The 2020 bear market was the fastest bear market in S&P 500 history.
The S&P 500 entered bear-market territory on March 12, 2020, after falling at least 20% from its February 19 record close. The decline was driven by the economic shock and uncertainty created by the COVID-19 pandemic, including travel restrictions, business closures, supply disruptions, and fears of a deep recession.
The index’s fall from its February peak to its March 23 low took only about one month, making the episode unusually rapid. Governments and central banks responded with large fiscal and monetary measures, while investors later began pricing in economic reopening and vaccine development.
The crash is often confused with the 2020 recession itself. They were closely connected but not identical: the stock market began recovering before economic activity had fully returned. The episode also showed that a bear market can be extremely short in duration even when the underlying economic shock is severe.
