Market Wrap: Thursday, October 15, 2026 — S&P 500, Nasdaq & Dow Jones

Today's market session saw a mixed performance across major indices, with the Dow Jones Industrial Average leading the charge, rising 1.08% to close the day. In contrast, the Nasdaq Composite managed to trim its losses, ending the day with a gain of 0.08%, while the S&P 500 posted a more modest 0.33% increase. The uneven performance suggests that investors are rotating out of riskier assets, particularly those related to artificial intelligence (AI), in response to a sell-off in AI-related stocks.

The most significant macro driver of today's market session was the decline in Treasury yields, which sank in response to the hot inflation report. This led to a flight to safety, with investors seeking refuge in government bonds. The drop in Treasury yields also contributed to a rally in the Dow, which rose by over 500 points. Notably, the market's shift away from AI-related stocks and towards safer assets suggests a risk-off tone, with investors becoming increasingly cautious in the face of economic uncertainty. The performance of the S&P 500, which was dragged down by hot inflation data and sell-off in AI-related stocks, underscores the mixed nature of today's market session.
