Black Monday 1987: Causes, Crash and Recovery Timeline
On October 19, 1987 the S&P 500 fell 20.47% in a day. What caused it, and when the market recovered: 21 months by price, about 19 with dividends, over 4 years after inflation.
The Nasdaq fell 78% after March 2000 and took 15 years to regain its high. The S&P 500 fell 49%, was back by 2007, and has stayed above its 2000 record since 2013.

The dot-com bubble burst in March 2000. The Nasdaq Composite, an index weighted heavily toward technology companies, fell 78% and took 15 years to close back above its record. The broader S&P 500 fell 49% and first got back in 2007, but the 2007-2009 financial crisis took that recovery away. It has closed above its 2000 record at every trading-day close since March 5, 2013.
How long recovery took depends on which index you measure, whether you count dividends and inflation, and whether you mean the first day back or a lasting recovery. Counting reinvested dividends, an S&P 500 fund such as SPY has closed above its March 2000 value since December 2011.

The dot-com bubble burst in March 2000, though not on the same day for every index. For the Nasdaq Composite, the top was a record close of 5,048.62 on Friday, March 10, 2000. A month later it was in a bear market, the usual name for a fall of 20% or more from a high. On Wednesday, April 12, 2000 it closed at 3,769.63, 25.3% below the record. In the week of April 10 to 14 alone it lost a quarter of its value, including a 9.67% fall on Friday, April 14.
The broader market took longer to crack. The S&P 500 set its record of 1,527.46 on March 24, 2000, two weeks after the Nasdaq. As late as September 1, 2000 it closed within half a percent of that record. Its first close 20% below the record came on March 12, 2001, 11 months after the Nasdaq's. The Dow Jones Industrial Average, an average of 30 large US companies with far less technology in it, had peaked earlier still, on January 14, 2000.
All three hit their lowest close of the dot-com bust on the same day: Wednesday, October 9, 2002, about two and a half years after the bubble burst. The 2007-2009 financial crisis later took the S&P 500 and the Dow lower still, in March 2009.

December 5, 1996
Fed chair Alan Greenspan asked in a speech how anyone could know when "irrational exuberance" had pushed prices too high. That day's Nasdaq close: 1,300.12.
March 10, 2000
Record close for the Nasdaq Composite: 5,048.62. The S&P 500 set its own record two weeks later, on March 24, at 1,527.46.
April 10 to 14, 2000
In one week the Nasdaq lost 25.3%, including 9.67% on Friday, April 14.
March to November 2001
The US economy was in recession. After the September 11 attacks, stock markets closed for four trading days, and the Dow fell 7.1% when they reopened on September 17.
October 9, 2002
Both indexes hit bottom: the Nasdaq 78% below its record, the S&P 500 49% below its own.
May 30, 2007
The S&P 500 closed above its 2000 record for the first time. From November 2007, as the financial crisis began, it stayed below until 2013.
March 5, 2013
From this day the S&P 500 closed above its 2000 record at every close, through October 23, 2026.
April 23, 2015
First close above the March 2000 record, at 5,056.06. It has closed above it since November 7, 2016.
How much the stock market dropped in the dot-com crash came down to which part of it you held: from each index's record close to its low on October 9, 2002, the Nasdaq Composite fell 78%, the S&P 500 fell 49% and the Dow fell 38%. The often-quoted 78% is the Nasdaq. If you had owned an index fund tracking the S&P 500, you would have lost about half from the March 2000 peak to the 2002 low, not four-fifths.
In 2000 alone, from the last close of 1999 to the last close of 2000, the S&P 500 fell about 10% by price and the Nasdaq 39%. Two more losing years followed: about 13% and 23% for the S&P 500 in 2001 and 2002, and about 21% and 32% for the Nasdaq.

