Nvidia stock has trailed the S&P 500 for much of 2026, and a Seeking Alpha analysis argues three factors may extend the underperformance: hyperscaler custom chip programs, AI spending sustainability concerns, and valuation normalization. Nvidia's trailing P/E ratio has fallen to 30.69x, well below its five-year median of 60.51x, per GuruFocus data from June 10. Insider selling totaled $388 million over the prior three months with no reported purchases.
Background
Nvidia's stock has trailed the S&P 500 during much of 2026, a notable reversal for the dominant AI chip supplier. A June 2026 Seeking Alpha opinion piece outlines three reasons the underperformance may persist.
Valuation compression
Nvidia's trailing price-to-earnings ratio has fallen to 30.69x - significantly below its five-year median of 60.51x - per GuruFocus data from June 10, 2026. The stock closed at $200.42 that day, roughly 6% below its level a month prior, and its forward P/E of approximately 24x still implies strong expected growth. GuruFocus labels the stock a potential "value trap" despite a top-tier GF Score of 96/100, pointing to significant insider selling of $388.3 million over the prior three months with no reported insider purchases.
Hyperscaler custom chip competition
A core concern is accelerating in-house AI silicon development by the largest cloud providers. Amazon's Trainium2 chip was described in the company's Q4 2025 earnings call as "fully subscribed with 1.4 million chips landed" - and Anthropic uses it to train its Claude AI models. Amazon CEO Andy Jassy said in that call: "A significant impediment today is the cost of AI chips. Customers are starving for better price performance." Alphabet and Microsoft have similarly expanded their custom silicon programs, diverting workloads that would previously have run almost exclusively on Nvidia hardware.
AI spending sustainability
Investors are also weighing whether hyperscaler AI capex commitments are durable. Amazon alone has indicated capital expenditure plans of roughly $200 billion, against a trailing-12-month free cash flow of $11.2 billion at the time - a ratio that implies deep negative free cash flow if sustained. If AI infrastructure spending decelerates, Nvidia's top-line growth trajectory would be directly exposed.
Context
Per GuruFocus's GF Value methodology, Nvidia appears undervalued at $200.42 versus an intrinsic estimate of $339.82 - a 41% discount. However, the same system flags elevated risk of a value trap, a label that reflects the combination of compressed multiples and meaningful insider selling. The primary source for this story is a Seeking Alpha subscriber analysis (opinion), corroborated by GuruFocus market data and Motley Fool reporting from early 2026 that documented the same three structural headwinds.
Scoring Rationale #
A single Seeking Alpha opinion piece arguing three reasons Nvidia stock may continue trailing the S&P 500; the underlying market dynamics are real and corroborated by GuruFocus data and Motley Fool reporting, but this is financial market analysis rather than AI/DS/ML news. Nvidia's hardware dominance makes its valuation and competitive dynamics peripherally relevant to AI practitioners, but the story does not report a technology development, model release, or infrastructure shift - it is investor opinion on an ongoing trend.
