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. Portfolio P consists of 50% X and 50% Y. 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) .

Stock A has a beta of 0.8, Stock B has a beta of 1.0, and Stock C has a beta of 1.2. Portfolio P has equal amounts invested in each of the three stocks. Each of the stocks has a standard deviation of 25%. The returns on the three stocks are independent of one another (i.e., the correlation coefficients all equal zero) . Assume that there is an increase in the market risk premium, but the risk-free rate remains unchanged. Which of the following statements is correct?


A) The required return of all stocks will remain unchanged since there was no change in their betas.
B) The required return on Stock A will increase by less than the increase in the market risk premium, while the required return on Stock C will increase by more than the increase in the market risk premium.
C) The required return on the average stock will remain unchanged, but the returns of riskier stocks (such as Stock C) will increase while the returns of safer stocks (such as Stock A) will decrease.
D) The required return on the average stock will remain unchanged, but the returns of riskier stocks (such as Stock C) will decrease while the returns on safer stocks (such as Stock A) will increase.

Since the market return represents the expected return on an average stock, that return has a certain amount of risk. As a result, there exists a market risk premium, which is the amount over and above the risk-free rate, which is required to compensate stock investors for assuming an average amount of risk.

B) False

Jane has a portfolio of 20 average stocks, and Dick has a portfolio of 2 average stocks. Assuming the market is in equilibrium, which of the following statements is correct?


A) Jane's portfolio will have less diversifiable risk and also less market risk than Dick's portfolio.
B) The required return on Jane's portfolio will be lower than that on Dick's portfolio because Jane's portfolio will have less total risk.
C) Dick's portfolio will have more diversifiable risk, the same market risk, and thus more total risk than Jane's portfolio, but the required (and expected) returns will be the same on both portfolios.
D) The expected return on Jane's portfolio must be lower than the expected return on Dick's portfolio because Jane is more diversified.

Which of the following statements is correct?


A) If a company with a high-beta stock merges with a low-beta company, the best estimate of the new merged company's beta is 1.0.
B) The beta of an "average stock," or "the market," can change over time, sometimes drastically.
C) If a newly issued stock does not have a past history that can be used as a basis for calculating beta, then we should always estimate that its beta will turn out to be 1.0. This is especially true if the company finances with more debt than the average firm.
D) During a period when a company is undergoing a change such as increasing its use of leverage or taking on riskier projects, the calculated historical beta may be drastically different than the "true" or "expected future" beta.

Risk aversion is a general dislike for risk, and a preference for certainty. If risk aversion exists in the market, then investors in general are willing to accept somewhat lower returns on less risky securities. Different investors have different degrees of risk aversion, and the end result is that investors with greater risk aversion tend to hold lower-risk (and therefore lower-expected-return) securities than investors who have more tolerance for risk.

B) False
