Stock Market Facts

Historical Returns

One thing that makes stock market investing different from other types of investments is the tremendous amount of historical data that is available. We have performance data going back nine decades. Analyzing this data can increase investor confidence in probable outcomes in the future.

Betting on a sure thing?

In the nine decades since 1928, the following facts can be observed…

  • There has never been a 30-year stretch that didn’t produce a positive return.
  • There has never been a 20-year stretch that didn’t produce a positive return.
  • There has been only one 15-year stretch that failed to produce a positive return. It was during the Great Depression and the loss was -0.54%.
  • 10-year investment periods produced a positive return 95% of the time. The return for the worst 10-year period was -5%.
  • 5-year investment periods produced a positive return 89% of the time. The return for the worst 5-year period was -18%.
