US Stocks Edge Lower on Chip Sector Concerns, Tuesday, October 13, 2026

Market Wrap

US stocks finished mixed on Tuesday, October 13, 2026, as weakness in semiconductor shares weighed on the technology-heavy Nasdaq Composite. The S&P 500 edged lower, while the Dow Jones Industrial Average advanced.

The Nasdaq Composite closed lower for the day, and the S&P 500 finished barely lower. The PHLX chip index declined for a fifth consecutive session.

What Drove It

Semiconductor weakness drove much of Tuesday’s trading. Investors remained concerned about rising competition and questioned the scale of artificial intelligence (AI) spending. Reports of technological advancements by Chinese memory chip company CXMT added to competitive concerns. Broadcom CEO Hock Tan also compared some investment flowing into the sector to “casino gambling.” Chip stocks extended recent losses across the globe.

Investors also weighed the first third-quarter corporate earnings reports from big US banks. Results were mixed. Citigroup and Johnson & Johnson reported higher profits, but both stocks slipped. Analysts anticipate S&P 500 third-quarter earnings to show an increase of over 30%.

Geopolitical developments continued to affect commodity markets. Oil prices rallied for a second consecutive day following attacks on a Saudi airport over the weekend, a move that likely influenced broader market sentiment. Treasury yields dipped as investors sought safety.
