Assume the return on a market index represents the common factor
and all stocks in the economy have a beta of 1. Firm-specific
returns all have a standard deviation of 50%.
Suppose an analyst studies 20 stocks and finds that one-half have
an alpha of 4.6%, and one-half have an alpha of –4.6%. The analyst
then buys $1.2 million of an equally weighted portfolio of the
positive-alpha stocks and sells short $1.2 million of an equally
weighted portfolio of the negative-alpha stocks.
a. What is the expected return (in dollars), and
what is the standard deviation of the analyst’s profit?
(Enter your answers in dollars not in millions.
Do not round intermediate calculations. Round your answers
to the nearest dollar amount.)

Standard deviation:
b-1. How does your answer for standard deviation
change if the analyst examines 50 stocks instead of 20?

Consider two stocks, Stock D, with an expected return of 20 percent and a standard deviation of 36 percent, and Stock I, an international company, with an expected return of 6 percent and a standard deviation of 16 percent. The correlation between the two stocks is –0.01. What are the expected return and standard deviation of the minimum variance portfolio? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places.) Expected Return? Standard deviation?
Suppose that the index model for stocks A and B is estimated from excess returns with the following results: RA = 2.5% + 0.95RM + eA RB = –1.8% + 1.10RM + eB σM = 27%; R-squareA = 0.23; R-squareB = 0.11 Assume you create a portfolio Q, with investment proportions of 0.50 in a risky portfolio P, 0.30 in the market index, and 0.20 in T-bill. Portfolio P is composed of 60% Stock A and 40% Stock B. a....
