Answer:
Economy type Expected return Weightage Weighted Average
Boom 14% 10% 0.14*0.10= 0.014
Normal 9% 85% 0.85*0.090=.0765
Recession -8% 5% -0.08*0.05=-0.004
Add all the weigtage averages (0.014+0.0765-0.004)= 0.0865= 8.65%
The expected rate of return of the stock is 8.65%
Explanation:
In this question we need to find the weighted average returns, we know the expected return during a boom, normal and recession and we need to use the probabilities of boom, normal and recession as the weights, so the event which is most likely to happen will have the most weightage, this way we can find the expected return of the stock. There is a 85% chance that there will be a normal economy so the expected return in a normal economy will have the highest weightage.
