Episode 9 of 12 The Greatest Crashes in Market History

COVID: The Fastest Bear Market in History

In February 2020, the S&P 500 was at an all-time high. Twenty-three trading days later, it had lost a third of its value. Nine sessions fell more than 4%. Circuit breakers tripped four times. March 16 was the worst day since Black Monday. And then, almost as suddenly as it began, it was over.

Worst day (Mar 16)

No crash in this series moved faster. Not Black Monday, which was worse in a single day but came after months of warning. Not Lehman, which took a year to unfold. Not the dot-com collapse, which dragged on for two and a half years. The COVID crash compressed everything — the denial, the panic, the capitulation, and the bottom — into 23 trading days.

On February 19, 2020, the S&P 500 closed at 3,386.15 — an all-time high. There were 15 confirmed COVID-19 cases in the United States. Italy had not yet locked down. The WHO had not declared a pandemic. The word “coronavirus” appeared mostly in the back pages. By March 23, the index had fallen to 2,237.40, erasing three years of gains. The speed was without precedent: the S&P went from all-time high to official bear market (down 20%) in just 16 trading days — shattering the previous record of 42 days set in 1929.

This episode alone produced more −4% days (nine) than any other in this series. And it produced them alongside some of the most spectacular rallies in history — March 13 surged +9.29%, March 24 soared +9.38%. The whiplash was relentless. During the 23 trading days from peak to trough, the average absolute daily move was 4.8%. In normal markets, it is less than 1%.

February 27: The First Shock

February 27, 2020 — down 4.42% to 2,978.76. The S&P 500 had already fallen 3.35% on Monday and 3.03% on Tuesday as Italy’s outbreak escalated. By Thursday, the index had given back its entire year-to-date gain in four sessions.

The catalyst was not new information about the virus itself — China’s case count was already plateauing. It was the realization that containment had failed outside China. Italy reported clusters in Lombardy. South Korea’s cases spiked. Iran acknowledged an outbreak. The market had been pricing in a China problem. Suddenly it was a global one.

This was the fastest correction (a 10% decline from a peak) in history — achieved in just six trading days. The median stock fell 3.24%. But the damage was still relatively orderly: the VIX rose but didn’t spike, credit markets held, and most investors treated it as a buying opportunity. The real panic had not yet begun.

March 9: Oil War Monday

−11.98%
S&P 500 return on March 16, 2020 — the worst day since Black Monday 1987

March 9, 2020 — down 7.60% to 2,746.56. Over the weekend, Saudi Arabia launched a price war against Russia, flooding oil markets after OPEC+ negotiations collapsed. Crude oil futures plunged 25% overnight — the largest one-day drop since the 1991 Gulf War. The double shock of pandemic fears and an oil price war sent markets into a spiral.

At 9:34 a.m. — four minutes after the opening bell — the S&P 500 hit the −7% Level 1 circuit breaker for the first time since it was implemented in 1997. Trading was halted for 15 minutes. When it resumed, the selling continued but at a more measured pace. Of 5,901 stocks tracked, 5,465 declined (92.6%), with a median return of −7.72%. Oil and energy stocks were devastated: the Energy Select Sector SPDR Fund fell 20% in a single session.

March 11–12: Pandemic and Travel Ban

March 11 — down 4.89% to 2,741.38. The World Health Organization officially declared COVID-19 a pandemic. The NBA suspended its season after Utah Jazz player Rudy Gobert tested positive. Tom Hanks announced he had the virus. In a single evening, the abstract threat became visceral reality for millions of Americans who hadn’t been paying close attention.

March 12 — down 9.51% to 2,480.64. President Trump addressed the nation from the Oval Office and announced a 30-day ban on travel from Europe — delivered in a way that initially sounded like it included cargo and trade. Futures, which had been modestly lower, plunged. The circuit breaker triggered again at the open. What followed was the fourth-worst day in S&P 500 history.

The breadth on March 12 was the most extreme of the entire crash: 5,550 of 5,908 stocks declined (93.9%), with a median return of −9.99%. The travel and hospitality industries were annihilated. Norwegian Cruise Line fell 35.80%. Royal Caribbean fell 31.77%. Carnival fell 31.17%. AerCap, which leases aircraft to airlines, fell 32.93%. The market was pricing in the possibility that entire industries might not survive.

Then, on March 13, the S&P surged 9.29% — its best day since October 2008 — after the White House declared a national emergency and announced expanded testing. The +9.29% rally the day after the −9.51% crash is a perfect illustration of the violence of this market: the third-best day and the fourth-worst day in history occurred on consecutive sessions.

