> Concept
The geometric average return formula calculates the average rate of return on an investment that is compounded over multiple periods.
> Formula
GAR = [ (1+r1)×(1+r2)×...(1+rn) ]1/n − 1
Return = [ Closing Value - Beginning Value ] / Beginning Value
> Calculation
GAR =
Year | Beginng Price | Return |
2017 | 40 |
= (45-40) / 40 = 12.50% |
2018 | 45 |
= (41-45) / 45 = -8.89 % |
2019 | 41 |
= (44-41) / 41 = 7.32% |
2020 | 44 | Since price of Beginning of 2021 not given |
GAR = [ (1+r1)×(1+r2)×...(1+rn) ]1/n − 1
= [ (1.1250) * ( 1 - 0.089 ) * (1.0732 ) ]1/3 - 1
= [ (1.1250) * (0.911) * (1.0732 ) ]1/3 - 1
= [ 1.0998959 ]1/3 - 1
= 1.03224 - 1
= 0.03225 or 3.23 % Answer
> Answer
The correct choice is Option 1 - 3.23 %.
Hope you understand the solution.
