Common Stock Valuation
• Our goal in this chapter is to examine the methods commonly used by financial analysts to assess the economic value of common stocks.
• These methods are grouped into three categories:– Dividend discount models– Residual Income models– Price ratio models
6-4
Security Analysis: Be Careful Out There
• Fundamental analysis is a term for studying a company’s accounting statements and other financial and economic information to estimate the economic value of a company’s stock.
• The basic idea is to identify “undervalued” stocks to buy and “overvalued” stocks to sell.
• In practice however, such stocks may in fact be correctly priced for reasons not immediately apparent to the analyst.
6-5
The Dividend Discount Model
• The Dividend Discount Model (DDM) is a method to estimate the value of a share of stock by discounting all expected future dividend payments. The basic DDM equation is:
• In the DDM equation:– P0 = the present value of all future dividends
– Dt = the dividend to be paid t years from now
– k = the appropriate risk-adjusted discount rate

Example: The Dividend Discount Model
• Suppose that a stock will pay three annual dividends of $200 per year, and the appropriate risk-adjusted discount rate, k, is 8%.
• In this case, what is the value of the stock today?

The Dividend Discount Model: the Constant Growth Rate Model
• Assume that the dividends will grow at a constant growth rate g. The dividend next period (t + 1) is:

Example: Constant Perpetual Growth Model
• Think about the electric utility industry. • In 2007, the dividend paid by the utility company, DTE Energy Co.
(DTE), was $2.12.
• Using D0 =$2.12, k = 6.7%, and g = 2%, calculate an estimated value for DTE.
Note: the actual mid-2007 stock price of DTE was $47.81.
What are the possible explanations for the difference?

The Dividend Discount Model:Estimating the Growth Rate
• The growth rate in dividends (g) can be estimated in a number of ways:
– Using the company’s historical average growth rate.
– Using an industry median or average growth rate.
– Using the sustainable growth rate.
6-12
The Historical Average Growth Rate
• Suppose the Broadway Joe Company paid the following dividends:
– 2002: $1.50 2005: $1.80– 2003: $1.70 2006: $2.00– 2004: $1.75 2007: $2.20
• The spreadsheet below shows how to estimate historical average growth rates, using arithmetic and geometric averages.
Year: Dividend: Pct. Chg:2007 $2.20 10.00%2006 $2.00 11.11%2005 $1.80 2.86% Grown at2004 $1.75 2.94% Year: 7.96%:2003 $1.70 13.33% 2002 $1.502002 $1.50 2003 $1.62

2006 $2.047.96% 2007 $2.20

The Sustainable Growth Rate
• Return on Equity (ROE) = Net Income / Equity
• Payout Ratio = Proportion of earnings paid out as dividends
• Retention Ratio = Proportion of earnings retained for investment
Ratio) Payout - (1 ROE
Ratio Retention ROE Rate Growth eSustainabl
6-14
Example: Calculating and Using the Sustainable Growth Rate
• In 2007, American Electric Power (AEP) had an ROE of 10.17%, projected earnings per share of $2.25, and a per-share dividend of $1.56. What was AEP’s:– Retention rate?– Sustainable growth rate?
• Payout ratio = $1.56 / $2.25 = .693
• So, retention ratio = 1 – .693 = .307 or 30.7%
• Therefore, AEP’s sustainable growth rate = .1017 .307 = .03122, or 3.122%
6-15
Example: Calculating and Using the Sustainable Growth Rate, Cont.
• What is the value of AEP stock, using the perpetual growth model, and a discount rate of 6.7%?
• The actual mid-2007 stock price of AEP was $45.41.
• In this case, using the sustainable growth rate to value the stock gives a reasonably accurate estimate.
• What can we say about g and k in this example?

The Two-Stage Dividend Growth Model
• The two-stage dividend growth model assumes that a firm will initially grow at a rate g1 for T years, and
thereafter grow at a rate g2 < k during a perpetual second
stage of growth.

Using the Two-Stage Dividend Growth Model, I.
• Although the formula looks complicated, think of it as two parts:– Part 1 is the present value of the first T dividends (it is the same
formula we used for the constant growth model).– Part 2 is the present value of all subsequent dividends.
• So, suppose MissMolly.com has a current dividend of D0 = $5, which is expected to shrink at the rate, g1 = 10% for 5 years, but grow at the rate, g2 = 4% forever.
• With a discount rate of k = 10%, what is the present value of the stock?
6-18
Using the Two-Stage Dividend Growth Model, II.
• The total value of $46.03 is the sum of a $14.25 present value of the first five dividends, plus a $31.78 present value of all subsequent dividends.

