On what date did U.S. stocks suffer the 2015 Flash Crash?

U.S. stocks suffered the 2015 Flash Crash on August 24, 2015.

The session began with heavy selling in global markets, especially in China, and intensified when U.S. trading opened. The Dow Jones Industrial Average fell more than 1,000 points shortly after the open before recovering part of the loss. Hundreds of U.S. stocks also experienced unusually sharp intraday moves.

Concerns about China’s slowing economy, currency changes, and the outlook for global growth contributed to the selling. Market structure and temporary shortages of liquidity made price movements more disorderly.

This episode is sometimes confused with the 2010 Flash Crash, which occurred on May 6, 2010. The 2015 event also differed from the 1987 crash because it was a shorter, more intraday disruption rather than a single-day collapse of comparable scale.
