She is pondering two portfolios, the S&P 500 and ahedge fund, as well as a number of 1-year strategies. (All ratesare annual and continuously compounded.) The S&P 500 riskpremium is estimated at 9% per year, with a SD of 18%. The hedgefund risk premium is estimated at 5% with a SD of 25%. The returnson both of these portfolios in any particular year are uncorrelatedwith its own returns in other years. They are also uncorrelatedwith the returns of the other portfolio in other years.
