O points Assume the retum on a market index represents the common factor and all stocks in the economy have a beta of 1. Firm-specific retums all have a standard deviation of 30% Suppose an analyst studies 20 stocks and finds that one-hall have an alpha of 3%, and one-hall have an alpha of -3%. The analyst then buys $1 milion of an equally weighted portfolio of the positive-alpha stocks and sells short $1 million of an equally weighted portfolio of the negative-alpha stocks a. What is the expected profit (in dollars), and what is the standard deviation of the analyst's profit? (Enter your answers in dollars not in millions. Round your answers to the nearest dollar amount.) Answer is complete but not entirely correct. Expected retum Standard deviation $ $ 134.164 134.164 6-1.
