Page 284 Conceptual M/C Chapter 8: Risk and Return
89. 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 returns on all three stocks will increase by the amount
of the increase in the market risk premium.
e. 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.
90. 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.
c. If a company’s beta were cut in half, then its required rate of
return would also be halved.
d. If the risk–free rate rises by 0.5% but the market risk premium
declines by that same amount, then the required rates of return on
stocks with betas less than 1.0 will decline while returns on stocks
with betas above 1.0 will increase.
e. If the risk–free rate rises by 0.5% but the market risk premium
declines by that same amount, then the required rate of return on an
average stock will remain unchanged, but required returns on stocks
with betas less than 1.0 will rise.
91. Assume that the risk-free rate is 6% and the market risk premium is 5%.
Given this information, which of the following statements is CORRECT?
a. An index fund with beta = 1.0 should have a required return of 11%.
b. If a stock has a negative beta, its required return must also be
negative.
c. An index fund with beta = 1.0 should have a required return less
than 11%.
d. If a stock’s beta doubles, its required return must also double.
e. An index fund with beta = 1.0 should have a required return greater
than 11%.
