Semiconductors Pressured as China Rejects Nvidia Chips Amid Trade Tensions

The semiconductor sector faces a new headwind as geopolitical tensions and export policy uncertainty collide with growth expectations. China formally rejected NVIDIA chips despite US government approval for select sales, signaling Beijing's pivot toward homegrown semiconductor alternatives and potential retaliatory trade restrictions. Simultaneously, the US had approved H200 chip exports to 10 Chinese companies, creating a confusing and contradictory policy environment that traders are struggling to price. This mixed messaging from Washington, combined with Beijing's rejection stance, has sparked questions about whether semiconductor earnings forecasts adequately priced in China as a growth driver.

NVIDIA and AMD both faced acute selling pressure on May 15, with NVIDIA down 2.2 percent and AMD declining 3.3 percent, despite their dominant market positions and AI tailwind. The declines reflect a realization among investors that China policy is now a live variable in semiconductor valuations. For years, market participants had assumed that China export restrictions were a known constraint; the new dynamic is that even approvals come with geopolitical baggage, and China can unilaterally reject US technology regardless of policy shifts. This introduces a new layer of regulatory and geopolitical risk that was previously discounted.

The broader semiconductor earnings cycle is entering a critical phase, with AMD, NVIDIA, AVGO, and others preparing to report quarterly results over the next two weeks. Analysts on the tape cited supply chain concerns, fab capacity constraints, and the potential that some customers may be forced to source memory and logic chips from non-US suppliers if export restrictions tighten further. Arista Networks supply chains, for example, are noting that AMD may be positioned to supply 20-25% of deployments going forward, but AVGO chips may present a constraint given geopolitical risks. The earnings outlook is now bifurcated: companies with heavy China exposure face valuation pressure, while those with diversified or US-centric customer bases may hold up better.

The risk scenario is clear: if US-China trade tensions escalate further or if export controls broaden beyond current high-end AI chips, semiconductor makers face an upside earnings miss as China accelerates alternative sourcing. Conversely, if policy stabilizes and China begins accepting US chip sales again, the selloff offers a buying opportunity. Near-term volatility is likely through earnings season and any Trump-Xi follow-up negotiations around semiconductor trade-offs. The May 15 sell-off also reflects broader equity stress from the bond selloff, but the China story is a name-specific headwind that will linger.
