The 2010 Flash Crash took place on which date?

The 2010 Flash Crash took place on May 6, 2010.

During that U.S. trading session, major stock indexes plunged and then recovered much of the loss within minutes. The Dow Jones Industrial Average briefly fell about 1,000 points, an unusually rapid move for a market of that size. Many individual securities also experienced extreme, short-lived price swings.

Investigations by U.S. regulators concluded that a large automated sell order, combined with high-frequency trading and stressed market conditions, helped trigger and amplify the plunge. The event exposed how interconnected electronic markets had become and raised questions about liquidity that disappears during sudden stress.

The Flash Crash differed from a conventional bear market because it was exceptionally fast and much of the decline reversed the same day. Regulators later introduced measures such as circuit breakers and trading pauses to reduce the risk of similar disorderly moves.
