Answer:
The average stock price dropped by about 80% between 1929 and 1932 during the Great Depression.
Step-by-step explanation:
The stock market crash of 1929 triggered the Great Depression, which was a severe and prolonged economic downturn that lasted throughout the 1930s. During this period, the average stock price dropped by approximately 80%, reaching its lowest point in 1932. This decline in the stock market had far-reaching effects on the economy, leading to high levels of unemployment, bank failures, and widespread poverty. It was only after World War II that the U.S. economy began to recover and the stock market regained its pre-Depression levels.
