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 201 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 0.9% per month. (Do not round intermediate calculations.
