US stocks: Nasdaq, S&P end lower in volatile session as tech stocks retreat

The market exhibited classic sector rotation dynamics as technology stocks retreated on valuation concerns and mounting questions around artificial intelligence capital expenditure sustainability. This pullback dragged the Nasdaq lower, signaling investor reassessment of mega-cap tech multiples in an environment where near-term AI monetization remains uncertain.

Beneficiaries of the rotation included airlines and travel stocks, which rallied on declining crude prices that improve operating margins and consumer discretionary demand. Simultaneously, homebuilders surged, suggesting reduced borrowing cost sensitivity expectations ahead of upcoming inflation data. The Dow's outperformance reflects strength in cyclical and industrials components outside the technology-heavy indices.

The divergence between index performances—Nasdaq down, Dow up, S&P 500 declining—reveals a market in tactical flux rather than directional conviction. Investors appear to be hedging technology exposure while positioning for potential Federal Reserve policy shifts based on inflation trajectory.

Sector implication: This session illustrates the fragility of the tech-driven rally, with spillover effects limiting broad market gains despite strength in defensive and economically-sensitive pockets. Watch for confirmation in earnings and macro data.
