Chip stocks fall as investors reassess Nvidia's role after Huang's exit

what happened

Dow Jones Newswires reports that chip shares reversed course on Friday after a strong start to the week. The PHLX Semiconductor Index (SOX) had climbed 10.6% over the first four days of the trading week, as traders bet that a weaker Nvidia would open room for rivals and give suppliers more pricing power. Jensen Huang stepped down as Nvidia's chief executive on Thursday morning.

The index fell 3.6% on Friday as investors weighed the fact that Nvidia and Huang played a dual role, supplying chips while also underpinning the AI industry financially. AMD, which had rallied right after the resignation, dropped 9% and ranked among the weakest names in the S&P 500. Sandisk lost 7%, Broadcom, Intel and Micron slipped between 3% and 5%, and Dell fell nearly 8%.

why it matters

The sell-off shows how closely the chip sector's gains have been tied to Nvidia's standing in AI. Nvidia's board has opened an investigation into whether a relationship involving Huang compromised business secrets, and analysts say the company could lose its role as a financial anchor for the AI industry, with effects spreading across tech.
