Math Problem Statement

Your investment over one year had a realized return of 8.65% and a dividend of $2.65. If the sale price was $42.58 per share, what was the cost of the investment, assuming you bought it at the beginning of the period?

Solution

To calculate the cost of the investment, we use the formula for the realized return:

Realized Return=Sale Price+DividendsCost PriceCost Price\text{Realized Return} = \frac{\text{Sale Price} + \text{Dividends} - \text{Cost Price}}{\text{Cost Price}}

Reorganize the formula to solve for the Cost Price:

Cost Price=Sale Price+Dividends1+Realized Return\text{Cost Price} = \frac{\text{Sale Price} + \text{Dividends}}{1 + \text{Realized Return}}

Given Data:

  • Realized Return: 8.65%=0.08658.65\% = 0.0865
  • Dividends: 2.652.65
  • Sale Price: 42.5842.58

Substituting values into the formula:

Cost Price=42.58+2.651+0.0865\text{Cost Price} = \frac{42.58 + 2.65}{1 + 0.0865}

Cost Price=45.231.0865\text{Cost Price} = \frac{45.23}{1.0865}

Cost Price41.63\text{Cost Price} \approx 41.63

Final Answer:

The cost of the investment was approximately $41.63 per share.
