.75 percent.
Overall, the results exhibit absence of one single monotonic trend
persisting across all countries, time frames, and sentiment indicators.
Insider sentiment is coherently significantly associated with future returns
in only some countries. For the US, Luxembourg, Switzerland, Poland,
India, and the Philippines, the presence of at least one significantly
positive coefficient in two sentiment indicators indicates that an
increase in insider sentiment can be reliably linked to higher future
returns. For Asia-combined and China, at least one significantly positive
coefficient in all three sentiment indicators suggests a homogeneously
positive relation. For all other 27 countries and regions in the sample,
results are either inconclusive, convey a mixture of positive and negative
signals across the economic models, or suggest negative associations
between insider sentiment and future returns. For instance, for Canada and
Austria, at least one significantly negative coefficient in each sentiment
indicator coherently implies a negative correlation between insider
sentiment and future market returns.
Comparing the three measurement instruments, it becomes apparent
that captures more associations between insider sentiment and
future returns than the other two ones, as the first Panel in each country
features more significant coefficients than the second and third Panel.
Furthermore, the first Panels show that within one country,
coefficients are mostly internally coherent, i.e., in all countries apart from
Greece, statistically significant s across time frames are of the same
sign. Another trend that can be observed is that for a given , the
sentiment indicators’ time period, coefficients tend to become more
positive as , the future returns’ time period, increases. In other words,
-based models’ forecast ability increases as the time period to be
predicted increases. Consider Hong Kong, where the three-months and
six-months smoothened sentiment indicators are statistically
insignificant in the models predicting future one-month, three-month, and
six-month Hong Kong Hang Seng Index (HSI) returns. Both sentiment
indicators are, however, significantly positively associated with future
twelve-month HSI returns. Similarly, examining Hong Kong’s one-month
7 Aggregate Trading by Insiders and Future Market Returns in the US, Europe, and Asia
coefficients shows a stronger relationship with predicted future
twelve-month returns than with predicted future six-month returns. In this
particular case, all else being equal, if increases by one standard
deviation, future six-month HSI returns are expected to rise by 2.06
percent whereas future twelve-month HSI returns are expected to rise by
2.85 percent.
The second and third Panels show that - and -based models
tend to introduce more noise than -based ones. For instance, for
Sweden, Singapore, and Thailand, -based models coherently
indicate a positive relation between insider sentiment and future market
returns across multiple dependent and independent variables’ time frames.
However, the overall country-level results are rendered ambiguous as
-based models indicate a negative relationship and -based
ones do not feature any statistically significant coefficients.
Furthermore, only transaction count-based results are robust to
changes in . Smoothing sentiment indicators over time by summing
multiple months’ standardized aggregate net number of transactions does
not alter results substantially. and -based models, however,
are sensitive to smoothed values. For instance, summing Germany-based
insiders’ standardized aggregate net numbers of shares over three months
changes the coefficients’ signs from negative to positive. Similarly,
summing Hong Kong-based insiders’ standardized aggregate net volumes
of shares over multiple months changes the coefficients’ sign from
positive to negative.
5. Discussion
We find evidence consistent with what Zhu et al. (2014) considers the
insiders’ “macro information advantage” for some countries in our
sample. The regression results indicate that in the US, Luxembourg,
Switzerland, Poland, India, the Philippines, Asia-combined, and China
aggregate insider trading coherently predicts future market returns.
Insiders seem to be able to observe and trade on market-wide activities
and trends in said countries. This ability may be due to insiders obtaining
macroeconomic information earlier, analyzing information more
effectively, and perceiving systematic stock market mispricings better
than other market participants. In the aforementioned countries, insider
sentiment forecast abilities are economically significant. An increase in
aggregate insider buying by one standard deviation is associated with rises
of around 2 percent. Market participants wishing to implement a low-cost
tool to forecast stock market returns can use publicly available insider
filings to deduce insider sentiments for these countries.
In contrast, our data suggests that insiders in Europe-combined,
Germany, France, the United Kingdom, Italy, Russia, Spain, the
Netherlands, Sweden, Belgium, Austria, Norway, Ireland, Denmark,
Finland, Romania, Greece, Cyprus, Turkey, Hong Kong, Korea, Australia,
New Zealand, Malaysia, Singapore, and Thailand do not base their trades
on macroeconomic expectations and information. Insiders in these
countries rather seem to base their trades predominantly on firm-specific
information. Insiders seem to be more effective in obtaining and trading
on cash flow news related to their own firms. Market participants do not
seem to be able to use aggregate insider trading as a tool to forecast future
market returns in these countries.
Additionally, there are three categories of reasons (market-, firm-, and
insider-level) which provide potential explanations as to why aggregate
insider trading does not predict market returns in these countries. First,
from a market-level perspective there might be differences in insider
trading regulation implementation and enforcement allowing insiders in
the second set of countries to trade on firm-specific cash flow information
without fearing a high risk of litigation. Differences in firm-level
abnormal returns have previously been ascribed to regulatory differences
(Fidrmuc, Korczak, & Korczak, 2013). Other aspects that may harm
insiders’ ability to trade on macroeconomic expectations include the level
of market maturity and efficiency. In modern times, all market
participants have fast access to a plethora of information and means to
analyze data. It is thus likely that insiders’ macro information advantage
relative to other investors has vanished in some countries as every market
participant trades on the same (publicly) available data. Moreover, the
degree of specialization in a given economy might be positively
associated with insiders’ forecasting abilities as specialized firms may
tend to have more interactions with other firms than non-specialized ones,
allowing them to gather macroeconomic information through frequent
interaction. Second, extant research suggests an impact of firm size
(Lakonishok & Lee, 2001; Seyhun, 1988), firm market risk (Seyhun,
1988), and governance and ownership structures (Zhu et al., 2014) on the
predictive power of aggregate insider trading. It is possible that some of
the results presented above are influenced by these aspects. For instance,
Lakonishok and Lee (2001) claimed that insiders in smaller companies
have greater predictive power. It is possible that in the sample, countries
that do not reveal a significant relation between insider sentiment and
market returns feature an unproportionally huge number of large firms.
