) 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 on each of these stocks are independent of each other. What is the residual standard deviation of the portfolio? (Round your answer to 1 decimal place.) b. Calculate 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 0.6% per month. ( Do not round intermediate calculations. Enter your answer as percent rounded to 5 decimal places.)
