B) Stock Y's realized return during the coming year will be higher than Stock X's return.
C) If the expected rate of inflation increases but the market risk premium is unchanged, the required returns on the two stocks should increase by the same amount.

Which of the following statements is CORRECT?


A) If a company's beta doubles, then its required rate of return will also double.
B) Other things held constant, if investors suddenly become convinced that there will be deflation in the economy, then the required returns on all stocks should increase.

Stock HB has a beta of 1.5 and Stock LB has a beta of 0.5. The market is in equilibrium, with required returns equaling expected returns. Which of the following statements is CORRECT?


A) If expected inflation remains constant but the market risk premium (rM − rRF) declines, the required return of Stock LB will decline but the required return of Stock HB will increase.
B) If both expected inflation and the market risk premium (rM − rRF) increase, the required return on Stock HB will increase by more than that on Stock LB.
C) If both expected inflation and the market risk premium (rM − rRF) increase, the required returns of both stocks will increase by the same amount.
D) Since the market is in equilibrium, the required returns of the two stocks should be the same.
