How to Invest During a Bear Market

There's something counterintuitive about investing in a bear market. As traders jump into a plunging market, they must be willing to embrace the likelihood of further losses before seeing potentially greater returns when the bear finally yields to the bull. It's a hard pill to swallow, and many investors just can't do it. As a result, they can miss out on the opportunity to buy low.

Everyone's heard the saying "Don't try to catch a falling knife." As wise as this may sound, it doesn't help much when the bear rears its ugly head. That's because, in a bear market, it could be raining knives for quite some time. There's an upside, though: A falling stock is only a proverbial knife if you catch it the wrong way.

When markets fall, strategic traders want to catch as many high-value—yet discounted—stocks as possible without hurting themselves in the process. So how can they position themselves for the next bull market without getting mauled?

It might help to better understand the basics of tracking this type of market.

What is a bear market?

A bear market is a fundamentally-driven market decline of 20% or more. These often coincide with a weakening economy, massive liquidation of securities, and widespread investor fear and pessimism.

How long does an average bear market last?

According to CFRA data on the S&P 500® index, the shortest bear markets lasted about three months in 1987 and 1990. This excludes the tariff-related plunge in April 2025, which technically brought the major indexes into bear-market territory, but only for three trading days.

The longest bear market lingered for three years, from 1946 to 1949. Taking the past 12 bear markets into consideration, the average length of a bear market is about 14 months.
