US Chip Stocks Tumble as Nvidia Bucks the Trend with 3% Surge
US chip stocks fell sharply on September 28, with ARM, Qualcomm, and others dropping over 3%, due to concerns about AI development slowdowns and rising Treasury yields. Nvidia (NVDA) rose 3% after announcing a $150B share buyback increase. The broader market also declined, with the S&P 500 down 0.51%.

Why it matters
The sector decline suggests short‑term pressure on most chip makers, while Nvidia's sizable buyback could attract buying interest and limit its downside.
Market read
The news combines a material corporate action (Nvidia buyback) with a sector‑wide risk event, offering both potential upside for Nvidia and downside risk for other chip stocks.
What to watch
Potential slowdown in AI model training may temper demand, but Nvidia's cash generation remains strong.
