The stock market is subject to ups and downs. While it has the potential to generate massive riches, it also carries inherent risks, as history has proved with multiple epic crashes. These were moments that have made an indelible mark on the world’s economies, investors, and financial systems. But when did those stock market crashes happen in prominent examples, and why?
On this blog, we’ll dissect the key stock market crashes, why they happened, and how they relate to the bigger picture. Whether you are an investor, a finance student, or are just interested in the history of money, here are insights into these epic crashes and the lessons they impart.
What Is a Stock Market Crash?
Before we delve into individual crashes, it’s important to note the definition of “crash.” A stock market crash is a sudden, dramatic decline of stock prices across a significant cross-section of a stock market, resulting in a significant loss of paper wealth. This is usually in the short term, as a result of panic sales, overvaluation, or external macroeconomic factors.
Stock market crashes frequently lead to general economic downturns with declines in economic output, employment, and average consumption.
The Great Stock Market Crashes and Their Dates
The Wall Street Crash of 1929
When: October 1929
What Happened:
The stock market crash of 1929, which precipitated the Great Depression, was one of the most devastating financial crises in history. The collapse happened in stages over a few days, including “Black Thursday” (Oct. 24), “Black Monday” (Oct. 28), and “Black Tuesday” (Oct. 29).
Causes:
- There had been wild speculative bubbles that pushed stock prices up beyond any rational measure of value.
- Over-speculation was widespread, as many investors purchased stocks on margin (credit).
- An underlying fragility had built up after the economy turned south.
Impact:
- The crash was so devastating that it destroyed billions of dollars of wealth and contributed to widespread bank failures and soaring unemployment during the Great Depression.
- It also led to regulatory changes in the financial industry.
Crash of 1987 / Black Monday
When: October 19, 1987
What Else Was Going On In The World:
On March 13, at the same time around the world, stock markets collapsed, and the Dow Jones Industrial Average fell by 22.6% in the United States.
Causes:
- The sell-offs were sped up by computerized trading and “program trading.”
- Frothy valuations meant a brittle market.
- The negative attitude towards the conditions was compounded by panic.
Impact:
- The markets recovered more quickly than many had expected.
- This crash was a reassurance that algorithm-based trading can take things only so far.
- It eventually resulted in changes such as circuit breakers, which halt trading in periods of extreme volatility.
Dot-com Crash (2000–2002)
When: From March 2000 to October 2002
What Happened:
Investors lost their minds in the late 1990s and threw their money at any and every Internet company they could find. Hundreds of startups, which we called “dot-coms,” were valued enormously, even though their real profit was not nearly as high. Overvaluation and failures soon forced a huge market correction by March 2000.
Causes:
- Technology stocks are getting ahead of themselves.
- Public frenzy over the Internet and tech sectors.
- Many of the companies also did not have viable business models.
Impact:
- The NASDAQ Composite saw its value plunge by about 78%.
- Trillions of dollars of market value disappeared.
- It was another painful lesson on telling hype from investments that last.
The Financial Crisis of 2008
When: September 2008
What Happened:
Spurred by the bankruptcy of Lehman Brothers, this crisis ripped apart world financial markets, with a major market collapse. September 29, 2008, saw the DJIA fall over 777 points, making it one of the biggest single-day losses to date.
Causes:
- A subprime-mortgage-driven collapse in the housing market.
- Too much risk by financial institutions.
- Over-leveraging and complicated financial products, such as mortgage-backed securities.
Impact:
- The disaster caused a worldwide recession, widespread foreclosures, and a huge amount of wealth destruction.
- It also resulted in bailouts of major banks and reforms to try to regulate Wall Street and promote financial stability, like the Dodd-Frank Act.
COVID-19 Market Crash
When: March 2020
What Happened:
The COVID-19 pandemic led to an extraordinary stock market crash early on. The S&P 500 saw many trading pauses (circuit breakers), and the DJIA fell 30% within a matter of weeks.
Causes:
- Anxiety and apprehension about the pandemic’s effect on the economy.
- Lockdowns across the nation shuttered businesses and supply chains.
- Prosperity came to a sudden halt, and unemployment rates spiked.
Impact:
- This crash was swift but was followed by a surprisingly precipitous recovery.
- Due in no small part to government stimulus and interventions.
Lessons from Previous Stock Market Crashes
Diversification Is Key
One of the most reliable lessons from past market crashes is that diversification matters. Heavy concentrations in any one sector or stock can lead to such massive losses when the markets go south. Diversifying into different types of investments, from bonds to commodities to international markets, can lower risk.
Avoid Emotional Decisions
Panic selling in a down market can lock in your losses. Buying into speculative bubbles, on the other hand, usually transpires poorly. When times are tough, controlled and sound investment decisions are expected.
Keep a Long-Term Perspective
Markets generally bounce back eventually. For one, while the market crashes have been numerous, the S&P 500, for example, has had an average annual return of about 10% over the years. Having a longer-term view can also help to weather short-term volatility.
Learn from History
Investors who can understand the reasons for past crashes will recognize which warning signs they should heed in the future. For example, speculative bubbles and overleverage frequently lead the way.
Be Ready for the Unknown
Crashes are bound to happen, but their timing and severity are all but impossible to forecast. An emergency fund and a balanced portfolio can help mitigate the uncertainty.
Will Another Crash Happen?
Stock market crashes are a natural part of economic cycles. Whereas the timing of the next crash cannot be entirely predicted, historically (despite a lot of variability along the way) patient investors have been rewarded in financial markets. For the existing and potential investors, it’s all about knowledge and being prepared.
