Answer:
The answer is 5%
Explanation:
Solution
Given that:
A stock with a beta =2.0
The expected rate of return =21%
Market return turnout = 8%
Now,
Rf = risk free return
Rp = risk premium =Rm -Rf
β = 2.0
Thus
The expected return R = Rf +β *Rp
= Rf +β * (Rm -Rf)
R = Rf +2.0 (Rm -Rf)
=Rf + 2 times risk premium
So,
The market turns by 8%
R = Rf +2.0 (Rm -8%-Rf)
=Rf + 2 Rm-16%-2Rf
Then
The expected return is reduced by 16%
Hence,
21% -16% =5%
Therefore the expected rate of return on the stock is 5%
