Why did investors sell off their stocks causing black Thursday?

Investors sold off their stocks on Black Thursday, October 24, 1929, due to widespread panic over declining stock prices and fears of an impending economic downturn. The market had experienced rapid growth and speculation, leading to inflated stock values. As stock prices began to fall, investors rushed to sell their shares to avoid further losses, triggering a massive sell-off that contributed to the onset of the Great Depression. This loss of confidence in the market created a cascade effect, leading to significant financial turmoil.
