There were 34 bear markets in the 115 years between 1900 and 2015 – on average they happened once every 3 years. More recently though, they have been less frequent.

Historically the S&P 500 has dropped by an average of 33% during bear markets and in over a third of those markets the drop was more than 40%. The good news is bear markets don’t last. The average lasts about a year with the shortest being 33 days (2020) and the longest being 694 days.
