U.S. stocks split on Monday as investors grew more cautious about the artificial intelligence trade, sending tech-heavy indexes lower while blue-chip stocks edged up.

The S&P 500 fell 0.56% and the Nasdaq Composite dropped 1.12%, with AI-linked stocks bearing the brunt of the selling. The Dow Jones Industrial Average bucked the trend, rising 0.22%, reflecting a modest rotation away from high-growth tech names toward more traditional sectors.

Why Tech Sold Off

The divergence between the Dow and the Nasdaq tells the clearest story: investors are questioning whether AI-driven valuations can hold. The Nasdaq is heavily weighted toward technology companies that have rallied sharply on AI optimism over the past year. When confidence in that growth narrative softens even slightly, those stocks tend to fall faster and further than the broader market.

Concerns about the AI boom typically center on a few pressure points: whether revenue from AI products is growing fast enough to justify elevated stock prices, whether the massive capital spending on data centers and chips will pay off on a reasonable timeline, and whether early enthusiasm has pushed valuations too far ahead of actual earnings.

What to Watch

A single session's move doesn't signal a trend reversal, but back-to-back sessions of tech underperformance would be worth watching closely. Upcoming earnings from major AI-exposed companies will be the real test — if revenue and profit guidance disappoint, the pressure on Nasdaq-listed names could deepen.

The Dow's resilience suggests money is moving toward more defensive or value-oriented stocks rather than leaving equities altogether. That rotation dynamic has played out before during periods of tech uncertainty and can persist for weeks if sentiment stays cautious.

S&P 500: -0.56%
Nasdaq Composite: -1.12%
Dow Jones Industrial Average: +0.22%

For now, the session is a reminder that the AI trade is not a one-way bet. Markets are starting to demand proof — in the form of earnings and user growth — that the technology boom is translating into real financial results.
