The 1929 U.S. stock-market crash day immediately after Black Monday was called Black Tuesday.
Black Tuesday fell on 29 October 1929. About 16 million shares changed hands on the New York Stock Exchange, a record at the time, as investors rushed to sell. The Dow Jones Industrial Average dropped roughly 12 percent, following a fall of about 13 percent on Black Monday, 28 October.
The crash developed after years of heavy speculation, margin buying, and rapid expansion in share prices during the 1920s. The market’s collapse did not single-handedly cause the Great Depression, but it intensified financial stress and damaged confidence. Bank failures, falling production, unemployment, and international economic problems followed.
Black Tuesday is distinct from Black Thursday, 24 October 1929, which is often identified as the first major panic day of the crash. The phrase “Black Tuesday” specifically refers to the climactic selling session on 29 October.
