Problem 1:

You invest in a portfolio of 5 stocks with an equal investment in each one. The betas of the 5 stocks are as follows: .75, -1.2, .90, 1.3, 1.5. The risk free return is 4% and the market return is 9%. (Not a multiple choice problem)

A. Compute the beta of the portfolio

B. Compute the required return of the portfolio

Problem 2:

You are given the following probability distribution for a stock: (Not a multiple choice problem)

Pr. Outcome.5
.4 10%
.1 -6%
.5 12%

A. Compute the expected return of this stock

B. Compute the standard deviation

Problem 3:

You are given the following probability distribution for a stock: (Not a multiple choice problem)


Pr. Outcome.6
.4 -4%
.6 12%

A. Compute the expected return

B. Compute the standard deviation

C. Presuming the stock returns are normally distributed, what do these results indicate?

Problem 4:

A stock has a beta of 0.8. The market return is 14% and the risk free return is 3%. Compute the required return for this stock.

Problem 6-14

Suppose that many stocks are traded in the market and that it is possible to borrow at the risk-free rate,rƒ. The characteristics of two of the stocks are as follows:
Stock Expected Return Standard Deviation
A 6 % 25 %
B 10 % 75 %
Correlation = –1
a.

Calculate the expected rate of return on this risk-free portfolio? (Hint: Can a particular stock portfolio be substituted for the risk-free asset?) (Round your answer to 2 decimal places.)

Market portfolio has an expected return of 11% and volatility of 20%. Risk-free rate is 3%. Security X and Y have betas of 1.4 and 0.9 respectively.

a) According to CAPM, what are the expected return of X and Y?

E(rm)-rf = 11% - 3% = 8%

3% +1.4*8% = 14.2%

3% +1.4 *8% = 10.2%

b) What should be X worth today, if X pays a dividend of $1.2 one year from today and is priced at 30 one year from today? The required rate of return is the expected return using CAPM from part a).

c) If security X has expected return of 15%, is it underprice/overprice/fairly priced according to CAPM? What is its alpha?

d) Plot SML and label X, Y and Market portfolio on the line.

e) What is the beta of a portfolio with 50% in X and 50% in Y?