"$10,000 became" follows $10,000 from each index's record close to its low on October 9, 2002, price only, without dividends. Historical data shown; past performance does not indicate future results.
| Index | Record close | Low close (Oct 9, 2002) | Fall | $10,000 became |
|---|---|---|---|---|
| Nasdaq Composite | 5,048.62 (Mar 10, 2000) | 1,114.11 | -78% | $2,207 |
| S&P 500 | 1,527.46 (Mar 24, 2000) | 776.76 | -49% | $5,085 |
| Dow Jones Industrial Average | 11,722.98 (Jan 14, 2000) | 7,286.27 | -38% | $6,215 |
By price, recovering from the dot-com bubble took 15 years for the Nasdaq and 7 to 13 years for the S&P 500. That is 7 years to the S&P 500's first close back and 13 until it stayed back. On April 23, 2015, the Nasdaq Composite closed at 5,056.06, its first close above the March 10, 2000 record. The wait was shorter for the S&P 500. It first closed above its March 24, 2000 record on May 30, 2007, slipped below it often that summer, and from November 1, 2007, as the financial crisis began, stayed below it until 2013. In March 2009 it fell to 676.53, 56% below its 2000 record and lower than its 2002 low. From March 5, 2013, it did not close below that 2000 record again, through October 23, 2026. (Its 2007 record of 1,565.15 is a different line; it passed that on March 28, 2013.)
Dividends, the cash many companies pay their shareholders, shorten the wait. SPY, a fund that tracks the S&P 500, shows the difference. With dividends reinvested, it first closed above its March 2000 value on October 26, 2006, by our calculation from its dividend-adjusted prices. It hovered around that level for a few weeks, fell below again in January 2008, and has closed above it at every close since December 21, 2011. If you hold a different S&P 500 index fund, your figures can differ slightly because of fees, tracking differences, taxes and dividend timing.
Inflation lengthens the wait. Measured by price in March 2000 dollars, both indexes slipped back below the line in later sell-offs, most recently in the March 2020 crash, which is why those rows reach 2020. With dividends counted too, the S&P 500 stayed above from 2013. We do not show a Nasdaq row with dividends because we could not find a free long-run daily series for it.
For comparison, measured the same way, the S&P 500 took 23 months by price to pass its August 1987 record (21 months after Black Monday itself). The Dow took about 25 years to pass its 1929 record, and about 9 years and 8 months after its January 1906 record in the Panic of 1907.

