On what date did the Dow Jones Industrial Average suffer the famous 1929 “Black Tuesday” crash?

The Dow Jones Industrial Average suffered the famous 1929 “Black Tuesday” crash on October 29, 1929.

Black Tuesday followed Black Thursday, October 24, when heavy selling first shocked Wall Street. The market briefly stabilized, but confidence continued to deteriorate over the next several sessions. On October 29, investors traded roughly 16 million shares, then an extraordinary volume, while the Dow fell nearly 12%.

The crash did not single-handedly cause the Great Depression. It exposed excessive speculation, buying stocks on margin, weak banking practices, and a broader economic slowdown. The Dow continued falling after October 1929 and eventually reached its bear-market low in July 1932.

Black Tuesday is sometimes confused with Black Monday, the name used for the 1987 global stock-market crash. Black Thursday and Black Tuesday were separate days within the 1929 Wall Street collapse.
