Market Crashes: The Great Depression (1929) The amount the market declined from peak to bottom: A string of terrible days led to a more than 40% drop in the market from the beginning of September 1929 to the end of October 1929. In fact, the market continued to decline until July 1932 when it bottomed out, down nearly 90% from its 1929 highs.
The 1930 Wall Street crash would propel the market downward, and the trend would continue until the market bottomed out in 1932. As the stock market and the economy fed on the problems of the other, the fall of 1930 saw the unavoidable signs of depression take hold of the US, almost a full year after the initial crash. The 1929 and 1930 Wall Street crash served to weaken investor confidence, as well as caused a drop in trading volume.
