Semiconductor Rally Stalls as China Export Restrictions Resurface; AMD, NVDA Dip on Geopolitical Jitters

Semiconductor equities experienced a volatile session on May 15 as geopolitical risks flared and China export policy concerns resurfaced. The session opened with weakness in Asian markets, particularly Samsung, which declined sharply amid North Korean tensions. This spillover pressure hit US chip names hard in overnight trading, with AMD falling 3.3% and NVDA declining 2.2% before the market opened. The move reflected trader anxiety that elevated geopolitical risk in Asia could lead to further restrictions on chip exports to China or allied nations, precisely opposite to the earlier H200 approval narrative.

One social media commentator posed a critical question: 'Do you think being able to sell to China was priced into some of these semis?' This uncertainty reveals a tension within the semiconductor trade. Yes, the H200 approval removes one category of restriction, but the broader US-China tech war remains live. Taiwan, the world's leading semiconductor manufacturing hub, is a flashpoint. Any escalation in North Korea-South Korea tensions or cross-strait dynamics could force the US to impose new restrictions, offsetting the gains from the H200 approval. Investors, burned by prior policy reversals, are pricing in this tail risk.

Meanwhile, memory chip stocks continue to defy traditional valuation logic. Despite chip prices soaring and sentiment running hot on AI capex cycles, some memory names like MU and others have become cheaper to own on a price-to-earnings basis even as share prices have climbed sharply. This apparent paradox reflects the market's difficulty in pricing sustainably high memory demand versus recession risk from the global bond selloff and inflationThe rate at which prices rise across an economy. squeeze. Arista Networks (ANET) was noted as possibly the next company to gain Oracle as a customer, but its supplier ecosystem remains fragmented, with AMD potentially capturing only 20-25% of deployments and Broadcom (AVGO) chips presenting capacity constraints.

The core issue: chip valuations are caught between AI enthusiasm and macro caution.

Semiconductor investors should watch for clarity on whether the H200 approval signals a broader US-China rapprochement or remains a tactical carve-out.
