the stock strategy does not defer the taxable gain at all. Equation (3.3) shows the after-tax return for an individual with a stock portfolio compris- ing 90 percent of the investment assets and a hedge fund with the remain- ing 10 percent of the assets.
In this scenario, the hedge fund return lowers the aggregate after-tax return because the higher tax rate on the hedge fund's pretax return lowers the af- ter-tax return below the stock after-tax return. Assume that the stocks and the hedge fund in the preceding example have standard deviation of return (also called volatility) of 20 percent annualized. However, the returns have a correlation of only 25 percent. Relying on the formula for portfolio volatility presented in answer 2.13, the standard deviation of return on the portfolio is given by equation (3.4):
(3.4) where A = Standard deviation on stock portfolio = 20%
B = Standard deviation on hedge fund = 20%
A,B = Correlation between the stock portfolio and the hedge fund 38 HEDGE FUND COURSE ccc_mccrary_ch03_35-58.qxd 10/6/04 1:41 PM Page 38
