Answer:
B. 3.7%
Step-by-step explanation:
As per the CAPM, Expected return = Risk-free rate + Beta*(Expected return on the market - Risk-free rate)
Expected return% = 5% + 1.1% * (8% - 5%)
Expected return% = 5% + 1.1% *3%
Expected return% = 5% + 3.3%
Expected return% = 8.3 %
The alpha of the stock = Excess return
Excess return = 12% - 8.3%
Excess return = 3.7%
