Answer:
B; it offers an expected excess return of 1.8%
Explanation:
In this question, we apply the Capital Asset Pricing Model (CAPM) formula which is shown below
Expected rate of return = Risk-free rate of return + Beta × (Market rate of return - Risk-free rate of return)
For Stock A
The expected rate of return would be
= 5% + 1.2 × (9% - 5%)
= 5% + 1.2 × 4%
= 5% + 4.8%
= 9.8%
And, the expected return is 10%
So, the excess would be
= 10% - 9.8%
= 0.2%
For Stock B
The expected rate of return would be
= 5% + 1.8 × (9% - 5%)
= 5% + 1.8 × 4%
= 5% + 7.2%
= 12.2%
And, the expected return is 14%
So, the excess would be
= 14% - 12.2%
= 1.8%
