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.
Many investors became convinced that stocks were a sure thing and borrowed heavily to invest more money in the market. But in 1929, the bubble burst and stocks started down an even more precipitous cliff. In 1932 and 1933, they hit bottom, down about 80% from their highs in the late 1920s. This had sharp effects on the economy. Demand for goods declined because people felt poor because of their losses in the stock market.