“There are decades where nothing happens, and there are weeks where decades happen.” — Vladimir Lenin, repurposed by countless traders in March 2020

March 16: The Worst Day Since 1987

March 16, 2020 — down 11.98% to 2,386.13. This was the day the Federal Reserve was supposed to save. On Sunday evening, in an emergency action, the Fed cut interest rates by a full percentage point to near zero and announced $700 billion in quantitative easing — the most aggressive intervention since the 2008 crisis. Markets were supposed to rally. Instead, the S&P futures hit the −5% limit-down level within minutes of the announcement.

When the market opened on Monday morning, the circuit breaker triggered immediately. The message was devastating: if the Fed using its biggest weapon couldn’t stop the bleeding, what could? Investors didn’t sell because the news was bad. They sold because the rescue didn’t work.

The destruction was extraordinary. Of 5,907 stocks tracked, 5,388 declined (91.2%), with a median return of −10.82%. The median stock lost more than a tenth of its value in a single day. Performance Foods Group fell 42.57%. Gaming & Leisure Properties fell 41.09%. Celsius Holdings fell 39.89%. MGM Resorts fell 33.59%. Apache Corporation fell 32.24%. The selling was indiscriminate — quality, junk, growth, value, everything went down together.

March 16, 2020 was the worst single day for the S&P 500 since Black Monday on October 19, 1987 (−20.47%), and the third-worst day since 1946. It was also the fourth time the circuit breaker had been triggered in just six trading sessions — a frequency that the system’s designers never contemplated.

The Bottom and the Aftershocks

March 18 — down 5.18% to 2,398.10. The Senate was debating stimulus measures that would eventually become the CARES Act. Markets fell anyway, as initial jobless claims surged and state after state announced lockdowns.

March 20 — down 4.34% to 2,304.92. Triple-witching Friday — the simultaneous expiration of stock options, stock index futures, and stock index options contracts — added forced selling to an already-panicked market. New York State went on “PAUSE,” ordering all non-essential businesses closed. California had already issued a stay-at-home order the day before.

Then, on March 23, the S&P 500 touched 2,237.40 — the bottom. The Fed announced unlimited quantitative easing (removing the $700 billion cap set the previous week) and launched new facilities to buy corporate bonds, municipal bonds, and asset-backed securities. It was the most expansive monetary intervention in history. This time, the market listened. The S&P surged 9.38% on March 24 and never looked back.

Two aftershock crash days followed. April 1 — down 4.41% to 2,470.50, as the weekly jobless claims report showed 6.6 million Americans filing for unemployment in a single week — ten times the previous record. And June 11 — down 5.89% to 3,002.10, as second-wave fears surged after the Fed released its first economic projections since the pandemic began, forecasting unemployment at 9.3% by year-end and a 6.5% GDP contraction.

Stock Movers: March 16, 2020

On the worst day since Black Monday, the carnage was indiscriminate. Travel, hospitality, energy, retail — everything that required people to leave their homes was crushed. Among large-cap stocks:

The Recovery

The recovery was as historic as the crash. From the March 23 low of 2,237.40, the S&P 500 surged 30% in just three weeks. By August 18, 2020 — less than five months after the bottom — the index had reclaimed its February 19 all-time high. By year-end, it stood at 3,756.07, up 16.3% for the year. The fastest bear market in history was followed by the fastest recovery.

The catalysts were unprecedented: the Fed’s unlimited QE, the $2.2 trillion CARES Act (signed March 27), $1,200 stimulus checks, enhanced unemployment benefits, and the Paycheck Protection Program. The government essentially backstopped the entire economy. Investors who sold at the bottom — and many did — missed one of the greatest rallies in market history.

Timeline

The Bottom Line

The COVID crash was unique in the history of markets. It was caused not by financial excess or speculative mania but by a biological event that forced the deliberate shutdown of the global economy. For the first time, governments chose to cause a recession — and then spent trillions to offset the damage. The result was the fastest bear market and the fastest recovery in history.

Nine crash days in four months. Circuit breakers triggered four times in six sessions. A −11.98% single-day decline — the worst since 1987. And yet the S&P 500 finished 2020 up 16.3%. The lesson, reinforced once again: the worst days and the best days are inseparable. Six of the ten best days in S&P 500 history since 1946 occurred within two weeks of the worst days in March 2020. You cannot capture the rallies if you flee the crashes. The market does not ring a bell at the bottom.
