During the 1929 Wall Street Crash, October 24, 1929, became known as Black Thursday after heavy selling began.
The Dow Jones Industrial Average fell sharply that day as trading volume surged and investors rushed to sell shares. Major bankers met afterward to discuss measures intended to restore confidence, but the selling pressure returned in the following days.
Black Thursday is often confused with Black Monday and Black Tuesday, the two later sessions in October that produced even steeper losses. Black Tuesday, October 29, is commonly treated as the crash’s most infamous day, but the panic began several trading days earlier.
The crash followed a period of heavily leveraged speculation in U.S. shares. Its consequences extended beyond Wall Street, contributing to the broader economic contraction known as the Great Depression.
