Answer:
During the 1920s, the U.S. stock market underwent rapid expansion, reaching its peak in October 1929 after a period of wild speculation during the roaring twenties. By then, production had already decreased and unemployment had risen, leaving stocks in great excess of their real value. Among the other causes of the stock market crash of 1929 were low wages, the proliferation of debt, a struggling agricultural sector and an excess of large bank loans that could not be liquidated.