"First close back" is the first close above the 2000 record. "Stayed above from" is the first trading day after the last close below it, through October 23, 2026; a later fall below the record would change it. Times are counted from each index's own record, in whole months. Inflation rows use the monthly consumer price index, so they are accurate to the month. SPY's row uses its own dividend-adjusted closes, which include its small fund fees; the other dividend row uses the index rebuilt with dividends, reinvested with no costs or taxes (Robert Shiller's monthly data agrees on May 2013; SPY's own prices give September 2013 for the row's second date, because of its fees). Historical data shown; past performance does not indicate future results.
| Measure | First close back | Time to first close back | Stayed above from | Time to stay above |
|---|---|---|---|---|
| S&P 500 index fund (SPY), dividends reinvested | Oct 26, 2006 | 6 years 7 months | Dec 21, 2011 | 11 years 8 months |
| S&P 500, price | May 30, 2007 | 7 years 2 months | Mar 5, 2013 | 12 years 11 months |
| S&P 500, dividends reinvested, after inflation | May 2013 | 13 years 1 month | Jul 2013 | 13 years 3 months |
| S&P 500, price, after inflation | Feb 2015 | 14 years 10 months | Mar 2020 | 20 years |
| Dow, price | Oct 3, 2006 | 6 years 8 months | Nov 30, 2011 | 11 years 10 months |
| Nasdaq Composite, price | Apr 23, 2015 | 15 years 1 month | Nov 7, 2016 | 16 years 7 months |
| Nasdaq Composite, price, after inflation | Jan 2018 | 17 years 10 months | Apr 2020 | 20 years |
If you had kept investing every month through the dot-com crash, your account would have climbed back above the money you paid in. It got there years before a single sum invested at the peak recovered. Take $100 put into an S&P 500 index fund on the first trading day of every month from March 2000, with dividends reinvested. At its lowest point in the dot-com bust, on July 23, 2002, the account held $1,899 against $2,900 paid in: 35% less than had gone in, a shortfall against deposits rather than the account's own fall from a high. By December 12, 2003, three years and nine months after the first $100, it was back above everything paid in. A single sum invested at the March 2000 peak needed until October 2006. The two investors put in different amounts at different times, so the comparison shows how the timing of deposits changes the wait.
That happened because the later deposits bought more of the fund after prices had fallen, an approach called dollar-cost averaging. Being above the money paid in is a low bar: it counts dollars, not what those dollars could buy, and not what the money might have earned elsewhere. The same account fell below what had been paid in again during the 2007-2009 crisis. On our reconstruction of the index with dividends, it stayed above from mid-2010. The example assumes no fees or taxes and a fixed $100 a month; Sources and Method gives the details. You can try other amounts in our DCA vs lump sum calculator. It worked here because the S&P 500 recovered; a different market or time could look different. Past performance does not guarantee future results.
Published answers to how long the dot-com recovery took mostly run from about 7 to 17 years, and counting inflation and a lasting recovery stretches it to 20. Four choices explain the spread:
One date often gets mixed up. Some pages say the Nasdaq recovered in May 2013, but its closes that month ran from 3,299 to 3,502, about a third below the 2000 record. May 2013 is when the S&P 500, with dividends and after inflation, first got back. It is not a Nasdaq date.
Each figure is counted from the index's own 2000 record to the date shown. Historical data shown; past performance does not indicate future results.
| If a source says | It usually means | Date |
|---|---|---|
| About 7 years | S&P 500 by price, first close back | May 30, 2007 |
| About 13 years | S&P 500 by price, stayed above | Mar 5, 2013 |
| About 15 years | Nasdaq Composite by price, first close back | Apr 23, 2015 |
| About 17 years | S&P 500 Information Technology sector by price | Jul 19, 2017 |
| About 18 years | Nasdaq Composite after inflation, first close back | Jan 2018 |
| About 20 years | Either index after inflation, stayed above | Mar and Apr 2020 |
The dot-com bubble's rise lasted several years and its bust about two and a half. There is no agreed date for when the rise began. One marker of how far it had already run is a speech on December 5, 1996. In it, Federal Reserve chair Alan Greenspan asked how anyone could know "when irrational exuberance has unduly escalated asset values." From that day's close of 1,300.12, the Nasdaq rose almost fourfold to its record over the next 3 years and 3 months. In the same years the S&P 500 roughly doubled to its own record. The bust then ran about two and a half years, from the Nasdaq's record on March 10, 2000 to its low on October 9, 2002.
Several pressures arrived together, and prices had run far ahead of profits. Jay Ritter, a University of Florida professor who tracks IPOs, counted 856 IPOs in 1999 and 2000 in his sample of operating companies priced at $5 a share or more. Of those, 78% had lost money in the year before going public, against 32% from 1990 to 1998. The internet did change the world; that did not mean every internet company was worth the price investors paid for it. Between June 1999 and May 2000, the Federal Reserve raised its target for the federal funds rate six times, from 4.75% to 6.5%. That is the rate banks charge each other for overnight loans, and raising it pushes up borrowing costs across the economy. One sharp sell-off came on Monday, April 3, 2000. After talks to settle the government's antitrust case against Microsoft (a case about unfair competition) broke down over the weekend, the Nasdaq fell 7.6% that day. A judge ruled against Microsoft after trading had closed.
