On what date did Black Tuesday, the final major sell-off of the 1929 Wall Street Crash, occur?

Black Tuesday, the final major sell-off of the 1929 Wall Street Crash, occurred on October 29, 1929. On that day, roughly 16 million shares changed hands on the New York Stock Exchange, a record at the time, as investors rushed to sell.

The date followed Black Thursday on October 24 and Black Monday on October 28. Although the market had already fallen sharply, the Tuesday collapse intensified public fear and became the crash's most famous day. The Dow Jones Industrial Average fell about 12% on October 28 and nearly 12% again on October 29.

The crash did not by itself create the entire Great Depression, but it damaged confidence, reduced wealth, and exposed weaknesses in banks and businesses. A common mix-up is treating Black Tuesday as the beginning of the crash; the market's decline had already started in September 1929.
