Which 1929 Wall Street crash day, on October 29, became known as Black Tuesday?

The 1929 Wall Street crash day on October 29 became known as Black Tuesday. It was the most famous selling day of the Wall Street Crash of 1929, which followed years of rising share prices and heavy speculation in the United States.

On Black Tuesday, investors traded roughly 16 million shares on the New York Stock Exchange, a record at the time. Prices plunged as confidence broke, and the Dow Jones Industrial Average lost about 12 percent. The panic did not create the entire Great Depression by itself, but it became its defining financial symbol.

Black Tuesday is sometimes confused with Black Thursday, October 24, when the first major wave of panic selling struck. Black Monday is usually associated with the 1987 global market crash, not 1929. The 1929 crash continued after October 29, and the Dow eventually reached a low in July 1932.
