What is the beta for a portfolio with an expected return of 12.5%?

A. , 0

B. , 1

C. , 1.5

D. , 2

C. , 1.5

GraphSince rf = 5% and E(rM) = 10%, from the CAPM we know that 12.5% = 5% + beta(10% - 5%), and therefore beta = 1.5.#66

A. , 5%

B. , 7.5%

C. , 12.5%

D. , 15%

Research has identified two systematic factors that affect U.S. stock returns. The factors are growth in industrial production and changes in long-term interest rates. Industrial production growth is expected to be 3%, and long-term interest rates are expected to increase by 1%. You are analyzing a stock that has a beta of 1.2 on the industrial production factor and .5 on the interest rate factor. It currently has an expected return of 12%. However, if industrial production actually grows 5% and interest rates drop 2%, what is your best guess of the stock's return?

A. , 15.9%

B. , 12.9%

C. , 13.2%

D. , 12%

B. , 12.9%


E[rnew] = 12% + (5% - 3%)(1.2) + (-2% - 1%)(.5) = 12.9%

27

There are two independent economic factors, M1 and M2. The risk-free rate is 5%, and all stocks have independent firm-specific components with a standard deviation of 25%. Portfolios A and B are well diversified. Given the data below, which equation provides the correct pricing model?

A. E(rP) = 5 + 1.12βP1 + 11.86βP2

B. E(rP) = 5 + 4.96βP1 + 13.26βP2

C. E(rP) = 5 + 3.23βP1 + 8.46βP2

D. E(rP) = 5 + 8.71βP1 + 9.68βP2

D. , E(rP) = 5 + 8.71βP1 + 9.68βP2

35 = 5 + 1.5 γ1 + 1.75 γ2; solve for γ1

γ1 = 20 - 1.1667γ2

20 = 5 + γ1 + .65γ2; sub in γ1

20 = 5 + 20 - 1.1667 γ2 + .65 γ2

γ2 = 9.68% γ1 = 8.71%
