Final answer:
The geometric average return of Western Hill Farms' common stock over the past five years is -23.66%.
Step-by-step explanation:
To find the geometric average return of Western Hill Farms' common stock over the past five years, we need to calculate the product of all the individual returns and then take the fifth root of that product.
To calculate the product, we multiply each return as a decimal:
- 16.3% = 0.163
- 7.2% = 0.072
- 11.8% = 0.118
- -3.6% = -0.036
- 9.9% = 0.099
The product is: (0.163) * (0.072) * (0.118) * (-0.036) * (0.099) = -0.00002067.
Finally, we take the fifth root of the product to find the geometric average return: (-0.00002067)^(1/5) = -0.2366 = -23.66%.
