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
4. 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.
5. 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: 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.

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.
12. 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 at
2004 $1.75 2.94% Year: 7.96%:
2003 $1.70 13.33% 2002 $1.50
2002 $1.50 2003 $1.62

14. 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%
15. 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?
18. 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.?
20. 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
21. 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:
million.

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
23. 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.
24. 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.
25. 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.
26. 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.
30. 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.
31. 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.

An Analysis of the
McGraw-Hill Company
The next few slides contain a financial
analysis of the McGraw-Hill Company, using
data from the Value Line Investment Survey.
38. 6-38
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)
39. 6-39
The McGraw-Hill Company Analysis
(Using the Residual Income Model, I)
• Let’s assume that “today” is January 1, 2008, g = 7.5%, and k = 12.6%.
• Using the Value Line Investment Survey (VL), we can fill in column two

• We use column one and our growth assumption for column three (CSR) of
