On October 19, 1987, the Dow Jones Industrial Average plunged 22.6%, marking the largest single-day decline in history. An overheated market, the rise of program trading, and a chain reaction in global markets caused the crash to spread rapidly, triggering a global financial panic and leading to the establishment of subsequent stock market circuit breaker mechanisms.
To prevent severe market fluctuations in the future, the U.S. Securities and Exchange Commission has introduced a stock market circuit breaker mechanism to ensure market order. In addition, investors’ awareness of risks has significantly increased, and fintech and trading systems have been improved to strengthen risk control.
In recent years, events like the global stock market crash on March 9, 2020, caused by the pandemic, have been referred to by the media as “Black Monday,” indicating that this term has come to refer to any significant market turbulence on a Monday, reminding investors to remain vigilant about market risks.
The cryptocurrency market is highly volatile around the clock, with the risk of crashes similar to Black Monday being more common. Market sentiment spreads quickly, and automated risk control mechanisms in smart contracts, such as stop-loss settings, have become necessary defensive measures.
Historical lessons indicate that investment cannot ignore risks; rigorous stop-loss and capital management strategies must be established to avoid blindly following trends and to maintain a long-term investment perspective, calmly facing short-term fluctuations.
Black Monday is a wake-up call for market risk, reminding all investors that the market is unpredictable. Through sound risk management and rational judgment, one can steadily seize investment opportunities, whether in the stock market or the crypto market.
