Market Wrap: Thursday, November 5, 2026 — S&P 500, Nasdaq & Dow Jones

Today's stock market session was marked by a broad selloff, with all major indices posting significant losses. The Nasdaq Composite led the decline, plummeting 5.52% to erase gains from the post-election rally. The Dow Jones Industrial Average and S&P 500 also suffered substantial losses, falling 3.44% and 4.36% respectively. The Dow's 1,800-point drop was particularly notable, with volatility spiking as investors ditched chip and data-center stocks. The Nasdaq's tumble into correction territory was also a concern, driven by fears of AI regulations and the impact on AI tech stocks.

The selloff was largely driven by concerns over AI regulations and their potential impact on the tech sector. The Nasdaq's heavy weighting in chip and data-center stocks made it particularly vulnerable to the sell-off. The S&P 500's decline was also influenced by the tech sector, with the index's tech-heavy composition contributing to its losses. The Dow's decline was more broad-based, with losses across various sectors. The overall tone of the market session was decidedly risk-off, with investors seeking safety in a tumultuous environment. The sharp reversal from the post-election rally gains was a notable theme, highlighting the market's sensitivity to policy developments and regulatory changes.
