Assume that the Risky Portfolios return is 9.5% and its std. deviation is 13%. If the Risk Free rate is 2%, and your risk aversion A=4.5, what would be the optimal allocation between the Risky Portfolio and TBills? How would reductions in the Risk Aversion or increases in the TBill rate alter the findings? (Show your calculations, then discuss the implications of changes in 1-2 paragraphs).
