Answer:
No. Don't invest in the stock.
Step-by-step explanation:
First of all we have to calculate the return that we should expect from a company having beta of 1.28. To do so, CAPM should be used.
Ke = Risk-Free Rate + Beta (Market Risk Premium)
Putting values:
⇒ The Expected Return is = .045 + 1.28 (.077) = .14356 = 14.356%.
You are expecting the stock to generate a return of 9.6% but your analysis indicates that you should expect and demand a return of 14.35% from a stock having beta of 1.28. So, you should not but it.
Thanks!
