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

Tech sector experienced notable weakness as the Nasdaq retreated amid mounting concerns about valuation compression and unsustainable AI capital expenditure trajectories. Semiconductor names like MU faced headwinds typical of hardware-adjacent plays during periods of multiple contraction, reflecting broader investor skepticism about near-term returns on massive compute infrastructure outlays.

Divergence within equities proved pronounced: while large-cap tech indices declined, energy-sensitive beneficiaries emerged as crude prices softened. Airlines and travel operators capitalized on lower fuel cost environments, with carriers and leisure-adjacent equities outperforming. This sector rotation underscores tactical allocation shifts toward cyclical inflation hedges amid macro uncertainty.

The Dow's resilience contrasts sharply with Nasdaq weakness, signaling a rotation toward value and industrials over growth. Real estate plays, particularly homebuilders, surged—likely anticipating potential Fed accommodation if inflation data validates dovish repricing. This combination suggests market participants are hedging multiple scenarios around monetary policy transmission.

Sector implication: The sell-off reflects not macro crisis but rather a repricing of growth multiples and AI capex ROI expectations. Inflation data becomes the critical inflection point for Fed expectations, with downstream implications for both bond yields and equity duration risk across technology and financials.
