On what date did the 1929 Wall Street Crash’s most famous “Black Tuesday” trading session occur?

The 1929 Wall Street Crash’s famous “Black Tuesday” trading session occurred on October 29, 1929.

The day followed “Black Thursday,” October 24, and “Black Monday,” October 28, as panic selling spread across the New York Stock Exchange. On October 29, about 16 million shares changed hands, a record at the time, while prices fell sharply. The Dow Jones Industrial Average lost almost 12% in one session.

The crash did not cause the entire Great Depression by itself. It was one part of a wider economic breakdown involving bank failures, falling investment, deflation, reduced consumer demand, and international financial problems. The Dow had peaked in September 1929 before losing most of its value over the following years.

A common mix-up is treating Black Tuesday as the only crash day. Several October sessions were severe, but October 29 became the best-known symbol of the 1929 collapse because of its extraordinary trading volume and widespread public attention.
