Answer: Stock of D is correctly priced at 10.08%
( for the beta of Stock A and D, I guessed you meant 0.89 and 0.80 respectively as opposed to 89 and 80 you put, so i corrected and solved accordingly.)
Step-by-step explanation:
Expected return = Rf + beta ( Rm - Rf )
Rf =Risk free return = 3.6
Rm-Rf = Market risk premium = 8.1%
A) Stock Beta , Expected Return= 0.89, 7.83%
Expected return = 3.6 + 0. 89 (8.1) = 10.809%-- its over priced
B) Stock Beta , Expected Return= 1.52 12.59%
Expected return = 3.6 + 1.52(8.1) = 15.912%---- its over priced
B) Stock Beta , Expected Return= 1.25 11.27%
Expected return = 3.6 + 1.25(8.1) = 13.725 %--- its overpriced
c) Stock Beta , Expected Return= 1.27 14.50%
Expected return = 3.6 + 1.27(8.1) = 13.887%---- Its underpriced
d) Stock Beta , Expected Return= 0.80 10.08%
Expected return = 3.6 + 0. 80(8.1) = 10.08%---- Correctly priced
