A stock has a required return of 16.00%, the risk-free rate is
8.20%, and the market risk premium is 12.20%.
a) What is the stock's beta?
b) If the market risk premium changes to 5.50%, what would happen
to the stock's required rate of return? Assume that the risk-free
rate and the beta remain unchanged.
a) Required return = Risk-free rate + Beta(Market risk premium)
0.1600 = 0.0820 + Beta(0.1220)
Beta = (0.1600 - 0.0820) / 0.1220
Beta = 0.64
b) Required return = Risk-free rate + Beta(Market risk premium)
Required return = 0.0820 + 0.64(0.0550)
Required return = 0.1172 or 11.72%
