Bear Market Statistics (2026)

A bear market is conventionally a decline of 20% or more from a recent peak. By Ned Davis Research's count, cited by Hartford Funds, the S&P 500 has had 27 bear markets since 1928, against 28 bull markets (see the table below). That works out to roughly one bear every 3.5 years.

The count depends on the definition, which is worth knowing. A stricter closing-basis rule yields a cleaner list of 15 major bears from 1929 to 2022. Both are valid; they just draw the 20% line slightly differently, so do not be surprised when sources say 27, 26, or 15.

The 20% threshold is a convention, not a law of nature. A drop of 10% to 20% is a correction; 20% or more from the peak is a bear market. Some data providers require the decline to persist for at least a month or use intraday lows, which is why the exact tally moves around.

The 1990 episode is the classic edge case: the S&P 500 bottomed at -19.9%, one tick above the line, yet it is almost always counted as a bear market. Precision matters less than the pattern, which is that sizable drawdowns are a recurring, normal feature of investing.

The typical bear market has been painful but survivable. Since 1928 the average decline has been about 35% (-35.24% precisely), and the average length has been 289 days, or roughly 9.6 months, according to Hartford Funds and Ned Davis Research.

Averages hide a wide spread. The mildest bears clipped stocks about 20-22%, while the 1929-32 collapse erased 86% and the 2007-09 financial crisis took 57%. Most bears cluster in the -20% to -40% range, with a handful of generational disasters pulling the average down.

The single most important bear-market statistic is the asymmetry with bull markets. Bears average a 35% loss over about 9.6 months; bulls average a 112% gain over 988 days, or 2.7 years (see the chart and table below). The upside has been more than three times larger and lasted about three times longer.

That is why, across the last 95 years, stocks have been rising roughly 78% of the time. Bear markets feel dominant while you are in one, but they occupy only about a fifth of market history. Patience, not timing, has captured the gap.

On a long-run average, a bear market has arrived about every 3.5 years since 1928. But the cadence has slowed markedly over time (see the table below). Between 1928 and 1945 there were 12 bears, roughly one every 1.5 years, a reflection of the Depression and its violent aftershocks.

Since 1945 there have been 15 bears, about one every 5.1 years. Better policy tools, deposit insurance, and circuit breakers have not abolished bear markets, but they have made the outright crashes of the 1930s far rarer. Expect one every few years, not every year.

Hitting bottom is only half the story; getting back to even is the other half. On average the S&P 500 has taken about 2.5 years (2.4 years at the median) to return to its prior peak, per Ned Davis Research data cited by the Motley Fool (see the chart below).

The tail is long. Ordinary bears recovered in one to two years, but the generational ones did not: 1929-32 took about 25 years to a new closing high, 1937 took nearly 9, and both 2000 and 2007 took over 4. Those outliers are why disciplined dollar-cost averaging beats waiting for an all-clear.

Here is the closing-basis roll call of the 15 major S&P 500 bear markets, from the 1929 crash to the 2022 selloff (see the table and chart below). It captures the peak, the trough, the percentage lost, how long the decline ran, and how long it took to reclaim the old high.

The pattern that jumps out is variety. Declines ranged from -19.9% (1990) to -86.2% (1929-32); durations ran from 33 days (2020) to over three years (1946-49). No two bears look alike, which is exactly why forecasting their timing has proven so unreliable.

Three bears stand apart for depth. The 1929-32 crash remains the benchmark disaster at -86.2%, followed by the 2007-09 global financial crisis at -56.8% and the 1937-38 relapse at -54.5%. The 1973-74 (-48.2%) and 2000-02 dot-com (-49.1%) bears round out the roughly-half-your-money club.

What these share is not just a market event but an economic one: a banking collapse, a credit crisis, or a burst valuation bubble tied to recession. The deepest, longest bears almost always coincide with real economic damage, not just a change in sentiment.

The 2020 pandemic bear rewrote the speed record. The S&P 500 fell 33.9% in just 33 trading days, the fastest 30%-plus drop from a record high in history, then recovered its losses within about five months by August 2020.

It is the exception that proves the rule about timing. An investor who sold in the March panic would have needed to buy back in almost immediately to avoid missing a historic rebound. The recovery came before the pandemic was anywhere near over, which is typical: markets turn before the news does.

Not all bears are equal, and whether a recession shows up is the biggest tell. Bear markets that coincide with a recession have averaged roughly a 35% decline and about 18 months, while bears without a recession have been far milder, around -22% and only about three months (see the table below).

That distinction matters because there have been 27 bear markets since 1928 but only 15 recessions. Roughly half of bears were sentiment- or valuation-driven scares that resolved quickly, per the CFA Institute's bear-market work. The dangerous ones are the recessionary bears.

Most declines never become bear markets. A 10% correction has historically arrived about every 1.8 years, a 15% drop about every 2.5 years, and a full 20% bear only about every 4 years (see the table below). Of 27 corrections since November 1974, only six turned into bears.

Even in years the S&P 500 finished higher, it has averaged an intra-year drop of about 14% since 1980. Volatility is the price of admission, not a malfunction. Knowing that a double-digit dip is a near-annual event makes it far easier to sit through one.

The cruelest fact about bear markets is where the best days live. About 42% of the S&P 500's strongest days in the last 20 years occurred during a bear market, and another 36% happened in the first two months of the new bull, according to Hartford Funds.

Because those explosive up days cluster right around the bottom, an investor who sells to dodge the pain routinely misses the rebound. Missing just a handful of the best days over decades has historically cut long-run returns roughly in half. Time in the market beats timing it.

The pre- and post-war eras are almost different markets. The 1928-1945 window produced 12 bear markets in 17 years, a bear roughly every 18 months, driven by the Depression, deflation, and a fragile, uninsured banking system.

The postwar decades calmed considerably: 15 bears since 1945, about one every five years. The lesson is not that stocks got safe, but that the character of risk shifted from frequent depression-era collapses to occasional, sharper shocks like 1987, 2008, and 2020.

The statistics point to one conclusion: bear markets are inevitable, survivable, and terrible to trade around. If you invest for decades you should expect to live through perhaps a dozen of them, each averaging a 35% drop and a couple of years to recover, and each ultimately followed by a bull market that gained far more.

The practical playbook is boring on purpose: hold an emergency fund so you are never forced to sell at the bottom, keep contributing through the decline (a bear market is a discount), stay diversified, and match your stock allocation to a time horizon long enough to ride out a multi-year recovery. The investors who did worst were not the ones who bought at the top; they were the ones who sold at the bottom.
