Answer: 9%
Step-by-step explanation:
The market risk premium given an expected return on a security of 18.7%, a stock beta of 1.3, and a risk-free interest rate of 7% will be calculated as:
Expected return = risk free rate + Beta × market risk premium
= (18.7% - 7%)/1.3
= (0.187 - 0.07)/1.3
= 0.117/1.3
= 0.09
= 9%
The market risk premium is 9%.
