Market Wrap: Thursday, October 8, 2026 — S&P 500, Nasdaq & Dow Jones

Today's market session was marked by a selloff, with the Nasdaq Composite leading the decline, down 1.25% and the S&P 500 falling 0.47%. The Dow Jones Industrial Average bucked the trend, rising 0.10%. The uneven performance was largely driven by the tech sector, with AI-related stocks struggling following a revenue setback at OpenAI. This led to a decline in the Nasdaq, which was also influenced by the sell-off in chip stocks. Oil prices rose, contributing to the overall market volatility, although they eased after comments from President Trump suggesting the US would not attack Iran before the midterm elections.

The market's risk-off tone was also exacerbated by concerns over the Middle East and hurricane worries, which drove up oil prices. Rapid bond yield movements have been a notable theme, with some analysts warning that such moves have preceded major financial blowups. The sell-off in AI stocks was particularly pronounced, with some firms experiencing significant declines. The market's mixed performance was also influenced by the Treasury yield retreat, which saw the Dow Jones Industrial Average waver. Overall, today's market session was characterized by a selloff, with the tech sector and oil prices being key drivers of the market's volatility.
