Since 1926, the US stock market has rewarded investors with an annualized return of about 10%. But it’s important to remember that returns in any given year may be sky-high, extremely poor, or somewhere in between.

  • Annual returns came within two percentage points of the market’s long-term average of 10% in just seven of the past 96 years.
  • Yearly returns have ranged as high as up 54% and as low as down 43%.
  • Since 1926, annual returns have been positive 71 times and negative 25 times.
