Answer:
The risk free rate is 6.50%
Explanation:
The required rate of return is the minimum return that investors demand/expect on a stock based on the systematic risk of the stock as given by the beta. The expected or required rate of return on a stock can be calculated using the CAPM equation.
The equation is,
r = rRF + Beta * (rM - rRF)
Where,
As we know the figures for r, Beta and rM, we will input these figures in the equation to calculate risk free rate.
Let risk free rate be x.
0.135 = x + 1.4 * (0.115 - x)
0.135 = x + 0.161 - 1.4x
0.135 - 0.161 = x - 1.4x
-0.026 = -0.4x
-0.026 / -0.4 = x
x = 0.065 or 6.50%
r = 0.1475 or 14.75%