The decline did not stop with the internet companies. The Fed began cutting rates on January 3, 2001. A US recession followed, from March to November 2001, by the dating of the National Bureau of Economic Research. Stock markets stayed closed for four trading days after the September 11, 2001 attacks, and the Dow fell 7.1% when they reopened on September 17. Accounting scandals then hit confidence again before the October 2002 low. Enron filed for bankruptcy on December 2, 2001, and WorldCom on July 21, 2002.
A portfolio's mix changes even if you never trade. In our replay, $10,000 starts on December 4, 1996 as $6,000 in the S&P 500, $3,000 in the Nasdaq and $1,000 in cash. Left untouched, the tech-heavy Nasdaq part grew from 30% to 48.8% of the money by March 10, 2000, because it rose fastest. The whole mix peaked at $24,780, up 147.8%, on March 24, 2000. At the October 9, 2002 low it was worth $9,832, 1.7% below where it began. These are game results based on index prices only, before dividends, fees or taxes. Past performance does not guarantee future results.
Resetting a mix to its starting percentages is called rebalancing. The portfolio allocation lesson explains how it works. It cuts both ways: trimming technology in 1998 meant owning less of the climb as well as less of the fall. The dot-com replay lets you watch the drift happen, decision by decision.
Quick answers on the dot-com crash and the recovery, from the same daily closing prices as the rest of this page.
Measured by price, the S&P 500 took 7 years to first close back above its March 2000 record (May 30, 2007) and 13 years to stay above it (from March 5, 2013). The Nasdaq Composite took 15 years (April 23, 2015).
By closing price, the Nasdaq Composite first closed above its March 10, 2000 record of 5,048.62 on April 23, 2015. It dipped below that level again and has closed above it since November 7, 2016. It did not recover in May 2013, as some pages say.
By price, the S&P 500 first closed above its March 24, 2000 record of 1,527.46 on May 30, 2007. It moved above and below that level through 2007, stayed below from November 1, 2007, and has stayed above it since March 5, 2013. With dividends reinvested, an S&P 500 fund stayed above its March 2000 value from December 2011.
On October 9, 2002, the Nasdaq Composite closed at 1,114.11, 77.9% below its March 10, 2000 record and its lowest close since August 1, 1996. Both the S&P 500 and the Dow hit their dot-com lows the same day; both fell lower still in March 2009, during the financial crisis.
Pets.com sold shares to the public in February 2000 and closed its online store on November 10, 2000. eToys told about 700 of its roughly 1,000 employees in January 2001 that their jobs would end, and filed for bankruptcy on March 7, 2001. Webvan, an online grocer, filed for bankruptcy on July 13, 2001. The dates come from the companies' own filings with the SEC.
Often far longer than the indexes, and many never did. Amazon fell more than 90% from its December 1999 record and first closed above it on October 23, 2009. Microsoft did not close above its December 27, 1999 record until October 21, 2016, almost 17 years later; with dividends reinvested, it got back on July 16, 2014. Cisco, which made much of the networking equipment the internet ran on, closed at a record $80.06 on March 27, 2000, fell almost 90% by October 2002, and did not close above that price again until December 10, 2025. Counting reinvested dividends, on Yahoo Finance and StatMuse dividend-adjusted prices, it first passed its March 2000 value on August 24, 2021. Indexes recover partly because their members change: companies that fail or shrink drop out and growing ones join. Past performance does not guarantee future results.
Nobody can know that in advance, and this page does not try to say. Our post Are We in Another AI Bubble? sets out the arguments on both sides. What the dot-com years can show is how long recovery took for each kind of holding, which is what this page measures.
Method. "Recovered" means a closing price above the 2000 record close. It does not mean investors felt whole, kept their purchasing power or avoided taxes and fees. "Stayed above from" is the first trading day after the last close below the record, through October 23, 2026. SPY figures follow $1 invested at SPY's dividend-adjusted close on March 24, 2000, the S&P 500's record day; that adjusted close treats each dividend as reinvested on its ex-dividend date and already includes the fund's fees. The monthly example is a separate calculation (SPY to 2007, then the rebuilt index): it buys fractional fund units at each month's first closing price, values the account at every daily close and reinvests dividends. Durations are counted from each index's own record. Figures are price only unless they say dividends. Data checked October 26, 2026: daily closes through October 23, 2026; consumer prices through September 2026. This page is historical education, not investment advice.

Every post in this series measures crashes the same way; our market-history method explains how.
The bubble burst in March 2000; the fall ended on October 9, 2002
The Nasdaq fell 78% and the S&P 500 49%.
By price, the Nasdaq took 15 years to get back; the S&P 500 took 7 to 13
Seven to its first close back in 2007, thirteen to stay back from 2013.
Investing every month got an account back above its deposits sooner
$100 a month from March 2000 was back above what had been paid in by December 2003, a lower bar than a full recovery. Past performance does not guarantee future results.
"May 2013" is not a Nasdaq recovery date
It is when the S&P 500, with dividends and after inflation, first got back. The Nasdaq closed back above its record on April 23, 2015.

On October 19, 1987 the S&P 500 fell 20.47% in a day. What caused it, and when the market recovered: 21 months by price, about 19 with dividends, over 4 years after inflation.
The Dow fell 89% after 1929 and took 25 years to regain its high by price. With dividends reinvested and deflation counted, the market was briefly back by 1936 and for good by 1949.
The Dow fell 48.5% from its January 1906 high to its November 1907 low, mostly before the October bank runs. Recovery came in 1908 counting dividends, and in 1915 by Dow price.
