During the 2010 Flash Crash, about how many Dow Jones Industrial Average points vanished within minutes?

During the 2010 Flash Crash, nearly 1,000 Dow Jones Industrial Average points vanished within minutes.

On May 6, 2010, US stock markets experienced an exceptionally rapid sell-off and partial rebound. The Dow fell about 1,000 points, roughly 9%, in a matter of minutes before recovering much of the loss. Some individual securities briefly traded at wildly distorted prices, while several markets experienced major liquidity problems.

Investigations concluded that a large automated sell order in E-mini S&P 500 futures helped interact with high-frequency trading and other algorithmic activity. The exact mechanics were complex, but the episode showed how automated systems could amplify selling when available buyers became scarce. In 2015, trader Navinder Singh Sarao was charged in the United States; he later pleaded guilty to market manipulation and wire fraud.

The crash led exchanges and regulators to strengthen safeguards, including circuit breakers and limit-up-limit-down mechanisms. It was not a conventional economic crash caused by a recession or banking collapse. Instead, it was a market-structure shock that exposed the speed and fragility of modern electronic trading.
