Consider three securities with expected returns 1 = 8% , 2 = 10% , 3 = 9% , standard deviations 1 = 0 . 15 , 2 = 0 . 05 , 3 = 0 . 12 and correlations 12 = 0 . 3 , 23 = 0 , 31 = 0 . 2 . Suppose that the risk-free return is R = 5% . Compute the weights in the market portfolio constructed from the three securities. Also compute the expected return and standard deviation of the market portfolio. Hint: The expected return and standard deviation are M = 0 . 0990 , M = 0 . 0465
