CHAPTER 13 B-237

9. Such layoffs generally occur in the context of corporate restructurings. To the extent that the market

views a restructuring as value-creating, stock prices will rise. So, it’s not layoffs per se that are being

cheered on. Nonetheless, Wall Street does encourage corporations to takes actions to create value, even

if such actions involve layoffs.

10. Earnings contain information about recent sales and costs. This information is useful for projecting

future growth rates and cash flows. Thus, unexpectedly low earnings often lead market participants to

reduce estimates of future growth rates and cash flows; price drops are the result. The reverse is

often true for unexpectedly high earnings.

Solutions to Questions and Problems

NOTE: All end of chapter problems were solved using a spreadsheet. Many problems require multiple steps.

Due to space and readability constraints, when these intermediate steps are included in this solutions

manual, rounding may appear to have occurred. However, the final answer for each problem is found

without rounding during any step in the problem.

Basic

1. The portfolio weight of an asset is total investment in that asset divided by the total portfolio value.

First, we will find the portfolio value, which is:

Total value = 180($45) + 140($27) = $11,880

2. The expected return of a portfolio is the sum of the weight of each asset times the expected return of

each asset. The total value of the portfolio is:

Total value = $2,950 + 3,700 = $6,650

3. The expected return of a portfolio is the sum of the weight of each asset times the expected return of

B-238 SOLUTIONS

4. Here we are given the expected return of the portfolio and the expected return of each asset in the

portfolio, and are asked to find the weight of each asset. We can use the equation for the expected return

of a portfolio to solve this problem. Since the total weight of a portfolio must equal 1 (100%), the

weight of Stock Y must be one minus the weight of Stock X. Mathematically speaking, this means:

E(Rp) = .124 = .14wX + .105(1 – wX)

5. The expected return of an asset is the sum of the probability of each return occurring times the

6. The expected return of an asset is the sum of the probability of each return occurring times the

7. The expected return of an asset is the sum of the probability of each return occurring times the

probability of that return occurring. So, the expected return of each stock asset is:

E(RA) = .15(.05) + .65(.08) + .20(.13) = .0855 or 8.55%

E(RB) = .15(–.17) + .65(.12) + .20(.29) = .1105 or 11.05%

To calculate the standard deviation, we first need to calculate the variance. To find the variance, we find

the squared deviations from the expected return. We then multiply each possible squared deviation by

8. The expected return of a portfolio is the sum of the weight of each asset times the expected return of

each asset. So, the expected return of the portfolio is:

9. a. To find the expected return of the portfolio, we need to find the return of the portfolio in each state

of the economy. This portfolio is a special case since all three assets have the same weight. To find

the expected return in an equally weighted portfolio, we can sum the returns of each asset and

b. This portfolio does not have an equal weight in each asset. We still need to find the return of the

portfolio in each state of the economy. To do this, we will multiply the return of each asset by its

portfolio weight and then sum the products to get the portfolio return in each state of the economy.

Doing so, we get:

Boom: E(Rp) = .20(.07) +.20(.15) + .60(.33) =.2420 or 24.20%

B-240 SOLUTIONS

10. a. This portfolio does not have an equal weight in each asset. We first need to find the return of the

portfolio in each state of the economy. To do this, we will multiply the return of each asset by its

portfolio weight and then sum the products to get the portfolio return in each state of the economy.

Doing so, we get:

Boom: E(Rp) = .30(.3) + .40(.45) + .30(.33) = .3690 or 36.90%

b. To calculate the standard deviation, we first need to calculate the variance. To find the variance,

we find the squared deviations from the expected return. We then multiply each possible squared

deviation by its probability, than add all of these up. The result is the variance. So, the variance

11. The beta of a portfolio is the sum of the weight of each asset times the beta of each asset. So, the beta of

the portfolio is:

12. The beta of a portfolio is the sum of the weight of each asset times the beta of each asset. If the portfolio

is as risky as the market it must have the same beta as the market. Since the beta of the market is one,

we know the beta of our portfolio is one. We also need to remember that the beta of the risk-free asset is

CHAPTER 13 B-241

13. CAPM states the relationship between the risk of an asset and its expected return. CAPM is:

E(Ri) = Rf + [E(RM) – Rf] × i

14. We are given the values for the CAPM except for the  of the stock. We need to substitute these values

into the CAPM, and solve for the  of the stock. One important thing we need to realize is that we are

given the market risk premium. The market risk premium is the expected return of the market minus the

15. Here we need to find the expected return of the market using the CAPM. Substituting the values given,

and solving for the expected return of the market, we find:

16. Here we need to find the risk-free rate using the CAPM. Substituting the values given, and solving for

the risk-free rate, we find:

17. a. Again we have a special case where the portfolio is equally weighted, so we can sum the returns of

B-242 SOLUTIONS

b. We need to find the portfolio weights that result in a portfolio with a  of 0.95. We know the  of

the risk-free asset is zero. We also know the weight of the risk-free asset is one minus the weight

c. We need to find the portfolio weights that result in a portfolio with an expected return of 8 percent.

We also know the weight of the risk-free asset is one minus the weight of the stock since the

portfolio weights must sum to one, or 100 percent. So:

E(Rp) = .08 = .16wS + .048(1 – wS)

d. Solving for the  of the portfolio as we did in part a, we find:

p = 2.70 = wS(1.35) + (1 – wS)(0)

18. First, we need to find the  of the portfolio. The  of the risk-free asset is zero, and the weight of the

risk-free asset is one minus the weight of the stock, the  of the portfolio is:

p = wW(1.25) + (1 – wW)(0) = 1.25wW

So, to find the  of the portfolio for any weight of the stock, we simply multiply the weight of the stock

times its .
