Please answer B and C

5. Portfolio Analysis Suppose there are two common stocks available for investment, stock A and stock B, with the following characteristics: Stock A Stock B Expected return: .10 .40 Standard deviation (o): .30 .20 Correlation coefficient (p): -.7 (A) Calculate the portfolio expected return and standard deviation of return for each of the following portfolios: Portfolio 1 2 3 4 Proportion in A 1 2/3 1/3 0 Proportion in B O 1/3 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".) 5.
