Answer:
Expectation of rate of return on the stock is 16.64%
Step-by-step explanation:
Ke=Rf+beta(Mrp-Rf)
Rf is unknown
Mrp is 15%
Ke is 19.5%
beta is 1.3
19.5%=Rf+1.3(15%-Rf)
19.5%=Rf+19.5%-1.3Rf
19-5%-19.5%=Rf-1.3Rf
0%=-0.3Rf
Rf=0%/-0.3
Rf=0%
By substituting the value of Rf in the original formula ,we can now calculate Ke when Mrp is 12.80%,beta is 1.3 Rf is 0%
Ke=0%+1.3(12.80%-0%)
Ke=0%+16.64%+0%
Ke=16.64%
