which of the following is NOT a key component of the
CAPM?
a. beta
b. diversifiable risk
c. the risk-free rate
d. the market risk premium
Ans : b. diversifiable risk
Explanation: CAPM model shows the relationship between the return on investment and systematic risk.
Formula:
where, ER = Expected Return of
Investment
Rf = risk-free rate
βi = beta of the investment
(Rm−Rf)=market risk premium .
So, by the above formula it is clear that risk-free rate, market risk premium & beta are key components of CAPM model.
Also note that beta is indicative of systematic risk. Systematic risk is the type of risk which cannot be diversified. Hence, we can conclude Diversifiable risk is not a component of CAPM model.
