- Nvidia fell while AMD gained about 13%, and the S&P 500 had its strongest session since April 8.
Lead
Broadcom shares rose almost 9% on Monday, Nov. 9, as AI stocks recovered from the sharpest weekly slide in the semiconductor sector since early April 2025. The Philadelphia Semiconductor Index gained more than 6%, and the iShares Semiconductor ETF (SOXX) jumped 7.2%, its best day since July 30. The move reversed much of the prior week's damage, when the sector lost more than 12% on worries over AI spending and the political outlook after the U.S. midterm elections.What Happened to Broadcom Shares?
Broadcom shares closed at $319.48, a gain of $25.79 on the session, or 8.78%. The rise made the semiconductor and infrastructure software company one of the two largest positive contributors to the chip index. The other was Advanced Micro Devices (AMD), which surged about 13%.
The advance extended across the sector. Semiconductor equipment and component makers including Applied Materials (AMAT) also posted sharp gains, as buyers returned to names that had been sold hardest during the previous week.
Why Did Chip Stocks Rebound?
Chip stocks rebounded because the drivers of the prior week's selloff eased on Monday. Investors had sold technology shares on concern that a Democratic-controlled Congress could slow data center construction and tighten oversight of AI development. The prevailing view on trading desks was that the reaction overshot, given the uncertainty over what legislation would actually pass.
Macro conditions also helped. Oil prices fell about 4% after signals that further U.S. strikes on Iran were unlikely, which eased inflation worries. All 11 S&P 500 sectors finished higher.
How Did the Broader Market Respond?
The broader market rallied alongside semiconductors. The S&P 500 rose 2.41% to 7,554.67, its strongest daily gain since April 8. The Dow Jones Industrial Average added 1,131.81 points, or 2.21%, to 52,417.54. The Nasdaq Composite gained 2.67% to 25,235.49.
Breadth was strong. Advancing issues outnumbered decliners by 4.46 to 1 on the New York Stock Exchange and 3.56 to 1 on the Nasdaq.
Nvidia Lags the Rally
Nvidia (NVDA) was the only decliner in the chip index. Its shares fell and closed at their lowest level since April 7, as reports of an investigation into whether CEO Jensen Huang had been targeted by a foreign intelligence effort added pressure. The divergence left the largest AI chip supplier trailing a rebound led by Broadcom and AMD, which supply custom accelerators and data center processors.What Comes Next for Chip Stocks?
The next test for chip stocks is a run of data points on inflation and data center demand. The October Consumer Price Index is due Tuesday, followed by the Producer Price Index on Friday. Both will shape expectations for the Federal Reserve's December meeting.
Earnings from CoreWeave (CRWV), Cisco (CSCO) and Applied Materials are due in the coming days. They will give a read on whether spending on AI infrastructure is holding up. Broadcom reports fiscal fourth-quarter results in December, and its guidance on AI revenue is the next company-specific catalyst for the stock.
Outlook
Monday's session recovered a large part of the previous week's chip losses, but the sector remains below its pre-selloff levels. The questions that drove the decline remain open: how fast AI infrastructure spending can grow, and how Washington will treat data center expansion. Inflation data this week and the coming earnings from AI infrastructure suppliers are the nearest checkpoints.
