1. (15 points) Consider three securities with expected returns, standard deviation of returns and correla- tions between returns: Mi = 0.35, 01 = 0.5, P12 = P21 = 0.15; M2 = 0.30, 02 = 0.4, P23 P32 = -0.10; M3 = 0.20, 03 = 0.39, P13 = P31 = 0.10. Find the weights of the minimum variance portfolio. Find the expected return and standard deviation of this portfolio
