I used to be a university intern at an area funding agency once I first discovered what a “inventory market crash” was. It was 2001 and the market was already on the decline. After the tragic occasions of 9/11, the inventory market continued to lose worth.
Right here’s how the S&P 500 regarded in 2001 (chart courtesy of Koyfin.com):

The chart above could present what the inventory market crash “regarded” like however I guarantee you it doesn’t seize what it felt like.
The look of defeat on the monetary advisors I used to be working with couldn’t go unnoticed. For those who lived it the crash didn’t cease in 2001. It continued effectively into 2002 erasing thousands and thousands of wealth in our nation.
I assumed that was the inventory market crash I might ever witness in my life. That was till 2008…
New traders typically consider inventory market crashes as uncommon occasions when in reality, the alternative is true. The market experiences a crash each few years. Whereas the COVID Crash of 2020 might need been a nightmare in its personal proper, it’s removed from the worst crash ever.
That one was so short-lived that you just in all probability don’t even keep in mind it occurred. However since I skilled 2 inventory market crashes pretty shut to one another and recognizing it has been over 13+ years since anybody has skilled a extremely extreme down market, I assumed it might be a good suggestion to warn new traders.
Particularly for those who began investing with on-line apps or brokers which have solely seen inexperienced once they test their accounts.
To place the inventory market crash issue into perspective, I’ve put collectively this checklist of the highest 10 worst inventory market crashes in historical past.
As you’ll see, inventory market crashes are available all styles and sizes, they usually’re even frequent all through historical past. This checklist goes on the best way again to 1907, which works to point out you the way lengthy crashes have been going down.
What’s a Inventory Market Crash?
A inventory market crash is a noticeably fast decline in share costs. Shares usually fluctuate, even inside the identical day.
There may even be identifiable patterns, just like the market rising on a number of share factors one week, then falling a number of the following. All of it balances out, and both the market continues to rise, or stays in a slender buying and selling sample.
We will consider a crash as being a disturbance within the regular sample.
Fairly than repeating the cycle of short-term advances and declines, the market goes right into a deep dive.
There’s no particular definition of what a inventory market crash is, they usually’re typically labeled effectively after the actual fact. However a inventory market crash could be seen as an unusually giant decline available in the market, usually taking place inside a short while body.
The Totally different Causes of Inventory Market Crashes
Market crashes can come about due to prolonged positive factors, which may final over a few years. These are generally known as bubbles, that may come crashing down when valuations get too excessive. A very good instance of this was the Dot-com Bust in 2000 (which solely made #8 on this checklist).
Losses in that crash had been concentrated in expertise shares that reached ranges that don’t have anything to do with their monetary fundamentals. What occurred afterward was completely predictable, though it didn’t appear apparent on the time
Different occasions, market crashes are brought on by main occasions. Examples embrace the World Warfare II Crash (#7 under) and the Crash of 2020 (#10). One was brought on by a world struggle, and the opposite by a worldwide pandemic.
Like market bubbles, market crashes final till they peter out. That’s normally caused by a mix of inventory costs falling to extra affordable ranges, and a few mixture of optimistic developments that reverse the negativity that precipitated or contributed to the crash.
The upshot is that every crash units up the following growth. For that motive, we should always consider crashes as a possibility to purchase shares at deep reductions.
What’s the Distinction Between a Inventory Market Crash and a Bear Market?

It may be troublesome to ascertain the dividing line between a inventory market crash and a bear market. That is largely as a result of the top outcome is identical – most traders lose cash, and normally lots of it.
However the principle issue separating the 2 is period. Crashes are typically brief and sharp. For instance, the market could lose 30% in simply two or three months. Or within the case of the Crash of 1987 (#9), it could final only some weeks.
There have been crashes that lasted only some days. These are what are sometimes called flash crashes.
Bear markets, then again, are likely to last more. Typically, they’ll go no less than one yr, however can typically run for 2 or three.
Some bear markets, just like the Crash of 1929, lasted for a number of years, and embrace a collection of crashes.
This grey zone between inventory market crashes and bear markets additionally explains why there are totally different lists on what make-up the largest crashes in historical past.
Prime 10 WORST Inventory Market Crashes in Historical past
Our checklist of the highest 10 worst inventory market crashes in historical past takes in each identifiable crash since 1900. Generally, I’ve used the Dow Jones Industrial Common to find out the proportion decline and period of every crash.
That’s as a result of it was the first measure of the inventory market, no less than till the Seventies, when the S&P 500 and the NASDAQ began changing into extra commonplace measures.
Listed below are the highest 10 inventory market crashes in historical past:
1. September 3, 1929 to July 8, 1932
Proportion Decline: 89.2%
Period: 34 months
For sure, this crash is the worst in inventory market historical past. It was the primary of a collection of crashes that occurred in the course of the Thirties and early Nineteen Forties, in the course of the time generally known as the Nice Melancholy.
