7. Portfolio Analysis Suppose there are two common stocks available for investment, stock A and stock B, with the following characteristics: Expected return: Standard deviation (a): Correlation coefficient (p): Stock_B . 40 .20 . 10 . 30 (a) Calculate the portfolio expected return and standard deviation of return for each of the following portfolios: 1 2/3 1/3 0 2/3 1 (b) Sketch (this does not have to be a work of art, but try to be careful) the feasible set of all portfolios composed of A and B. (c) Suppose that there is now the opportunity to borrow or lend at the risk-free rate of return, which is 10%. Show on your sketch in part (B) how this changes the investment opportunities available. (Be sure to clearly label this "PART c" .) (d) Assume you are a rational investor and can invest in stock A, stock B, the risk-free security, or any combination thereof. Further assume that you have $150,000 and decide to invest $60,000 in the risk-free security and $90,000 in risky securities. Approximately how much money will you invest in Security B? Briefly explain how you arrived at your answer. 7.
