Consider portfolios of three assets with means given by vector 0.06 =| 0.08 0.12 and covariance given by 0.03-0.01 0.00 = -0.01 0.04 0.01 0.00 0.01 0.06 (a) Find the mean and the variance of the minimum variance portfolio (b) Suppose we want to achieve an expected return of 10% by investing in these assets. How do we achieve this efficiently? find the risk of this portfolio. (c) Suppose = 4%, give the weights of the tangency portfolio. (d) Suppose we desire to achieve an expected return of 10%, by in- vesting in the risk free and the risky assets, what is the risk of the efficient portfolio in this case?
