Consider historical data showing that the average annual rate of return on the 5&P 500 portfolio over the past 85 years has averaged roughly 8% more than the Treasury bill return and that the S&P 500 standard deviation has been about 33% per year. Assume these values are representative of investors' expectations for future performance and that the current T-bill rate is 3%. Calculate the utility levels of each portfolio for an investor with A= 2. Assume the utility function is U = E{r) - 8.5 = A2, (Do not round intermediate calculations. Round your answers to 4 decimal places. Negative amounts should be indicated by a minus sign. ) ) Answer is complete but not entirely correct.
