Chip Stocks Surge as AI Hardware Demand Lifts Nasdaq
US semiconductor stocks staged a broad rally on Tuesday, with the Philadelphia Semiconductor Index climbing 4% and helping lift the tech-heavy Nasdaq Composite to a 1.18% gain. The S&P 500 rose 0.6% while the Dow Jones Industrial Average added just 0.03%, a split that underlined how much of the day’s momentum came from chip and hardware names rather than the wider market.
Advanced Micro Devices led the large-cap chipmakers with a 6.03% advance, while Broadcom rose 4.61%, Intel gained 4.05%, Micron added 3.52% and Qualcomm put on 2.02%. Taiwan Semiconductor Manufacturing Co. and ASML, two of the industry’s key equipment and foundry suppliers, each rose more than 3%. Nvidia, the largest chip company by market value, lagged the group with a 1.13% gain but still added to the session’s positive tone.
The strength extended into storage and optical-communications suppliers, the less glamorous corners of the AI supply chain. Western Digital rose more than 6%, while Seagate Technology and SanDisk each gained more than 3%. Lumentum advanced more than 5%, Coherent more than 6% and Marvell Technology more than 4%. Those companies make the memory and optical components that sit inside data centers handling heavy AI workloads, and their moves suggested investors were looking beyond the headline chip names.
Oracle was another focal point. The enterprise software company rose 3.56% after expanding partnerships with Google, Intel and Nvidia. Intel’s 3.6% gain came on the same day. Cerebras, the AI chip startup that competes with Nvidia in specialized processors, jumped more than 10%, extending a run of enthusiasm for companies positioning themselves around AI computing.
The rally was not confined to semiconductors. Solar names also drew buyers. Daqo New Energy rose 8.3% and Canadian Solar gained 9.2%, while JinkoSolar added 1.9%. The moves came alongside a modestly higher close for the Nasdaq Golden Dragon China Index, which finished down 0.1% on an initial basis, a sign that the buying in US tech did not translate evenly into Chinese listings traded in New York.
Among individual Chinese ADRs, the picture was mixed. Vianet Group fell 3.9%, NetEase lost 3.6% and Hesai dropped 2.6%. Alibaba finished roughly flat, while Pinduoduo added 0.3%, Baidu rose 0.5%, JD.com gained 1.3%, Xpeng rose 1.6% and JinkoSolar added 1.9%. The Livermore China ADR Leaders Index, a gauge of prominent Chinese companies listed in the US, closed up 0.93%, with Akso Health up 11.02%, Brain Regeneration Technology up 9.62% and Silicon Motion Technology up 7.99%.
The session’s message was that AI infrastructure spending remains the dominant theme for equity investors, even as questions swirl about how long the cycle can run. When memory makers, optical suppliers and chip designers all move higher together, it usually reflects expectations about future data-center buildout rather than near-term consumer demand. The fact that smaller names like Cerebras and the storage specialists outperformed Nvidia suggests money is rotating into second-order beneficiaries of the same trend.
For global readers, the takeaway is less about any single company than about the market’s appetite for hardware that powers AI. That appetite has been volatile this year, with sharp selloffs followed by quick recoveries. Tuesday’s broad advance, spanning chips, storage, optics and solar, showed investors willing to buy the ecosystem rather than just the leader. Whether that confidence holds will depend on the next round of earnings and on whether orders for AI equipment keep pace with the optimism now priced into these shares.
