__._.. __ ____ _____ .. ___ 1"""" (a) Estimate the expected return of assets A and B according to the "CSOM" portfolio manager and according to the \"HISTORICAL" portfolio manager. Compare the estimates. (b) Using the previous estimates for expected returns and the information provided in the introduction, (d) nd the Mean Variance Efcient Portfolio [h-TVEP) of the "CSOM" portfolio manager. Also, find the lt-'IVEP of the "HISTORICAL" portfolio manager. Briefly comment on the differences between the two MVEP portfolios. (Note: you should use the Excel solver function to do this. It will be very easy if you use the le "Example Optimal CAL.xls\" that is posted on the course webpage. Just plug in the new numbers there and maximize the Sharpe Ratio following the instructions there) Find the expected return. the standard deviation and the Sharpe Ratio of the lN-IVEP of each manager that you found in the previous question. (Note: if you used the Excel le \"Example Optimal CALxls" to answer the previous question= you already have the answer to this question feel free to use those number here) (BONUS: Do you think it makes sense to compare the two lt-TVEP? If yes, why? If not= why not?) Assume that the coefcient of risk aversion of each portfolio manager is A = 15. \"that is the optimal global portfolio of the "CSOM" portfolio manager and of the "HISTORICAL" portfolio manager? Find what proportion of their funds should each portfolio manager invest on the riskfree asset and what proportion should be invested in their RIVER Briey comment on the differences in the proportion invested in each asset by the two portfolio managers
