Answer:
SDA Corp. Stock Alpha is 3.80%
Step-by-step explanation:
If we calculate the expected return on SDA Corp. stock through Capital asset pricing model, we will get:
CAPM = Risk Free Rate + (Return on market portfolio - Risk free rate) * Beta
CAPM = Rf + (Rm - Rf)*β
CAPM = 12% + (19% - 12%)*1.40
CAPM = 12% + 9.8%
CAPM = 21.8%
The expected return on stock through CAPM is 21.8%, whereas, the expected return of SDA Corp. common stock is 18%. Therefore, the stock Alpha is 21.8% - 18% = 3.80%
