How do you calculate return of market index?

To calculate the return of a market index, you can use the formula:

[ \text{Return} = \frac{\text{Ending Value} - \text{Beginning Value}}{\text{Beginning Value}} \times 100 ]

This involves taking the difference between the ending value of the index and its beginning value, dividing that by the beginning value, and then multiplying by 100 to express it as a percentage. Additionally, you can account for any dividends or distributions if applicable, which can affect the total return.