What made the Crash of 1929 so extreme was that it adopted a decade of double-digit annual returns within the inventory market. From there, the crash took maintain instantly. Between September 3, and November 13, the market misplaced 45% of its worth in simply over two months. That doubtless qualifies as the one largest flash crash in historical past. Sadly, that moved the market solely midway to its final backside.
The worst a part of the crash occurred throughout three single buying and selling days. October 24, which turned referred to as Black Thursday, noticed the market lose 11% of its worth on heavy buying and selling.
That was adopted by Black Monday, on October 28 – simply two buying and selling days later. On that day the market gave up one other 12.8%.
The punch-drunk market was hit arduous on the very subsequent day, Black Tuesday, with the market giving up 11.7%. Whole market losses for simply two days hit 25%. That shaped the largest two-day loss in inventory market historical past.
Efforts by rich traders to inject money into the market and prop up costs failed. Many shares buying and selling on the New York Inventory Alternate had no consumers in any respect, making a worst-case situation. A whole bunch of corporations filed for chapter after the crash.
The Crash of 1929 – By the Numbers
From begin to end, the Dow Jones Industrial Common skilled the largest bear market in historical past. After peaking at 381.17 on September 3, 1929, the Dow Jones Industrial common hit backside at 41.22 on July 8, 1932. That resulted in an general lack of 89.2%.
The decline was so steep that it might take till November 23, 1954, earlier than the index would lastly get well to its precrash excessive. Put one other means, in case you had been invested available in the market in September 1929, it might’ve taken simply over 25 years on your portfolio to totally get well.
2. March 6, 1937 to March 31, 1938
Proportion Decline: 54.5%
Period: 12.8 months
Although the Crash of 1929 hit all-time low in 1932, it hardly gave option to a brand new bull market. As mentioned within the earlier crash, the Thirties is characterised by a collection of crashes. The one which occurred between March 6, 1937, and March 31, 1938, was a type of crashes. It was no strange crash both, taking the market down effectively over 50% in just a bit over one yr.
Although the worst of the Nice Melancholy appeared to be over and the economic system and the monetary markets had made important progress for the reason that backside in 1932, there was little stability. 1937 noticed the start of the Recession of 1937-1938, triggering a pointy decline within the inventory market.
Throughout that point, unemployment elevated from 14.3% in Might 1937, to 19% in June 1938. In the meantime, manufacturing output fell by 37%. Along with the recession, doubts had arisen concerning the skill of Franklin D. Roosevelt’s New Deal to carry the economic system out of the Melancholy.
The inventory market lastly started to get well in April 1938, only a few months earlier than the recession restoration began. Nonetheless, the Dow Jones Industrial Common wouldn’t get well the bottom it misplaced till 1945, and the top of World Warfare II.
3. October 9, 2007 to March 9, 2009
Proportion Decline: 54.1%
Period: 17 months
This crash takes the prize as the largest for the reason that Nice Melancholy. It almost matched the decline of the 1937 – 1938 crash however did it over a considerably longer time-frame. The Dow Jones industrial common fell from a pre-crash peak of 14,164.53 to a low of 6,469.95.
Whereas the decline within the Dow Jones industrial common reached 54.1%, the declines within the NASDAQ and the S&P 500 had been barely bigger, at 54.9% and 56.8%, respectively.
Although the 2007 – 2009 crash began with the meltdown within the mortgage trade, notably with subprime mortgages, it quickly unfold all through the economic system. Inventory markets world wide additionally declined with US markets, inflicting a worldwide monetary contagion.
That included an explosion in residential residence foreclosures and a pointy enhance in unemployment. The inventory market decline was accompanied by what was thought of to be the worst financial downturn within the US for the reason that Nice Melancholy.
Each the inventory market and the economic system started turning round when the federal government took emergency measures, and the Federal Reserve launched Quantitative Easing, slicing rates of interest to ranges by no means seen in historical past, and flooding the economic system with recent money.
As dangerous because the 2007 – 2009 crash was, it was additionally the start of the 2009 – 2020 bull market, which has been probably the most explosive in historical past.
4. January 11, 1973 to October 3, 1974
Proportion Decline: 48.2%
Period: 20.7 months
This crash had been the worst in US historical past for the reason that Nice Melancholy, no less than up till it was overshadowed by the 2007 – 2009 crash.
The crash may much more sophisticated than most, in that it had a number of causes.
First, was the so-called Nixon Shock of 1971. Then-President Richard Nixon enacted a collection of financial and monetary reforms in 1971. Most outstanding of those was to disconnect the US greenback from gold.
Till that point, the greenback had all the time been convertible into gold at a set worth. The Nixon Administration severed that convertibility, inflicting the greenback to develop into a floating forex. This diminished the steadiness of the greenback, and ignited inflation.
