A stock market crash is a sudden and significant decline in the value of stocks, often triggered by economic factors, investor panic, or unexpected news. During a crash, many investors may sell their shares rapidly, leading to a sharp drop in prices. This can result in substantial financial losses for individuals and businesses alike. Historically, stock market crashes have occurred at various times, such as the Great Depression in 1929 and the 2008 financial crisis. These events can have widespread effects on the economy, affecting employment, consumer spending, and overall market confidence.
