Consider historical data showing that the average annual rate of
return on the S&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 21% per year. Assume
these values are representative of investors' expectations for
future performance and that the current T-bill rate is 4%.
Calculate the utility levels of each portfolio for an investor with
A = 3. Assume the utility function is U = E(r) − 0.5 × Aσ2.
(Negative amounts should be indicated by a minus sign. Do not round
intermediate calculations. Round your answers to 4 decimal
places.)
