e.The degree of total leverage (DTL) is equal to the DFL divided by the degree of
operating leverage (DOL).
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.
Which of the following statements is CORRECT?
a.The slope of the security market line is equal to the market risk premium.
b.Lower beta stocks have higher required returns.
c.A stock’s beta indicates its diversifiable risk.
d.Diversifiable risk cannot be completely diversified away.
e.Two securities with the same stand-alone risk must have the same betas.
Suppose you are analyzing two firms in the same industry. Firm A has a profit margin
of 10% versus a profit margin of 8% for Firm B. Firm A’s total debt to total capital ratio
[measured as (Short-term debt + Long-term debt)/(Debt + Preferred stock + Common
equity)] is 70% versus one of 20% for Firm B. Based only on these two facts, you
cannot reach a conclusion as to which firm is better managed, because the difference in
debt, not better management, could be the cause of Firm A’s higher profit margin.
a.True