Example: Using the DDM to Value a Firm Experiencing “Supernormal” Growth, I.
• Chain Reaction, Inc., has been growing at a phenomenal rate of 30% per year.
• You believe that this rate will last for only three more years.
• Then, you think the rate will drop to 10% per year.
• Total dividends just paid were $5 million.
• The required rate of return is 20%.
• What is the total value of Chain Reaction, Inc.?
6-20
Example: Using the DDM to Value a Firm Experiencing “Supernormal” Growth, II.
• First, calculate the total dividends over the “supernormal” growth period:
• Using the long run growth rate, g, the value of all the shares at Time 3 can be calculated as:
P3 = [D3 x (1 + g)] / (k – g)
P3 = [$10.985 x 1.10] / (0.20 – 0.10) = $120.835
Year Total Dividend: (in $millions)
1 $5.00 x 1.30 = $6.50
2 $6.50 x 1.30 = $8.45
3 $8.45 x 1.30 = $10.985
6-21
Example: Using the DDM to Value a Firm Experiencing “Supernormal” Growth, III.
• Therefore, to determine the present value of the firm today, we need the present value of $120.835 and the present value of the dividends paid in the first 3 years:

Discount Rates for Dividend Discount Models
• The discount rate for a stock can be estimated using the capital asset pricing model (CAPM ).
• We will discuss the CAPM in a later chapter. • However, we can estimate the discount rate for a stock using this
formula:
Discount rate = time value of money + risk premium
= U.S. T-bill Rate + (Stock Beta x Stock Market Risk Premium)
T-bill Rate: return on 90-day U.S. T-bills
Stock Beta: risk relative to an average stock
Stock Market Risk Premium: risk premium for an average stock
6-23
Observations on Dividend Discount Models, I.
Constant Perpetual Growth Model:
• Simple to compute• Not usable for firms that do not pay dividends• Not usable when g > k• Is sensitive to the choice of g and k• k and g may be difficult to estimate accurately.• Constant perpetual growth is often an unrealistic assumption.
6-24
Observations on Dividend Discount Models, II.
Two-Stage Dividend Growth Model:
• More realistic in that it accounts for two stages of growth• Usable when g > k in the first stage• Not usable for firms that do not pay dividends• Is sensitive to the choice of g and k• k and g may be difficult to estimate accurately.
6-25
Residual Income Model (RIM), I.
• We have valued only companies that pay dividends.
– But, there are many companies that do not pay dividends. – What about them?– It turns out that there is an elegant way to value these
companies, too.
• The model is called the Residual Income Model (RIM).
• Major Assumption (known as the Clean Surplus Relationship, or CSR): The change in book value per share is equal to earnings per share minus dividends.
6-26
Residual Income Model (RIM), II.
• Inputs needed:– Earnings per share at time 0, EPS0
– Book value per share at time 0, B0
– Earnings growth rate, g– Discount rate, k
• There are two equivalent formulas for the Residual Income Model:

Price Ratio Analysis, I.
• Price-earnings ratio (P/E ratio)– Current stock price divided by annual earnings per share (EPS)
• Earnings yield– Inverse of the P/E ratio: earnings divided by price (E/P)
• High-P/E stocks are often referred to as growth stocks, while low-P/E stocks are often referred to as value stocks.
6-30
Price Ratio Analysis, II.
• Price-cash flow ratio (P/CF ratio)– Current stock price divided by current cash flow per share– In this context, cash flow is usually taken to be net income plus
depreciation.
• Most analysts agree that in examining a company’s financial performance, cash flow can be more informative than net income.
• Earnings and cash flows that are far from each other may be a signal of poor quality earnings.
6-31
Price Ratio Analysis, III.
• Price-sales ratio (P/S ratio)– Current stock price divided by annual sales per share– A high P/S ratio suggests high sales growth, while a low P/S ratio
suggests sluggish sales growth.
• Price-book ratio (P/B ratio)– Market value of a company’s common stock divided by its book
(accounting) value of equity– A ratio bigger than 1.0 indicates that the firm is creating value for
its stockholders.

The McGraw-Hill Company Analysis, III.
• Based on the CAPM, k = 3.1% + (.80 9%) = 10.3%
• Retention ratio = 1 – $.66/$2.65 = .751
• Sustainable g = .751 23% = 17.27%
• Because g > k, the constant growth rate model cannot be used. (We would get a value of -$11.10 per share)
