Stock Market Crash Statistics (2026)

Updated July 2026

The short answer

The five biggest US market crashes since 1929 wiped out between 34% and 89% of index value. The 1929 crash was the worst, with the Dow down about 89% into 1932 and a recovery that took 25 years. The 2008 financial crisis cut the S&P 500 by 57%, and the 2020 COVID crash fell 34% in just 33 days, the fastest bear market ever, but recovered within five months. On average, US bear markets since 1928 have fallen about 35% and lasted roughly 9.6 months, and the market has recovered its prior peak every single time.

Key takeaways
  • The 1929 crash was the deepest: the Dow fell about 89% from its September 1929 peak to its July 1932 low and did not regain that peak until November 1954, a 25-year wait (Federal Reserve History).
  • Black Monday, October 19, 1987, remains the largest single-day percentage drop in modern history: the Dow fell 508 points, or 22.6%, in one session (Federal Reserve History).
  • The dot-com bust took the Nasdaq down about 78% (peak 5,048 in March 2000 to roughly 1,114 in October 2002), and the Nasdaq did not set a new high again for 15 years, until 2015.
  • The 2008 financial crisis cut the S&P 500 by 57% from its October 2007 peak to its March 2009 low of 666, and the index took until March 2013, about 5.5 years, to recover (Wikipedia).
  • The 2020 COVID crash was the fastest ever: the S&P 500 fell 34% in 33 calendar days, entered a bear market in 16 trading sessions, then recovered to a new high within about five months.
  • Across 27 bear markets since 1928, stocks have fallen about 35% on average over roughly 9.6 months, yet the market has recovered its prior peak after every one, taking about 2.5 years on average (Hartford Funds).

The big picture

Five crashes define modern US market history: 1929, 1987, 2000, 2008, and 2020. They ranged from a one-day panic to a three-year grind, and their peak-to-trough losses ran from 34% to about 89% of index value (see the table below).

The pattern across all of them is the same in the end: every crash was eventually recovered. What differed wildly was the wait, from about five months after the 2020 low to a full 25 years after the 1929 peak.

1929: The Great Crash

The 1929 crash is the benchmark for catastrophe. After peaking at 381 on September 3, 1929, the Dow fell on Black Thursday (October 24), Black Monday (October 28, down 12.8%), and Black Tuesday (October 29, down 11.7%), then kept sliding for nearly three more years to a low of 41 in July 1932, an 89% collapse.

The causes were rampant speculation, buying stock on thin margin, and a fragile banking system that the crash helped tip into the Great Depression. Investors who bought at the 1929 top did not see that price level again until November 1954, according to Federal Reserve History.

1987: Black Monday

October 19, 1987 produced the single worst day in modern market history: the Dow fell 508 points, or 22.6%, in one session, a drop with no single obvious news trigger. Worldwide losses were estimated near $1.71 trillion, and computer-driven program trading and portfolio insurance amplified the selling.

Yet 1987 is also the model for a fast rebound. The market clawed back most of the loss within days, the Dow still finished 1987 slightly positive on the year, and it fully recovered its pre-crash peak within about two years, per Federal Reserve History.

2000: The dot-com bust

The technology bubble burst in March 2000. The Nasdaq Composite peaked at 5,048 on March 10, 2000, then fell about 78% to roughly 1,114 by October 2002 as internet valuations with no earnings collapsed. The broader S&P 500 fell about 49% over the same stretch.

This was a slow-motion crash, not a one-day panic, spread over 30 months. Recovery was uneven: the S&P 500 regained its high by 2007, but the Nasdaq did not set a new record for 15 years, not until 2015, a reminder that concentrated, overvalued sectors take longest to heal.

2008: The financial crisis

The 2007-2009 crash was the worst since the 1930s. From its October 9, 2007 peak of 1,565, the S&P 500 fell 57% to an intraday low of 666 on March 6, 2009, driven by subprime mortgages, over-leveraged banks, and the failure of Lehman Brothers. On September 29, 2008 alone the Dow lost 777.68 points after Congress first rejected the bank bailout.

The Federal Reserve and Treasury responded with rate cuts, bailouts, and quantitative easing. Even so, the S&P 500 did not close back above its 2007 peak until March 2013, about five and a half years later (Wikipedia).

2020: The COVID crash

The pandemic crash was the fastest bear market ever recorded. From its February 19, 2020 peak, the S&P 500 fell 34% in just 33 calendar days, entering bear-market territory (a 20% drop) in only 16 trading sessions, shattering the previous record set in 1929. Two of the largest one-day Dow drops in history came that March.

The rebound was just as extraordinary. Backed by near-zero rates, unlimited quantitative easing, and a $2.2 trillion stimulus package, the S&P 500 recovered to a new all-time high by August 18, 2020, about five months after the low, and finished the year up roughly 18%.

How deep do crashes go?

Depth varies enormously (see the chart below). The 1929 Dow fell about 89% and the 2000 Nasdaq about 78%, the two deepest. The 2008 S&P 500 fell 57%, while the 1987 and 2020 crashes each bottomed near a 34% loss.

The pattern is that concentrated bubbles (1929 speculation, 2000 tech) cut deepest, while shocks met with fast policy support (1987, 2020) tend to be shallower. For comparison, the average bear market since 1928 has fallen about 35%.

How deep do crashes go?

