Key Highlights

A broad rebound across major chipmakers drove the Nasdaq 100 higher on Tuesday, with the index gaining 1.7% as investors looked past recent concerns over stretched valuations in AI-related stocks. Nvidia Corp (NASDAQ: NVDA) rose 2.6%, Advanced Micro Devices Inc (NASDAQ: AMD) gained 7.7%, and Intel Corp (NASDAQ: INTC) advanced 6.0%, marking a strong session across the three largest US chipmakers.

The rally followed a period of investor caution around the semiconductor sector, as questions had emerged about whether valuations across AI-related stocks had run ahead of near-term earnings visibility, particularly given the scale of capital spending commitments from hyperscale cloud providers building out AI infrastructure. Tuesday's gains suggest that strong forward guidance from semiconductor producers has helped ease these concerns, at least for now.

AMD's 7.7% gain was the standout move among the three major chipmakers, potentially reflecting a combination of more attractive relative valuation following recent weakness and specific optimism tied to the company's data centre and AI accelerator product roadmap. Intel's 6.0% gain reflected similar sector-wide optimism, alongside continued investor interest in the company's foundry strategy and broader turnaround narrative.

Beyond the three largest names, the rebound extended across the semiconductor supply chain, with equipment makers and other chip designers including KLA Corp, Marvell Technology, and ON Semiconductor all posting solid gains on the same session. The breadth of the move across both design and equipment segments of the industry suggests the rally reflects a genuine improvement in sector-wide sentiment rather than a narrow, isolated catalyst.

The persistence of elevated hyperscaler capital spending on AI infrastructure remains a key factor underpinning the bullish case for chipmakers, even as some investors have periodically questioned whether the pace of spending can be sustained. Tuesday's gains suggest the market remains willing to extend the benefit of the doubt to this spending cycle, at least for the time being.

Looking forward, investor focus will likely turn to upcoming earnings reports from major chipmakers and hyperscale cloud providers for further confirmation of demand trends and capital expenditure plans, which will help determine whether Tuesday's rebound marks a durable shift in sentiment or a temporary reprieve from valuation concerns.
