During the 2010 Flash Crash, approximately how many Dow Jones points were erased in about 36 minutes?

During the 2010 Flash Crash, nearly 1,000 Dow Jones points were erased in about 36 minutes.

On May 6, 2010, U.S. markets suffered an abrupt plunge and partial rebound. The Dow Jones Industrial Average fell by about 1,000 points, roughly 9%, before recovering much of the decline. The episode began in the afternoon and unfolded far faster than a conventional panic, causing some individual stocks and exchange-traded products to trade at extremely unusual prices.

A joint investigation by U.S. regulators later concluded that a large automated sell order in E-mini S&P 500 futures interacted with high-frequency trading and liquidity conditions. The report described a feedback loop in which aggressive trading consumed available liquidity and intensified the fall. Investigators did not treat the event as a simple result of one trader acting alone.

The market recovered much of the loss the same day, but the crash prompted new safeguards. Exchanges later adopted coordinated pauses and rules designed to limit extreme price movements. The event is different from the 1987 crash because its most dramatic phase lasted minutes rather than a full trading day.
