"That's because in the first few years, the change in the stock's price might have been from $10 to $11.50, and later from $25 to $28.75, and later still from $75 to $86.25. So the absolute changes will look small at the beginning, and will look large later on. But it's really just been a steady 15% increase from year to year. (Remember, an investor should be just as happy with a total 50% return from $20 to $30 as from $100 to $150. Investment-wise, percentage-wise, it's the same thing.)"
