Black Tuesday was the 1929 stock-exchange panic day when about 16 million shares traded on the New York Stock Exchange.
Black Tuesday occurred on October 29, 1929. Sellers overwhelmed the market, and the Dow Jones Industrial Average fell approximately 12 percent. The trading volume was extraordinary for the period and became one of the most memorable statistics of the Wall Street Crash.
Black Tuesday followed Black Thursday on October 24 and another severe decline on Black Monday, October 28. The sequence is often compressed into a single “1929 crash,” but the separate dates describe different trading sessions and different losses.
The crash did not alone cause every feature of the Great Depression. Banking failures, reduced lending, deflation, falling production, unemployment, international debt problems, and trade contraction all shaped the economic catastrophe that followed. The Dow continued declining until 1932, so October 29 was a landmark rather than the final market low.
