Answer:
Difference between the required rates of return of A and B = 2.3625%
Explanation:
Using the CAPM, we can calculate the required/expected rate of return on a stock. This is the minimum return required by the investors to invest in a stock based on its systematic risk, the market's risk premium and the risk free rate.
The formula for required rate of return under CAPM is,
r = rRF + Beta * (rM - rRF)
Where,
r of A = 0.0425 + 0.7 * (0.11 - 0.0425)
r or expected rate of return of A = 0.08975 or 8.975%
r of B = 0.0425 + 1.05 * (0.11 - 0.0425)
r or expected rate of return of B = 0.113375 or 11.3375%
Difference between the required rates of return of A and B = Required rate of return of B - Required rate of return of A
Difference between the required rates of return of A and B = 11.3375% - 8.9750%
Difference between the required rates of return of A and B = 2.3625%
