(8) Suppose you are given the following information regarding two stocks: A and B as follows: Era = 10.5% BA=0.7 Ers = 13% B B = 1.2 (a) What is the beta coefficient of a stock D with an expected rate of return of 12%? From your finding, what can you say about stock D? (b) Suppose you decided to invest 30% of your wealth in A, 30% in B, and 40% in the risk-free rate. What is the expected rate of return and the beta of the constructed portfolio? (c) Suppose you decided to invest 125% of your wealth in A and the remainder in the risk-free rate via borrowing at the risk- free rate. What is the expected rate of return and the beta of the constructed portfolio? (d) A portfolio fund manager, based on his fund's past perfor- mance, claims that the average rate of return on the fund is 15% and the fund beta is 0.875. How can we use the CAPM to assess the performance of this fund manager? fuomework Suppose that
