Greta has risk aversion of A = 4 when applied to return on wealth over a one-year horizon. She is pondering two portfolios, the S&P 500 and a hedge fund, as well as a number of 4-year strategies. (All rates are annual and continuously compounded.) The S&P 500 risk premium is estimated at 10% per year, with a standard deviation of 22%. The hedge fund risk premium is estimated at 14% with a standard deviation of 37%. The returns on both of these portfolios in any particular year are uncorrelated with its own returns in other years. They are also uncorrelated with the returns of the other portfolio in other years. The hedge fund claims the correlation coefficient between the annual return on the S&P 500 and the hedge fund return in the same year is zero, but Greta is not fully convinced by this claim.
