CHAPTER 2—RISK AND RETURN: PART I
89. Stock LB has a beta of 0.5 and Stock HB has a beta of 1.5. The market is in equilibrium, with required returns
equaling expected returns. Which of the following statements is CORRECT?
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.
If both expected inflation and the market risk premium (rM − rRF) increase, the required returns of both stocks
will increase by the same amount.
Since the market is in equilibrium, the required returns of the two stocks should be the same.
If expected inflation remains constant but the market risk premium (rM − rRF) declines, the required return of
Stock HB will decline but the required return of Stock LB will increase.
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.

90. Portfolio P has equal amounts invested in each of the three stocks, A, B, and C. 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. 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?
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.
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.
The required returns on all three stocks will increase by the amount of the increase in the market risk premium.
The required return on the average stock will remain unchanged, but the returns on riskier stocks (such as
Stock C) will decrease while the returns on safer stocks (such as Stock A) will increase.
The required return of all stocks will remain unchanged since there was no change in their betas.
