Answer: C) SDA Corp. stock's alpha is -4.5%
Step-by-step explanation:
Calculate the required return using the Capital Asset Pricing Model.
= risk free rate + beta ( market return - risk free rate)
= 6% + 1.5 (13% - 6%)
= 6% + 10.5%
= 16.5%
The expected return on the stock is 12% yet the required return is 16.5%. This means that this stock is overpriced because it is giving a return less than what it should be giving.
The alpha is therefore;
= Expected return - Required return
= 12% - 16.5%
= - 4.5%
