Now, let’s talk about Capital Asset
Pricing Model
15Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
CAPM is a model that describes the relationship between risk and expected
(required) return; in this model, a security’s expected (required) return is the risk-free rate plus a premium based on the
systematic risk of the security.

CAPM Assumptions
17Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
The CAPM equationThe CAPM equation::
kj = krf + j(km - krf)
where:
kj = the Required Return on security j,
krf = the risk-free rate of interest,
j = the beta of security j, and
km = the return on the market index.
Also referred as SML (discussed in subsequent slides)
18Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
Example:Example:
Suppose the Treasury bond rate is 6%, the average return on the KSE 100 index is 12%, and OGDC has a beta of 1.2.
According to the CAPM, what should be the required rate of return on OGDC stock?
19Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
kj = .06 + 1.2 (.12 - .06)
kj = .132 = 13.2%
According to the CAPM, OGDC
stock should be priced to give
a13.2% return.
kj = krf + j (km - krf)

Beta
Measures a stock’s market risk, and shows a stock’s volatility relative to the market. In other words, it measures the sensitivity of a stock’s returns to changes in returns on the market portfolio.
Indicates how risky a stock is if the stock is held in a well-diversified portfolio.Its an index of systematic risk.
The beta for a portfolio is simply a weighted average of the individual stock betas in the portfolio.
21Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
Calculating betas
Run a regression of past returns of a security against past returns on the market.
The slope of the regression line (sometimes called the security’s characteristic line) is defined as the beta coefficient for the security.

Comments on beta
If beta = 1.0, the security is just as risky as the average stock.
If beta > 1.0, the security is riskier than average.
If beta < 1.0, the security is less risky than average.
Most stocks have betas in the range of 0.5 to 1.5.
25Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
Can the beta of a security be negative?
Yes, if the correlation between Stock i and the market is negative (i.e., ρi,m < 0).
If the correlation is negative, the regression line would slope downward, and the beta would be negative.
However, a negative beta is highly unlikely.

What is the market risk premium?
Additional return over the risk-free rate needed to compensate investors for assuming an average amount of risk.
Its size depends on the perceived risk of the stock market and investors’ degree of risk aversion.
Varies from year to year, but most estimates suggest that it ranges between 4% and 8% per year.

An example:Equally-weighted two-stock portfolio
Create a portfolio with 50% invested in HT and 50% invested in Collections.
The beta of a portfolio is the weighted average of each of the stock’s betas.
βP = wHT βHT + wColl βColl
βP = 0.5 (1.30) + 0.5 (-0.87)
βP = 0.215
46Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
Calculating portfolio required returns
The required return of a portfolio is the weighted average of each of the stock’s required returns.
kP = wHT kHT + wColl kColl
kP = 0.5 (17.1%) + 0.5 (1.9%)
kP = 9.5%
Or, using the portfolio’s beta, CAPM can be used to solve for expected return.
kP = kRF + (kM – kRF) βP
kP = 8.0% + (15.0% – 8.0%) (0.215)
kP = 9.5%
47Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
Verifying the CAPM empirically
The CAPM has not been verified completely.
Statistical tests have problems that make verification almost impossible.
Some argue that there are additional risk factors, other than the market risk premium, that must be considered.
48Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
More thoughts on the CAPM
Investors seem to be concerned with both market risk and total risk. Therefore, the SML may not produce a correct estimate of ki.
ki = kRF + (kM – kRF) βi + ???
CAPM/SML concepts are based upon expectations, but betas are calculated using historical data. A company’s historical data may not reflect investors’ expectations about future riskiness.

Lets recall from before three ways to determine the cost of equity, ke or ks :
1. Capital Asset Pricing Model (CAPM)
ks = kRF + (kM - kRF)b
2. Dividend-Yield-Plus-Growth-Rate-Approach (DCF)
ks = D1/P0 + g.
3. Bond-Yield-Plus-Risk-Premium-Approach:
ks = kd + RP.
51Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
What’s the cost of equity based on the CAPM?
kRF = 7%, RPM = 6%, b = 1.2.
ks = kRF + (kM - kRF )b.
= 7.0% + (6.0%)1.2 = 14.2%.

What factors influence a company’s WACC?
Market conditions, especially interest rates and tax rates.
The firm’s capital structure and dividend policy.
The firm’s investment policy. Firms with riskier projects generally have a higher WACC.
63Copyright © 2009, FM, Prepared by Amyn Wahid All rights reserved.
Should the company use the composite WACC as the hurdle rate for
each of its projects?
NO! The composite WACC reflects the risk of an average project undertaken by the firm. Therefore, the WACC only represents the “hurdle rate” for a typical project with average risk.
Different projects have different risks. The project’s WACC should be adjusted to reflect the project’s risk.
