What date was Black Tuesday, the second major New York Stock Exchange crash day in 1929?

Black Tuesday, the second major New York Stock Exchange crash day in 1929, occurred on 29 October 1929. The date followed Black Monday and marked one of the most dramatic sessions of the Wall Street Crash.

On Black Tuesday, investors traded millions of shares while prices collapsed. The panic followed years of speculative buying, widespread use of borrowed money, and growing concern that stock prices had risen far beyond underlying business values. The market's decline continued after the famous October dates and reached a low in July 1932.

Black Tuesday is often confused with Black Thursday, 24 October, the first major panic day, or Black Monday, 28 October. The four October labels describe different sessions in the same crash. The Wall Street Crash contributed to the financial instability of the Great Depression, although the Depression had multiple causes.
