Nvidia Deal Lifts Chip Stocks Amid Geopolitical Risks

A wave of semiconductor stocks rose in afternoon trading after Nvidia (NVDA) announced a strategic partnership and a $2 billion investment in fellow chipmaker Marvell Technology. Marvell shares jumped 6.9% on the news, while Nvidia stock also advanced, helping lift sentiment across the broader chip sector.

The collaboration is designed to connect Marvell to Nvidia’s artificial intelligence ecosystem through NVLink Fusion technology. This will allow customers greater flexibility in building advanced computing infrastructure, according to the companies’ announcement.

The size of Nvidia’s commitment and the focus on AI infrastructure highlighted what the articles described as rapid expansion and high‑stakes competition in the AI hardware market. The development supported investor confidence after a period of recent volatility in technology and semiconductor names.

Shares of multiple semiconductor companies traded higher in response to the Nvidia–Marvell announcement. The move affected names such as Allegro MicroSystems, Amkor, NXP Semiconductors, Photronics, Lam Research (LRCX), Microchip Technology, Monolithic Power Systems, onsemi, Vishay Intertechnology, Amtech, Power Integrations, Entegris and Penguin Solutions.

Analysts cited in the reports noted that the stock market can overreact to news and that large price swings may create opportunities in high‑quality names. Many of the companies mentioned are characterized as highly or extremely volatile, frequently posting daily moves greater than 5% over the past year.

Allegro MicroSystems and Entegris were highlighted as examples of stocks reacting positively to the Nvidia‑linked rally after sharp declines tied to geopolitical headlines. Allegro has recorded 33 moves greater than 5% in the past year, while Entegris has seen roughly 30–36 such moves.

Both stocks had dropped about 24 hours earlier as reports on the Iran war raised concerns over potential disruptions to semiconductor supply chains. The worries focused on essential gases such as helium, which are critical for chip fabrication.

Major foundries including Taiwan Semiconductor Manufacturing Company, Samsung Electronics and SK hynix were projected in those reports to face production challenges if gas supplies were constrained. Such issues could ripple into products ranging from Apple (AAPL) iPhones to Nvidia AI servers, contributing to a broader tech sell‑off and pushing the Nasdaq into correction territory.

onsemi was another beneficiary of the sector rebound following Nvidia’s announcement. Its shares are described as very volatile, with 29 moves greater than 5% over the past year. The latest rise came after a prior drop linked to escalating US–China trade tensions.

Four days earlier, onsemi had fallen 4.7% after China’s Ministry of Commerce launched two trade barrier investigations into US practices. The probes focus on alleged disruptions to global supply chains and on US policies restricting exports of advanced technology products to China and limiting bilateral investment.

These Chinese investigations were viewed in the reports as a response to US tariff investigations started earlier in the month, adding uncertainty for US technology companies with significant business exposure to the Chinese market.

Beyond its short‑term volatility, Entegris has gained 29.6% since the beginning of the year. At $116.26 per share, however, it remains 15.6% below its 52‑week high of $137.79 reached in February 2026.

A hypothetical $1,000 investment in Entegris five years ago would now be worth $1,038, according to the reporting. This underscores how, despite recent gains and sharp daily moves, longer‑term returns in some chip names have been comparatively modest.
