S&P 500 Experiences Significant Single-Day Drop Near Record Highs
The S&P 500 fell 4.36% on November 5, marking its worst single-day performance since April 2025. The decline was particularly notable because it occurred while the index was trading within 2% of its October record high. The sell-off was primarily driven by a sharp contraction in technology and semiconductor stocks, with the Philadelphia Semiconductor Index dropping approximately 12% due to poor chipmaker earnings and political uncertainty regarding AI data center regulations. Historical analysis shows that such drops from near-record levels are rare; since 1950, only two other instances occurred where a 4% drop followed an index trading within 2% of its record. While the broader historical trend for 4% daily drops suggests a high probability of recovery—with the index rising in 47 out of 56 cases over the following year—the specific subset of drops occurring near market peaks has historically yielded more modest median gains of around 7%.
