I’m working on a business case study and need an explanation to help me study.

For stock and mutual fund investments only, research back to fair market value share price (or net asset value) one year ago, five years ago, and ten years ago. If you would have invested the same amount at those time intervals as you allocated to stock/mutual fund investments today, how much would you have? Assuming an average overall market return of 11% would have beaten the market? Show calculations to support.
