During the 2010 Flash Crash, approximately how many Dow Jones points were lost intraday?

During the 2010 Flash Crash, the Dow Jones Industrial Average lost nearly 1,000 points intraday.

On May 6, 2010, the Dow fell about 1,000 points in a matter of minutes, representing roughly 9% of its value at the low. It recovered much of the loss before the session ended, making the event unusually abrupt and partly reversible.

The episode involved a combination of market stress, automated trading, and rapidly changing liquidity. A later U.S. investigation concluded that a large automated sale of futures contracts by trader Navinder Singh Sarao contributed to the conditions, although the broader market structure helped amplify the movement.

The Flash Crash differed from a conventional crash that develops over days or months. It prompted changes to trading safeguards, including circuit breakers and rules designed to pause trading during extreme price moves.
