Question

Will the stock market crash? What history says

Short answer

Nobody can time a crash, and we do not forecast one. History shows how often and how deep they have been: since 1927 the S&P 500 has had 27 bear markets (falls of 20% or more), 13 of them since 1950. The median one fell -32.90% over 240 days and took 650 days from the low to regain the old high.

Today the index is -2.04% from its record close. Bear markets are dated here by the common rule: a 20% fall from a high, ending when the index rises 20% from the low.

What tends to come before a bear market

Bear markets have followed very different triggers: the 1929 crash, the oil shock of the 1970s, the dot-com bust in 2000, the financial crisis in 2008, the pandemic in 2020 and the inflation and rate shock of 2022. Several, but not all, overlapped with recessions. That is why we show the record and the signposts rather than a probability.

More questions

How often does the stock market crash?

By the 20% rule, the S&P 500 has entered a bear market 27 times since 1927, about once every 4 years on average, though they have come in clusters.

How long do bear markets last?

The median bear market took 240 calendar days from the high to the low. Getting back to the old high took a median of 650 days from the low.

What is the difference between a correction and a crash?

A correction usually means a fall of 10% to 20% from a high, and a bear market a fall of 20% or more. A crash is a very fast fall, such as October 1987 or March 2020.
