A Assume analysts provide the following types of information. Assume short sales are allowed. Stock Mean Return Standard Deviation 6% 6% B 7% 8% C 9% 12% risk free rate 2% The pairwise coefficient of correlation between all three stocks is 0.4, i.e. PABEPAC=PBC=0.04. a) What the rate of return and the standard deviation of an equal weighted portfolio consist of all three stocks? [2] b) What are the weights of A and B in the portfolio consist of A and B only with highest Sharpe ratio? What is the Sharpe ratio of the portfolio? [4] C) Find the weights of stock A, B and C in the global minimum variance portfolio. [4]
