Chip stocks hit dot-com bubble overbought levels on AI demand

Semiconductor equities have experienced a parabolic rally, with memory chip makers climbing 30 percent in a single week on supercycle narratives. Goldman Sachs data reveals that according to the SOX/CPI ratio (semiconductors versus inflationThe rate at which prices rise across an economy.), chip stocks are now more overbought than at the peak of the March 2000 dot-com bubble. Broadcom has benefited from Goldman's reset of its stock forecast, and CoreWeave's CEO told Yahoo Finance that Nvidia must expand AI capacity or risk losing customers to AMD. Nvidia's deal with CoreWeaver and involvement with infrastructure names like Iren and Corning underscores the circular investment theme: Nvidia sells GPUs to infrastructure companies, which then build data centers that require even more chips.

Memory stocks including Micron (MU), SanDisk (SNDK), and Broadcom (AVGO) have all appreciated sharply. Reports indicate AI memory demand remains in early stages with supply shortages expected to stretch for years. Margin projections for 2027 have been lifted by higher pricing power. Yet this enthusiasm faces headwinds from elevated valuations and questions about the durability of the AI capex cycle. Nvidia's recent stock performance has lagged despite analyst enthusiasm, which some interpret as a sign that sentiment is getting ahead of fundamentals.

Winners include data center infrastructure plays (CoreWeave, Northern Data via Rumble's acquisition), semiconductor OEMs, and chip equipment makers. Losers could include any tech name viewed as overpriced without clear AI positioning. Premium SaaS and healthcare tech names have been repriced hard YTD, suggesting sector rotation is already underway.

Bears point to the parallel with 2000, when Nasdaq valuations collapsed despite strong fundamentals. Circular investment risks persist: if capex proves unsustainable or returns on AI infrastructure investments disappoint, the supercycle narrative will crack. Recent analyst commentary obsessing over 'when this will collapse' rather than where the rally goes next suggests crowded positioning and near-term reversal risk.
