During the 1929 Wall Street Crash, what was the name of the final major panic day?

The final major panic day of the 1929 Wall Street Crash was called Black Tuesday.

Black Tuesday took place on October 29, 1929, when investors sold roughly 16 million shares on the New York Stock Exchange. The selling followed Black Thursday and Black Monday, and it confirmed that the market’s earlier speculative boom had broken down.

The crash had been preceded by rapid increases in stock prices, widespread margin buying, and optimism that rising values would continue indefinitely. When prices fell, investors who had borrowed money faced demands for additional cash or collateral. Forced selling added pressure to an already frightened market.

Black Tuesday did not mark the end of the decline. U.S. share prices continued falling for several years, and the Dow reached a much lower bottom in 1932. The broader economic collapse also involved bank failures, reduced lending, falling production, and unemployment. It is inaccurate to treat one day as the sole cause of the Great Depression, although Black Tuesday became its most famous market symbol.