Peak-to-trough decline of the main index for each crash. 1929 = Dow; 2000 = Nasdaq; others = S&P 500. Values are approximate, derived from cited index levels.

How long until recovery?

Recovery time, not depth, is what tests investors (see the chart and table below). The 1929 crash took 25 years to regain its peak in nominal price terms, and the 2000 Nasdaq took 15 years. The 2008 S&P 500 needed about 5.5 years.

At the other extreme, 1987 recovered in roughly two years and the 2020 crash in about five months. Across all bear markets, Ned Davis Research data compiled by Hartford Funds puts the average recovery at about 2.5 years, though a few secular busts skew that far higher.

The biggest single days

Crashes are often remembered by their worst single sessions (see the chart and table below). Black Monday 1987 still stands alone at -22.6%, more than the second-worst day, March 16, 2020, at -12.9%.

The 1929 crash contributes two of the top four: Black Monday (-12.8%) and Black Tuesday (-11.7%). Point losses look bigger today only because the index is far higher: the Dow's 777.68-point drop on September 29, 2008 was just a 7.0% move.

Crashes, bear markets, and corrections

The terms are not interchangeable. A correction is a decline of 10% or more, a bear market is a fall of 20% or more, and a crash is a sudden, severe drop, often the sharp opening phase of a bear market. All five events here were both crashes and bear markets.

The averages matter for context (see the table below). Since 1928 there have been 27 bear markets averaging a 35% loss, against 28 bull markets that gained 112% on average and lasted 2.7 years. Over time the up years have vastly outweighed the down ones.

Volatility: the fear gauge

The VIX, Wall Street's fear gauge, spikes during crashes as options prices reflect panic. Its two extremes both came from the events on this list: an all-time intraday high of 89.53 on October 24, 2008, and the highest-ever close of 82.69 on March 16, 2020 (see the table below).

Remarkably, every one of the 69 highest VIX closes on record occurred during just two windows, the 2008 financial crisis and the 2020 pandemic, per Macroption's CBOE data. A VIX above 40 is rare and historically has clustered near market bottoms.

How often do crashes happen?

Bear markets are more common than most investors assume, but they are not evenly spaced (see the table below). Since 1928 there have been 27, roughly one every 3.5 years, but the pace has slowed: 12 struck between 1928 and 1945 (one every 1.5 years) versus 15 since 1945 (one every 5.1 years).

The reassuring flip side is that bear markets have made up only about 21 of the last 95 years, meaning stocks have been rising roughly 78% of the time. Downturns are the exception, not the norm.

What crashes have in common

Different triggers, similar anatomy. Most crashes follow a run-up in valuations and leverage (margin debt in 1929, portfolio insurance in 1987, tech valuations in 2000, mortgage leverage in 2008) that leaves the market fragile when confidence breaks.

The other constant is the policy response. The 1929 crash was met with a passive Fed and turned into a depression; 1987, 2008, and 2020 were met with aggressive central-bank and fiscal action, which is a big reason their recoveries were far faster. Faster policy pivots have consistently meant faster rebounds.

What it means for you

The single clearest lesson from a century of crashes is that the market has recovered from every one, so the biggest risk for a long-term investor is selling at the bottom and missing the rebound. About 42% of the market's strongest days have occurred during bear markets, and 36% of its best days in the first two months of a new bull market, per Hartford Funds.

That argues for staying invested through volatility, holding a diversified mix so no single crash sinks your plan, and keeping an emergency fund in cash so you are never forced to sell stocks at a low. Time in the market, across the full cycle of crashes and recoveries, has beaten trying to time the crashes themselves.

Frequently asked questions

What was the worst stock market crash in history?

By depth, the 1929 crash was the worst: the Dow fell about 89% from its September 1929 peak to its July 1932 low, and it took 25 years to regain that peak. The 2008 crisis (S&P 500 -57%) and the 2000 dot-com bust (Nasdaq -78%) were the next most severe.

How long does it take the stock market to recover after a crash?

It varies enormously. The 2020 COVID crash recovered in about five months, and 1987 in roughly two years, but 2008 took about 5.5 years, the Nasdaq after 2000 took 15 years, and the 1929 crash took 25 years. Across all bear markets the average recovery is about 2.5 years.

What was the biggest single-day stock market drop?

Black Monday, October 19, 1987, when the Dow fell 22.6% in one day, the largest one-day percentage drop in modern history. The next largest was March 16, 2020 (-12.9%), followed by Black Monday and Black Tuesday of the 1929 crash (-12.8% and -11.7%).

How often do stock market crashes happen?

There have been 27 bear markets (drops of 20% or more) since 1928, roughly one every 3.5 years. They are getting rarer: about one every 1.5 years before 1945 versus one every 5.1 years since. Bear markets have made up only about 21 of the last 95 years.

What caused the 2008 stock market crash?

The 2008 crash was driven by subprime mortgage losses, heavily leveraged banks, and a housing bubble that burst. The failure of Lehman Brothers in September 2008 triggered a credit freeze. The S&P 500 fell 57% from its October 2007 peak to a low of 666 in March 2009.

Should I sell my stocks during a market crash?

History suggests selling at the bottom is the biggest danger, because the market has recovered from every crash and the best days often cluster right after the worst ones. About 42% of the market's strongest days have occurred during bear markets. Staying diversified and invested has historically beaten trying to time crashes.
