Which 1929 stock-market crash began on Black Tuesday, October 29?

The 1929 stock-market crash that began on Black Tuesday, October 29, was the Wall Street Crash of 1929.

The crash followed a speculative boom in United States shares during the 1920s. Many investors bought stock with borrowed money, increasing both potential gains and potential losses. Prices reached a peak in September 1929 before confidence weakened.

Black Thursday came on October 24, followed by renewed selling on October 28 and the dramatic fall on Black Tuesday. The crash did not by itself cause the entire Great Depression, but it damaged banks, businesses, and household wealth and intensified the economic downturn.

A common mix-up is treating Black Tuesday as the only day of the crash. It was the most famous session in a sequence of severe market declines in late October 1929.
