Stock X has a beta of 0.7 and Stock Y has a beta of 1.7.Which of the following statements must be true, according to the CAPM?


A) Stock Y's realized return during the coming year will be higher than Stock X's return.

C) Stock Y's return has a higher standard deviation than Stock X.
D) If the market risk premium declines, but the risk-free rate is unchanged, Stock X will have a larger decline in its required return than will Stock Y.
E) If you invest $50, 000 in Stock X and $50, 000 in Stock Y, your 2-stock portfolio would have a beta significantly lower than 1.0, provided the returns on the two stocks are not perfectly correlated.

Which of the following statements is CORRECT?


A) The SML shows the relationship between companies' required returns and their diversifiable risks.The slope and intercept of this line cannot be influenced by a firm's managers, but the position of the company on the line can be influenced by its managers.
B) Suppose you plotted the returns of a given stock against those of the market, and you found that the slope of the regression line was negative.The CAPM would indicate that the required rate of return on the stock should be less than the risk-free rate for a well-diversified investor, assuming investors expect the observed relationship to continue on into the future.
C) If investors become less risk averse, the slope of the Security Market Line will increase.
D) If a company increases its use of debt, this is likely to cause the slope of its SML to increase, indicating a higher required return on the stock.
E) The slope of the SML is determined by the value of beta.
