The economic conditions on Black Thursday (October 24, 1929), a key event in the lead-up to the Great Depression, were primarily influenced by many investors selling their shares of stock.
On that day, a panic selling frenzy occurred as investors began to lose confidence in the market. This massive sell-off led to a sharp decline in stock prices, which triggered further panic and more selling. While other factors, such as speculation and overextension in the stock market, contributed to the overall economic environment, the immediate issue on Black Thursday was the large number of investors trying to exit the market, leading to a significant drop in stock prices.
