Answer: 16.33%
Explanation:
With the details given, the best method of Calculating the expected rate of return is the Capital Asset Pricing Model (CAPM).
The formula is,
Er = Rf + b(Rm - Rf)
Where,
Er is expected return
Rf is the risk free rate
b is beta
Rm - Rf is the Market Premium
Er = 3.87% + 1.38(9.03)
= 3.87% + 12.4614%
= 16.33%
The model accounts for inflation by including the risk free rate which is already adjusted for inflation.
