Consider the data in the table below and answer the following questions: Utility Score Portfolio L Utility Score Portfolio M Utility Score Portfolio H Investor Risk Aversion (A) Er) =.07: =.05 E(r)=.09: O= E(r)= 13: o = 2 13-4x2x.22 =.0900 107 _x2x.052 = .0675.095x2x. P = 0800 x4x. 1 = -0700 13x4x.22 - 0500 1. The three risk aversion coefficients in the first column represent investors X, Y and Z. Which risky portfolio maximizes the utility of each investor? Give an explanation for your answer. Assume now that all the three risky portfolios L, M, H are uncorrelated (correlation is zero). In such situation, the variance of a portfolio is given by the following formula: W,2* 0,2 + W22* 02? + W,2* 032 2. Find the utility of each investor for an investment in a portfolio that holds L, M and H in equal proportion
