On July 13, the semiconductor sector experienced a sharp decline, with escalating geopolitical tensions serving as one of the primary drivers. It is not surprising that many investors, concerned that further deterioration of the Middle East conflict could weigh on the broader equity market, chose to lock in profits. However, for capital with a long-term investment horizon, the current volatile period presents a favorable opportunity to position in top-tier semiconductor stocks. Among them, Nvidia (NVDA) and Marvell Technology (MRVL) merit particular attention.
Why It Matters: The Long-Term Prosperity Trend Remains Intact
The sell-off appears to be a temporary reaction to geopolitical risk rather than a fundamental shift in AI semiconductor demand. Nvidia trades at a forward price-to-earnings ratio of 24.1 times, only slightly above the information technology sector average of 21.7 times. Despite its astonishing rally over the past several years, the company still has significant upside potential as AI infrastructure spending continues to grow. Nvidia is no longer merely a GPU company; its product portfolio now covers multiple layers of the AI stack, including the standalone Vera CPU. Furthermore, Nvidia has recently increased its per-share dividend significantly and committed to returning at least 50% of its free cash flow to shareholders through dividends and buybacks, enhancing its long-term investment appeal.
Our Interpretation: Marvell as a Gateway Between Two Ecosystems
What makes this story particularly compelling is the dual investment line formed by Nvidia and Marvell. Marvell is a leading manufacturer of application-specific integrated circuits (ASICs), having designed Amazon’s Trainium chips. Amazon is now exploring selling those chips to other data center operators, signaling robust demand for custom AI silicon. Alphabet has also indicated it will sell its custom AI chips externally. These developments are positive for Marvell. More intriguingly, Marvell supports the UALink open interconnect standard, an alternative to Nvidia‘s proprietary NVLink, while simultaneously having received a $2 billion investment from Nvidia in March 2026 and forming a strategic partnership covering NVLink Fusion-compatible networking, optical interconnects, and silicon photonics. This positions Marvell as a unique player that can serve both ecosystems, potentially becoming more valuable precisely because it bridges the two worlds.
Benefits and Risks: Who Gains and Who Loses
- Nvidia (NVDA): As the dominant GPU maker, Nvidia continues to benefit from high switching costs and a wide moat. However, the spread of UALink could erode NVLink’s exclusivity over time.
- Marvell Technology (MRVL): A prime beneficiary of surging custom AI chip demand. In its fiscal first quarter of 2027 (ended May 2), Marvell posted record revenue of $2.4 billion, up 28% year over year, with adjusted EPS of $0.80, up 29%. Its dual-ecosystem strategy provides flexibility as the market evolves.
- Intel (INTC) and AMD (AMD) face challenges in catching up to Nvidia‘s GPU dominance and Marvell‘s custom chip leadership.
- Broadcom (AVGO) competes with Marvell in ASICs but lacks the networking advantage from the Nvidia partnership.
Counter-Scenario and Uncertainties: Risks to Watch
Not all outcomes are bullish. Prolonged geopolitical instability or an earlier-than-expected peak in AI infrastructure investment could derail growth. If competitors achieve technological breakthroughs, Nvidia‘s moat could narrow. For Marvell, maintaining UALink support while deepening ties with Nvidia creates a delicate balancing act. The cyclical nature of the semiconductor industry also poses inherent risks.
Next Indicators to Monitor: Earnings and Investment Flows
Investors should track quarterly earnings trends for Nvidia and Marvell, particularly data center revenue growth. Any signs of hyperscaler capital expenditure cuts or delays from Amazon, Alphabet, or Microsoft would be a red flag. For Marvell, custom AI chip order backlogs and the expansion of its partnership with Nvidia are key metrics.
