Which statement about the CAPM is most accurate?
A stock's required return depends on its systematic risk. Under the CAPM, diversifiable risk can be removed by holding a diversified portfolio, so the market does not reward it. Beta captures the non-diversifiable risk that determines the risk premium, not total standard deviation.
- AInvestors are rewarded for bearing diversifiable risk.
- BA stock's required return depends on its systematic risk.Correct
- CRequired return depends on a stock's total standard deviation.
Explanation
In the CAPM, diversifiable (unsystematic) risk can be eliminated in a diversified portfolio, so it earns no premium. Only systematic risk, measured by beta, determines required return. Total standard deviation includes diversifiable risk and is not the pricing measure.
