AI Stocks Tumble as US 10-Year Yield Hits 5% and Oil Tops $100

Key Facts

1Semiconductor and data center stocks saw sharp declines exceeding 7% for several major firms including Corning and Astera Labs.

2The US 10-year Treasury yield reached 5% for the first time since October 2023.

3Crude oil prices rose to close above $100 per barrel amid ongoing geopolitical risks.

Amid escalating concerns over AI valuations, financial markets experienced intense selling pressure specifically targeting semiconductor and data center infrastructure firms. According to reports, major companies including Corning and Astera Labs saw sharp declines exceeding 7%, while the 10-year US Treasury yield reached the 5% threshold for the first time since October 2023. This downturn coincided with crude oil prices closing above $100 per barrel, heightening inflationary fears ahead of upcoming Federal Reserve meetings.

This pressure on the tech sector comes as markets reassess growth assumptions, with investor sentiment dampened by rising yields that increase borrowing costs for high-growth companies. Per market data, Corning (GLW) closed at $166.40 and Astera Labs (ALAB) at $291.22 as of the September 11, 2026 close. The declines extended to other sector peers such as Super Micro Computer (SMCI), which closed at $40.10, and Vertiv (VRT) at $257.06, reflecting a broad sell-off across Nasdaq components.

Looking at recent price action, the Nasdaq index (NDAQ) stood at $91.19 as of the September 11, 2026 close, while traders watch for yield stabilization around key psychological levels. Regarding upcoming catalysts, the economic calendar shows no immediate sector-specific events, but markets will remain sensitive to any Federal Reserve commentary on interest rate paths given that oil prices remain sustained above the $100 mark.
