Motivation
In August of 2004, Google went public, auctioning its shares in an unusual
IPO format. The shares originally sold for $85 / share, and closed at over
$100 on the first day. At the end of 2012, shares are trading on Nasdaq at
over $707 / share.

Investing in Stocks
1. Represents ownership
in a firm
4. Right to vote for directors and
on certain issues
2. Earn a return in
two ways
– Price of the stock rises
over time
– Dividends are paid to the
stockholder
5. Two types
– Common stock
▪ Right to vote
▪ Receive dividends
– Preferred stock
▪ Receive a fixed dividend
▪ Do not usually vote
3. Stockholders have claim on
all assets

Stock Market Indices
▪ Stock market indexes are frequently used to monitor the behavior of a groups
of stocks.
▪ Major indexes include the Dow Jones Industrial Average, the S&P 500, and
the NASDAQ composite.

Stock Market Indexes

Bears vs. Bulls
▪ A bull market occurs when stock
prices (as measured by an index like
the Dow Jones Industrial or the S&P
500) move up.
▪ A bear market occurs when stocks
fall.
▪ More specifically, bear markets
generally occur when the market has
fallen by greater than 20 percent
from its highs, and a correction
occurs when the market has fallen by
more than 10 percent but less than 20
percent.

Investing in Stocks: How Stocks are Sold
• Organized exchanges
– NYSE is best known, with daily volume around 4 billion shares, with
peaks at 10 billion.
– “Organized” used to imply a specific trading location. But computer
systems (ECNs) have replaced this idea.
– Listing requirements exclude small firms.
9
Investing in Stocks: How Stocks are Sold
• Over-the-counter markets
– Best example is NASDAQ (National Association of Securities Dealers
Automated Quotations)
– Dealers stand ready to make a market
– Important market for thinly-traded securities—securities that don’t trade
very often. Without a dealer ready to make a market, the equity would be
difficult to trade.
10
Investing in Stocks: Organized vs. OTC
• Organized exchanges (e.g., NYSE)
– Auction markets with floor specialists
– 25% of trades are filled directly by specialist
– Remaining trades are filled through SuperDOT
• Over-the-counter markets (e.g., NASDAQ)
– Multiple market makers set bid and ask prices
– Multiple dealers for any given security
11
Investing in Stocks: ECNs
ECNs (electronic communication networks) allow brokers and traders to trade
without the need of the middleman. They provide:
• Transparency: everyone can see unfilled orders
• Cost reduction: smaller spreads
• Faster execution
• After-hours trading
12
Investing in Stocks: ETFs
Exchange Traded Funds are a recent innovation to help keep transaction costs down
while offering diversification.
▪ Represent a basket of securities
▪ Traded on a major exchange
▪ Index to a specific portfolio (e.g., the S&P 500), so management fees are low
(although commissions still apply)
▪ Exact content of basket is known, so valuation is certain
13
Computing the Price of Common Stock
• Valuing common stock is, in theory, no different from valuing debt securities:
– determine the cash flows
– discount them to the present
• We will review four different methods for valuing stock, each with its
advantages and drawbacks.
14
Computing the Price of Common Stock: The One-Period Valuation
Model
• Simplest model, just taking the expected dividend and price over the next year.
• P = the current price of the stock. The zero subscript refers to time period zero, or the present.
0
• Div = the dividend paid at the end of year 1.
1
• k = the required return on investments in equity.
e
• P = the price at the end of the first period. This is the assumed sales price of the stock.

15
Computing the Price of Common Stock: The One-Period Valuation Model
Example: What is the price for a stock with an expected dividend and price next
year of $0.16 and $60, respectively? Use a 12% discount rate
Answer:
Price = (0.16 + 60) / (1 + 0.12) = $ 53.71
16
Computing the Price of Common Stock: The Generalized Dividend Valuation
Model
▪ The concept remains the same. The value of stock is the present value of all future
cash flows.
▪ You must find P in order to find P !!!!!!
n
0
▪ if P is far in the future, it will not affect P
n
0
▪ The generalized dividend model is rewritten without the final sales
price.

Model
Questions!!!
▪ Many stocks do not pay dividends, so how is it that these stocks have value? Buyers of the stock
expect that the firm will pay dividends someday. Most of the time a firm institutes dividends as
soon as it has completed the rapid growth phase of its life cycle.
▪ The generalized dividend valuation model requires that we compute the present
value of an infinite stream of dividends, a process that could be difficult
18
Computing the Price of Common Stock: The Generalized Dividend Valuation
Model (The Gordon Growth Model)
▪ The generalized dividend valuation model requires that we compute the present value of an
infinite stream of dividends, a process that could be difficult.
▪ Simplified models have been developed to make the calculations easier. One such model is
the Gordon growth model.
▪ The Gordon growth model that assumes constant dividend growth.
19
Computing the Price of Common Stock: The Generalized Dividend Valuation
Model
▪ Where,
P0= the price per share
D0 = the most recent dividend paid
g = the expected constant growth rate in dividends
ke = the required return on an investment in equity

Computing the Price of Common Stock: The Generalized Dividend Valuation
Model
▪ Where,
P0= the price per share
D0 = the most recent dividend paid
g = the expected constant growth rate in dividends
ke = the required return on an investment in equity
The model is useful, with the following assumptions:
• Dividends do, indeed, grow at a constant rate forever
• The growth rate of dividends, g, is less than the required return on the equity, ke.
23
Computing the Price of Common Stock: The Generalized Dividend Valuation
Model
Example: Find the current market price of Coca-Cola stock assuming dividends grow at a
constant rate of 10.95%, D0 = $1.00, and the required return is 13%.
Solution:
Coca-Cola stock should sell for $54.12 if the assumptions regarding the constant growth
rate and required return are correct.
24
Computing the Price of Common Stock: The Price Earnings Valuation
Method
The price earnings ratio (PE) is a widely watched measure of how much the market
is willing to pay for $1 of earnings from a firm.
A high PE has two interpretations.
1. A higher-than-average PE may mean that the market expects earnings to rise in the future. This
would return the PE to a more normal level.
2. A high PE may alternatively indicate that the market feels the firm’s earnings are very low risk and
is therefore willing to pay a premium for them.
25
Computing the Price of Common Stock: The Price Earnings Valuation
Method
Example: The average industry PE ratio for restaurants similar to Applebee’s, a
pub restaurant chain, is 23. What is the current price of Applebee’s if earnings per
share are projected to be $1.13?
Solution:
P = 23 X $1.13 = $26
0
26
How the Market Sets Security Prices
• Generally speaking, prices are set in competitive markets as the price set by
the buyer willing to pay the most for an item.
• The buyer willing to pay the most for an asset is usually the buyer who can
make the best use of the asset.
• Superior information can play an important role.
27
• Suppose that you are considering the purchase of stock expected to pay
dividends of $2 next year (D1= $2). The firm is expected to grow at 3%.
Consider the following three valuations for a stock with certain dividends but
different perceived risk:
Investor
Discount Rate
Stock Price
You
15%
$16.67
Sara
12%
$22.22
Sami
7%
$50.00
• Sami, who perceives the lowest risk, is willing to pay the most and will
determine the “market” price.
28
Errors in Valuation
Although the pricing models are useful, market participants frequently encounter
problems in using them. Any of these can have a significant impact on price in the
Gordon model.
• Problems with Estimating Growth
• Problems with Estimating Risk
• Problems with Forecasting Dividends
