Throughout history, financial markets have seen their fair share of turmoil. From wars to economic crashes, significant historical events have left a lasting impact on market performance. While each crisis comes with its own set of challenges, there’s often a pattern in how markets behave during and after these events. Let’s take a closer look at how the stock market, especially the Dow Jones Industrial Average (DJIA) and S&P 500, reacted to some of these pivotal moments and what lessons investors can take away.
The Stock Market and Historical Crises: An Overview
When it comes to stock market performance, external factors such as wars, political changes, and economic crises can cause abrupt shifts. Investors tend to react emotionally to these events, which drives volatility in markets. One key indicator to watch is the Annual Percentage Change for SPY, which tracks the year-over-year changes in the average stock price for the SPDR S&P 500 ETF Trust (SPY). This metric helps investors gauge how broader market sentiment shifts over time and reveals the profound effects of historical events on stock prices.
Major Historical Crises and Immediate Market Impact
Historical events often shake the markets, sometimes causing immediate declines followed by eventual recovery. Let’s look at how the Dow Jones responded to some of the biggest crises since 1940:
| Event | DJIA Reaction Dates | Immediate % Gain/Loss | % Change Six Months Later |
|---|---|---|---|
| Fall of France (1940) | 5/9/40 - 6/22/40 | -17.1% | 7.0% |
| Pearl Harbor (1941) | 12/6/41 - 12/10/41 | -6.5% | -9.6% |
| Korean War (1950) | 6/23/50 - 7/13/50 | -12.0% | 19.2% |
| Cuban Missile Crisis (1962) | 10/19/62 - 10/27/62 | 1.1% | 24.2% |
| JFK Assassination (1963) | 11/21/63 - 11/22/63 | -2.9% | 15.1% |
| September 11th Attacks (2001) | 9/10/01 - 9/21/01 | -14.3% | 24.8% |
| Great Recession (2008) | 10/2/08 - 3/9/09 | -34.2% | 15.0% (partial recovery) |
The Immediate Shock
Historical events tend to induce panic selling in the markets. This was particularly evident during Black Monday in 1987 when the DJIA dropped a staggering 22.6% in just one day. This sharp decline occurred due to a mix of rising interest rates, fears of economic instability, and the growing use of computerized trading systems that accelerated the sell-off.
Similarly, in response to the Pearl Harbor attack in 1941, the DJIA dropped 6.5%, as uncertainty around the U.S.’s involvement in World War II rattled investors. This kind of panic selling is a common occurrence following unexpected events, as traders often prefer to protect their portfolios from the unknown.
The Road to Recovery
While the immediate reactions to crises are often extreme, the stock market tends to recover over time. For example, despite the 12.0% drop in the DJIA during the start of the Korean War, the market had rebounded by 19.2% just six months later. The pattern is consistent: following an initial sell-off, the market usually finds its footing again as the uncertainty starts to clear.
Take the Cuban Missile Crisis of 1962 as another example. During the tense period when the U.S. and the Soviet Union were on the brink of nuclear war, the DJIA actually gained 1.1%, and in the following six months, the market surged by over 24%. This shows that markets don’t always react to crises in predictable ways and that political resolution can lead to rapid recovery.

Notable Market Crashes: What Happened and Why?
The Great Depression (1929)
The stock market crash of 1929 is perhaps the most notorious in history. After a decade of reckless speculation and over-leveraged investing, the market finally collapsed in October 1929. By the end of that year, the market had lost about 25% of its value. Over the next few years, the economic downturn worsened, leading to the Great Depression.
Investors who had bought stocks on margin (using borrowed money) were hit the hardest, as they couldn’t repay their debts after the crash. It took the U.S. economy nearly a decade to recover, with unemployment peaking at 25% in 1933. This event serves as a warning against over-speculation and excessive borrowing.
Black Monday (1987)
Black Monday, on October 19, 1987, remains the largest single-day percentage decline in stock market history. Markets worldwide experienced a massive sell-off, and by the end of the day, the DJIA had plunged 22.6%. A key factor was the rise of computerized trading systems, which exacerbated the speed and scale of the sell-off. However, the market rebounded relatively quickly, with the DJIA recovering much of its losses within two years.
The Dot-com Bubble (2000)
During the late 1990s, the stock market saw unprecedented growth, particularly in technology stocks. Investors poured money into internet companies, many of which had little revenue or profit. By early 2000, the bubble burst, and the Nasdaq index, heavily composed of tech stocks, lost nearly 80% of its value by 2002. The dot-com crash wiped out trillions of dollars in market value, but it also set the stage for the next wave of successful tech companies, like Amazon and Google, which rose from the ashes.
The Great Recession (2008)
The financial crisis of 2008 was triggered by the collapse of the housing market. Financial institutions had invested heavily in mortgage-backed securities, and when housing prices fell, these securities lost much of their value. The crisis led to the failure of major financial firms like Lehman Brothers and required government intervention to stabilize the economy.
From its peak in 2007 to its bottom in 2009, the S&P 500 lost over 50% of its value. However, the market slowly recovered with the help of federal stimulus programs and low-interest rates, and by 2013, it had regained all its lost value.
The COVID-19 Pandemic (2020)
The COVID-19 pandemic triggered one of the most dramatic stock market crashes in history. Between February and March 2020, the DJIA fell over 37% as economies around the world shut down to contain the spread of the virus. However, thanks to unprecedented fiscal and monetary stimulus, including direct payments to individuals and businesses, the market rebounded quicker than many expected. By August 2020, the S&P 500 had already hit new all-time highs.
Lessons for Investors
-
Don’t Panic Sell
One of the most important lessons from these historical events is that panic selling can lead to missed opportunities for recovery. Even in the face of extreme market declines, long-term investors who stay the course tend to be rewarded. For example, after the September 11th attacks, the DJIA initially dropped 14.3%, but within six months, it had rebounded by nearly 25%.
-
Diversification is Key
Diversifying your investments across different asset classes can help protect against losses during market downturns. For instance, during the 2008 financial crisis, while stock markets were plunging, U.S. government bonds and gold provided a safe haven for investors.

Understand Market Cycles
Markets move in cycles, and downturns are a natural part of investing. While it can be difficult to watch your portfolio lose value during a crisis, it’s important to remember that markets historically recover. The dot-com bubble and 2008 financial crisis were both devastating in the short term, but they were followed by long periods of economic growth and market gains.
Conclusion: Market Resilience Through the Ages
The stock market’s reaction to crises is often swift and brutal, but history shows us that recovery is not only possible but probable. Whether it’s wars, economic recessions, or global pandemics, the market has consistently bounced back, often reaching new highs in the years that follow. For investors, the key takeaway is to remain calm, stay invested, and diversify your portfolio. While you can’t predict when the next crisis will occur, you can prepare by learning from the past and building a resilient investment strategy.
