Stocks Whipsawed as Fed Doubts Grow, AI Valuation Fears Intensify — Evening Brief – 11.14.25
U.S. equities had a wild ride over the past two days as investors reassessed the likelihood of another Federal Reserve rate cut in December while simultaneously confronting growing concerns about the sustainability of AI-driven valuations. What began as a recalibration in expectations has now evolved into a broader risk-off move, driven by both policy uncertainty and a deeper examination of the leverage behind the AI infrastructure boom.
The AI trade—responsible for powering the market’s three-year rally—is facing its most difficult test yet. Investors are increasingly focused on the massive borrowing required to build data centers, energy capacity, and semiconductor supply chains, raising questions about whether earnings can keep pace with the capital deployed. Lofty valuations leave little room for disappointment, and next week’s Nvidia earnings are widely viewed as a make-or-break moment for sentiment around the entire AI complex.
At the same time, the bond market is flashing warning signs. Volatility has risen as Fed officials push back against expectations for imminent easing. Minneapolis Fed President Neel Kashkari reiterated that he did not support the central bank’s last rate cut and remains unsure about the appropriate stance for December. Cleveland Fed President Beth Hammack said policy must remain “somewhat restrictive,” while Kansas City Fed President Jeffrey Schmid—who dissented at the last meeting—warned that further cuts could keep inflation stuck near 3%, above target, without improving labor-market conditions.
The shift in tone has been swift and decisive. Market odds of a December rate cut have fallen to below 50%, from 63% earlier this week and more than 95% a month ago, marking one of the sharpest repricings of Fed expectations this year.
The nervousness is evident across markets. Tech stocks—still trading at the richest multiples—have been hit hardest. Each time the outlook skews hawkish, AI-linked megacaps have absorbed outsized losses, revealing how dependent the broader market is on continued momentum in a handful of stocks.
Yet beneath the surface, U.S. equities show surprising resilience. The equal-weighted S&P 500 has held far better than the market-cap-weighted index, suggesting healthier participation outside the AI-heavy megacap cohort. This divergence underscores the growing concentration risk: the broader market is sound, but leadership remains precariously narrow.
A strong Nvidia report could stabilize sentiment—but a miss or cautious outlook could accelerate the unwind in one of the market’s most crowded trades.
