It was the most devastating stock market crash in the history of the United States, when taking into consideration the full extent and duration of its aftereffects.[1] The Great Crash is mostly associated with October 24, 1929, called Black Thursday, the day of the largest sell-off of shares in U.S. history,[2][3] and October 29, 1929, called Black Tuesday, when investors traded some 16 million shares on the New York Stock Exchange in a single day.[4] The crash, which followed the London Stock Exchange's crash of September, signaled the beginning of the Great Depression.
