Answer:
subtracting the risk-free rate of return from the market rate of return
Explanation:
Market risk premium is the premium over the risk free rate that investors demand for holding a risky asset
Market risk premium = market rate of return - risk free rate
the higher the risk premium, the higher the return investors are demanding and the riskier the investment
for example if risk free rate is 5% , market rate of return in industry A is 10% while in industry B it is 20%
Market premium in A = 10% - 5% = 5%
Market premium in b = 20% - 5% = 15%
