The Flash Crash refers to a sudden and extreme market downturn that occurred on May 6, 2010, in the U.S. stock market. During this event, major stock indices, including the Dow Jones Industrial Average, experienced a rapid and significant decline, followed by a swift recovery. The crash was characterized by a series of high-frequency trades and market anomalies, leading to a temporary disruption in liquidity. The exact cause of the Flash Crash is complex and involves algorithmic trading, liquidity issues, and a lack of market safeguards. Regulators and market participants have since implemented measures to prevent such incidents and enhance market stability.
