[4 marks] (b) Compute the non-systematic risk in terms of standard deviation for Fund A and Fund B. [2 marks] (c) Rank the performance of the funds based on the Sharpe ratio and the Treynor ratio. Are the two performance rankings consistent? If not, explain the most likely reason for this difference. [4 marks] (d) The manager has the utility function, U = E(r)-1/2 A*sigma^2.
