2} Find the optimal complete portfolio graphically using the client's indifference curve. Plot an indifference curve on the same graph you just created using the utility function formula from Chapter 6. To make things easier, you can use the same portfolio risk numbers from the table above and then calculate the expected return based on the values of utility (U) and risk aversion coefcient (A) in provided in the Excel spreadsheet. Plot the indifference curve AND the opportunity set of risky assets on the same graph. Next determine the optimal complete portfolio. You did this graphically above, but you need to calculate the precise composition of the optimal risky portfolio (recall ymaxU) and T-Bills (1-ymaxU)
