You have a portfolio P that consists of 50% Stock X and 50% Stock Y. Stock X has a beta of 0.7 and Stock Y has a beta of 1.3. The standard deviation of each stock's returns is 20%. The stocks' returns are independent of each other, i.e., the correlation coefficient, r, between them is zero. Given this information, which of the following statements is CORRECT?


A) The required return on Portfolio P is equal to the market risk premium (rM − rRF) .
B) Portfolio P has a beta of 0.7.
C) Portfolio P has a beta of 1.0 and a required return that is equal to the riskless rate, rRF.
D) Portfolio P has the same required return as the market (rM) .
E) Portfolio P has a standard deviation of 20%.

Your friend is considering adding one additional stock to a 3-stock portfolio, to form a 4-stock portfolio. She is highly risk averse and has asked for your advice. The three stocks currently held all have b = 1.0, and they are perfectly positively correlated with the market. Potential new Stocks A and B both have expected returns of 15%, are in equilibrium, and are equally correlated with the market, with r = 0.75. However, Stock A's standard deviation of returns is 12% versus 8% for Stock B. Which stock should this investor add to his or her portfolio, or does the choice not matter?


A) Stock A.
B) Stock B.
C) Neither A nor B, as neither has a return sufficient to compensate for risk.
D) Add A, since its beta must be lower.
E) Either A or B, i.e., the investor should be indifferent between the two.
