Which 1929 U.S. stock-market crash day is known as Black Tuesday?

Black Tuesday, the most famous day of the 1929 U.S. stock-market crash, occurred on October 29, 1929.

On that Tuesday, investors traded millions of shares on the New York Stock Exchange as prices collapsed. The selling followed Black Thursday, October 24, and Black Monday, October 28. Although the crash did not by itself create the entire Great Depression, it became its best-known financial symbol and severely damaged confidence in banks, businesses, and investment.

The market had risen dramatically during the 1920s, encouraged by speculation and widespread buying on margin. Many investors had borrowed money to purchase shares, so falling prices created demands for additional cash and forced more selling. The Dow Jones Industrial Average continued falling after Black Tuesday and did not reach its pre-crash peak again until 1954. Black Tuesday is sometimes confused with Black Monday, but the two dates were consecutive stages of the same historic collapse.
