What was the final major day of the 1929 Wall Street Crash, known as Black Tuesday?

Black Tuesday, the final major day of the 1929 Wall Street Crash, was October 29, 1929.

On that day, investors traded millions of shares while prices collapsed. The selling followed Black Thursday on October 24 and Black Monday on October 28. Although October 29 is the best-known date, the crash was a sequence of violent sessions rather than one isolated event.

The collapse followed years of speculative buying, extensive use of borrowed money, and optimism about rapidly rising share prices. The market decline damaged confidence, reduced wealth, and contributed to the severe economic contraction that became the Great Depression, although historians identify many additional causes.

Black Tuesday is not the same event as Black Monday in 1987. The 1929 crash involved the New York market during the beginning of a worldwide depression; the 1987 crash was much sharper in one-day percentage terms but did not produce a comparable depression.
