Standard Expected returns and standard deviations of three risky assets are as follows: Expected Correlations returns deviation A B C A 11% 30% 1 0.3 0.15 BC 14.5% 45% 0.3 1.0 0.45 9% 30% 0.15 0.45 1.0 a. Calculate the expected return and standard deviation of a portfolio of stocks A, B and C. Assume an equal investment in each stock. b. Compute the Sharpe ratio of a portfolio that has 30% in A, 30% in B and 40% in C. The risk-free interest rate is 4%. c. Assume a portfolio of asset B and C. Determine the weight in asset B, such that the total portfolio risk is minimized. (Hint: the minimum variance portfolio) Standard Expected returns and standard deviations of three risky assets are as follows: Expected Correlations returns deviation A B C A 11% 30% 1 0.3 0.15 BC 14.5% 45% 0.3 1.0 0.45 9% 30% 0.15 0.45 1.0 a.