The market crash was made worse by a mix of financial recession and the 1973 oil disaster, which precipitated the worth of oil to just about quadruple in October of that yr. The sudden and dramatic enhance within the worth of oil accelerated the overall inflation that was gripping your entire economic system.
The greenback devaluation, the explosion within the worth of oil, and the deep recession mixed to create one of many largest inventory market crashes in historical past.
5. September 7, 1932 to February 27, 1933
Proportion Decline: 40.6%
Period: 5.75 months
The Crash of 1929 ended on July 8, 1932. However simply two months later, the inventory market was again in crash place. Perhaps the restoration from the earlier crash was nothing greater than a bear market bounce. However this one is taken into account to be a separate crash as a result of, regardless of the severity of the decline, the market by no means reached the depths of the earlier crash.
6. January, 1907 to November, 1907
Proportion Decline: 40.4%
Period: 11 months
Generally known as the Panic of 1907, this crash isn’t acquainted to most traders right now. But it surely might need been the worst crash skilled up till that time.
The panic began with financial institution shares. Since there was additionally an financial recession, there have been financial institution runs as depositors went to drag their cash out of struggling banks. Efforts to cease the market decline failed, inflicting the financial institution runs to extend.
The crash resulted within the failure of enormous banks, inflicting a contagion to unfold to banks throughout the nation. The selloff on Wall Avenue ate up itself, culminating in November 1907.
7. October 1939 to April 28, 1942
Proportion Decline: 38%
Period: 32 months
We will loosely check with this because the World Warfare II Crash, because it started shortly after Germany invaded Poland in September, 1939. After hitting a excessive of 152 in October 1939, the Dow Jones Industrial Common fell all the best way right down to 95 by April 1942.
This was hardly shocking, given the magnitude of World Warfare II, and the uncertainty of its consequence within the early days of the struggle. Not surprisingly, it lasted nearly so long as the Crash of 1929.
8. March 10, 2000 to October 4, 2002
Proportion Decline: 36.8%
Period: 26.8 months
Generally known as the Dot-com Bust, this crash ranks #8, however solely primarily based on the efficiency of the Dow Jones Industrial Common. However the actual injury was within the NASDAQ, which skilled a decline of about 80%. Primarily based on the NASDAQ efficiency, the Dot-com Bust qualifies because the second largest crash/bear market in US historical past.
However the sharp separation between the efficiency of the Dow Jones and the NASDAQ highlighted two very distinct markets.
As crashes go, the efficiency of the Dow wasn’t notably spectacular. However the scenario was completely totally different with the NASDAQ. A lot of this needed to do with the distinctive nature of the shares buying and selling on the NASDAQ at the moment.
The Nineties noticed a fivefold enhance in expertise inventory costs. Actually, the expansion section was confined to simply 5 years, 1995 to 2000. Throughout that point, expertise shares had been awash with enterprise capital. Practically any firm that introduced itself as being related in any means with expertise noticed huge positive factors in share worth. Most of the shares had no income in any respect. It was the very definition of a inventory market bubble.
The market started to crash as funding capital dried up. And as is usually the case, promoting begets extra promoting, and crash turned self-sustaining.
9. August 25, 1987 to October 19, 1987
Proportion Decline: 36.1%
Period: Lower than 2 months
In some methods, that is probably the most uncommon inventory market crash in historical past. From August 1982 to August 1987, the Dow Jones Industrial Common almost quadrupled. But it surely all got here to a screeching halt throughout that very same month. The market started to say no step by step – then instantly on October 19.
In a single day – dubbed “Black Monday” – the Dow misplaced 22.6%, making it the biggest share one-day loss in historical past.
After reaching a report excessive of 2722 on August 25, 1987, the market bottomed at 1738 on October 19, for a complete lack of 36.1%.
The explanations for the crash are nonetheless being debated, however what made it actually uncommon was the fast restoration.
The inventory market started recovering just about the following day. It continued rising after that, although the market wouldn’t totally get well from the crash till the early Nineties.
10. February 19, 2020 to March 23, 2020
Proportion Decline: 34%
Period: 33 days
Primarily based on the Customary & Poor’s 500 index, the market fell by 34% in simply 33 days. Pound for pound, this might need been probably the most critical crash in historical past. But it surely was brief in period, and the market not solely totally recovered inside months, however went on to set a succession of report highs.
The background driver was the COVID-19 pandemic that was shortly sweeping world wide. Unable to cease the contagion, governments world wide actually shut down their economies. The outcome was not solely an enormous financial shock, but additionally a sudden lack of confidence within the monetary markets.
However fast motion by the Federal Reserve to institute extra financial aid introduced the crash to an finish in amazingly little time. After, the market resumed powering ahead, as if the crash by no means occurred.
