Answer:
5%
Explanation:
In order to compute the abnormal return first we have to find out the actual return which is shown below:
Actual return is
= ($21 - $18 + 1.32) ÷ ($18) × 100
= 24%
And, the expected return is
= Risk free rate of return + Beta × (Market rate of return - risk free rate of return
= 7% + 1.20 × (17% - 7%)
= 7% + 1.20 × 10%
= 7% + 12%
= 19%
So, the stock abnormal return is
= 24% - 19%
= 5%
