The U.S. stock-market crash day that occurred on October 29, 1929, after Black Thursday and Black Monday, was Black Tuesday.
Selling intensified after the market’s earlier breakdown on October 24 and October 28. On October 29, investors sold millions of shares, prices plunged, and the New York Stock Exchange recorded extraordinary trading activity for the period.
Black Tuesday is widely used as the symbolic endpoint of the Wall Street Crash of 1929, although the market continued falling afterward. The Dow Jones Industrial Average did not reach its eventual low until July 1932.
The crash did not single-handedly cause every aspect of the Great Depression. It damaged wealth and confidence, while bank failures, debt problems, falling demand, and policy decisions deepened the economic downturn. Black Tuesday is distinct from Black Thursday and Black Monday, the earlier crash days in the same episode.
