A fund manager invests in two assets: Asset A and Asset B. Assume the CAPM model is correct and suppose the risk-free rate is 0% and the market risk premium (i.e. expected excess return of the market) is 6%. Use the following information about Asset A and B to answer the questions: Portfolio weight Beta 1.2 0.8 Asset A 0.75 Asset B 0.25 Realized return in this period 6% 3% (a) What is the fund manager's portfolio return in this period? (b) What is the fund manager's portfolio beta in this period? If the realized market return in this period is 4%, what is the fund manager's portfolio alpha in this period? c) Suppose the expected return of Asset A in the next period is 9% and Asset B is 6%. What is the fund manager's expected alpha? What recommendation would you give to the manager to increase her alpha?
