What was the principal U.S. stock exchange where the 1929 Wall Street Crash unfolded?

The principal U.S. stock exchange where the 1929 Wall Street Crash unfolded was the New York Stock Exchange. Located at 11 Wall Street in Manhattan, it was the central venue for trading many of the major American companies of the period.

The exchange experienced extraordinary trading volume as investors rushed to sell shares in October 1929. On October 24, October 28, and October 29, selling pressure became especially intense, helping create the sequence remembered as Black Thursday, Black Monday, and Black Tuesday.

The New York Stock Exchange was not the cause of every problem behind the crash. Speculation, purchases made with borrowed money, uneven economic growth, and weaknesses in the banking system all contributed to the collapse.

The Nasdaq did not exist in 1929; it began operations in 1971. The American Stock Exchange was also a separate exchange, historically associated with smaller companies and different listings.
