The Answer is a. The expected return on the portfolio is E(0.5X1 + 0.5X2) = 0.5E(X1) + 0.5E(X2)= 16.5%.
The variance of the portfolio's return is (0.5  20)2 + (0.5  32)2 + 2(0.5)2  0.80  20  32 = 612.
The standard deviation of the portfolio's return when 12 = 0.80 is therefore 24.74%.
b. Your choice of investment in stock 1, the portfolio, or stock 2 depends on your desired level of risk (variance of return). The higher the risk you choose, the higher will be the expected return.
