A stock has an expected return of 11.85 percent, its beta is 1.24, and the expected return on the market is 10.2 percent. What must the risk-free rate be?

3.325%

Explanation:

The computation of the risk free rate of return is shown below:

As we know that

Expected rate of return = risk free rate of return + beta × (market rate of return - risk free rate of return)

11.85% = Risk Free Rate + ( 10.2% - Risk Free Rate) × 1.24

11.85% = Risk Free Rate + 12.648% - 1.24 × Risk Free Rate

0.24 × Risk Free Rate = 12.648 % - 11.85%

Risk Free Rate= (12.648 % - 11.85%) ÷  0.24

= 3.325%