Third, prior research indicated that managers exhibit higher predictive
power than large shareholders (Lakonishok & Lee, 2001), and that levels
of hierarchy and operational involvement are positively correlated with
insiders’ predictive power (Lakonishok & Lee, 2001; Zhu et al., 2014). It
may be possible that in the sample, countries that do not reveal a
significant relation between insider sentiment and market returns feature a
relatively high amount of large shareholders’ transactions and insiders of
low hierarchical level. Additionally, in countries for which future returns
can be predicted by aggregate insider trading, corporate insiders might be
better inter-connected, allowing them to gather and deduce
macroeconomic information more effectively. All aforementioned aspects
may also interact differently across countries.
In line with e.g. Lakonishok and Lee (2001) we find that the models’
forecast ability becomes of greater magnitude as the forecast horizon
increases. This increase is likely due to insiders observing trends very
early, which only substantiate and become noticed by outside investors
over the course of time. Another noteworthy pattern in the results is that
models for smaller economies in terms of market activity, number of
firms, or GDP tend to reveal more significant relations between aggregate
insider trading and market returns than those for larger economies. This
trend may be due to insiders in smaller countries being more
interconnected, which allows them to build up macroeconomic trends
more effectively as their access to economy-wide information increases.
The second and third Panels of Tables III and V present some
mixed evidence. Accordingly, the overall assessment as to whether
insiders base transactions on superior economy-wide knowledge is
rendered inconclusive for Germany, Sweden, Hong Kong, Singapore, and
Thailand. The nonuniform nature of - and -based models is in
line with previous studies (Seyhun, 1992). Extant research demonstrated
that insider transactions in smaller firms are associated with greater
abnormal returns (Lakonishok & Lee, 2001), which implies that insiders
in such firms tend to possess greater firm-specific insights. Directors in
8 Aggregate Trading by Insiders and Future Market Returns in the US, Europe, and Asia
larger firms, who tend to possess and trade on less firm-specific
information, tend to buy and sell higher numbers and volumes of shares,
which results in - and -based models being biased towards
such firms. The fact that these models provide less conclusive evidence
than -based ones suggests that large-firm insiders do also not
possess superior economy-wide information.
Our findings are generally consistent with past studies. Seyhun (1988)
showed that one standard deviation change in aggregate insider trading
predicts up to 1.7 percent change in future excess market returns. We
documented that an increase in one-month US by one standard
deviation is associated with an expected increase of future six-month S&P
500 returns by 2 percent. Similar to Seyhun (1992), we find that using
standardized aggregate net number of shares as an indicator for insider
sentiment leads produces more noisy future return predictions than the
standardized aggregate net number of transactions. Our findings
pertaining to China and other less mature markets (i.e., India and the
Philippines) are in line with Zhu et al. (2014).
Apart from the novelty of our data and the geographical breadth of our
sample, the main strength of our exploratory study lies in the
methodological rigor applied. By defining three distinct insider trading
measures we avoid potential biases arising from using only one single
indicator. For instance, aggregate dollar volume as a measure of aggregate
trading might be influenced by large firms and a small number of large
transactions, whereas the transaction count may be less biased. Monthly
insider sentiment indicators are smoothened out to reduce the variability
of corporate insider sentiment and to reduce the influence of short-term
trends. Sentiment aggregations of one, three, and six month(s) are
examined, as opposed to other studies (e.g., Chowdhury et al., 1993) who
used short-term sentiment aggregation horizons of as little as one week. A
similar logic applies to long-term forecast horizons, chosen to mitigate the
potential influence of seasonalities. Moreover, we use holding returns as
opposed to, for instance, excess returns, as the dependent variable in order
to analyze the actual predicted relation and to avoid one potential source
of bias introduced by choosing appropriate risk-free assets. One potential
weakness of our study is the high level of analysis. We do not consider
differences in transaction, insiders, or firm types. For instance,
Chowdhury et al. (1993) showed that aggregate insider purchases have a
greater predictive power than aggregate insider sales. However, we do not
effectively account for such potential differences.
6. Conclusion & Future Research
This study examines aggregate insider transactions in 21 European
and 10 Asian countries and the US. We find that only in the US,
Luxembourg, Switzerland, Poland, Asia-combined, China, India, and the
Philippines insiders do coherently predict future market returns. Insiders
in these countries seem to trade on economy-wide expectations, whereas
in other countries in the sample, insiders appear to trade predominantly on
firm-specific private information. For the aforementioned seven countries,
investors can use aggregate insider trading as an effective tool to make
assumptions about future stock market returns and use insider sentiment
to inform passive or index investing strategies. On the contrary, in those
countries in which aggregate insider trading is uncorrelated with future
market returns, insiders appear to rather trade on firm-specific
information. Accordingly, investment strategies focusing on using
individual firms’ insider trading filings to invest in particular stocks may
be more profitable. The findings imply that naively mimicking all insider
transactions is not necessarily a profitable investment strategy.
This high-level study does not examine transaction (e.g., buy vs sell),
firm (e.g., size, risk), or insider (e.g., hierarchical level, operational
involvement) characteristics. The discussion section of this paper provides
multiple reasons as to why insider sentiment in terms of aggregate insider
trading may not be an accurate predictor for some countries in the sample.
Multiple testable hypotheses to be empirically analyzed can be developed
from the discussion. We leave this to further research.
