Semiconductor stocks hit record highs in mid-June 2026. JPMorgan is now asking a pointed question: what happens when everyone tries to exit the same trade at once?
In a note dated June 18, the bank’s strategists warned that volatility spikes in chip stocks like Nvidia and AMD could breach portfolio Value-at-Risk limits at institutional funds. When that happens, the selling isn’t optional. It’s mechanical, automatic, and indifferent to whether the underlying business is thriving.
The crowding problem
JPMorgan has been sounding this alarm for nearly a year now. Back in July 2025, the firm published a note describing AI-linked momentum stocks, including Nvidia (NVDA), Palantir (PLTR), and Coinbase (COIN), as reaching the most extreme crowding levels in 30 years.
What’s notable is that JPMorgan’s concern isn’t really about the AI chip business itself. The firm’s recent reports don’t point to falling demand for AI chips or deteriorating fundamentals. The risk they’re flagging is structural: it’s about how markets behave when volatility rises in stocks that institutions have crowded into with historically unusual intensity.
