During the 1929 Wall Street Crash, which date is commonly called Black Tuesday?

October 29, 1929, is the date commonly called Black Tuesday during the Wall Street Crash.

On Black Tuesday, approximately 16 million shares changed hands on the New York Stock Exchange, a record at the time. Prices plunged as investors rushed to sell, and the episode became the most famous day of the 1929 market collapse. The crash had already begun with Black Thursday on October 24 and continued after October 29 rather than ending instantly on that date.

The disaster shattered confidence in heavily speculative stocks and contributed to a long bear market. The Dow Jones Industrial Average did not reach its eventual low until July 1932. Historians generally describe the Great Depression as the result of several interacting causes, so Black Tuesday should not be treated as a complete explanation by itself.
