U.S. stock markets experienced significant volatility over the past week, culminating in a chaotic trading session on Friday. The S&P 500 fell 3.46% on Thursday, while the Dow Jones Industrial Average dropped 1,014.79 points, or 2.5%. The tech-heavy Nasdaq also ended lower, down 4.31%. This followed a remarkable rally on Wednesday, where the S&P 500 surged 9.52%, marking its third-largest single-day gain since World War II. Despite the tumultuous week, the S&P 500 managed to gain 1.8% on Friday, ending the week amidst ongoing concerns regarding trade war escalations. Historical data indicates that following a significant one-day loss, the S&P 500 has typically dropped an average of 1.3% in the subsequent week, a trend that has only been matched during the Great Depression. Analysts note that in the past, only three out of 16 instances where the S&P 500 fell 15% or more during a year resulted in a positive year-end finish, suggesting that recovery from such declines is rare.
