Required:
a. Suppose you hold an equally weighted portfolio of 100 stocks with the same alpha, beta, and residual standard deviation as
Waterworks. Assume the residual returns (the e terms in Equations 20.1 and 20.2) on each of these stocks are independent of each
other. What is the residual standard deviation of the portfolio? (Round your percentage answer to 2 decimal places.)
Residual standard deviation
b. Recalculate the probability of a loss on a market-neutral strategy involving equally weighted, market-hedged positions in the 100
stocks over the next month. Assume the risk-free rate is 0.1% per month, (Do not round intermediate calculations. Round your
percentage answer to 5 decimal places.)
