Chip worries split the market
Qualcomm fell 9% even after a slight fiscal fourth-quarter earnings beat, as smartphone chip sales missed Wall Street estimates. Handset-division revenue dropped 26% to $5.14B, dragging the chip segment down 8% to $9.02B.
Marvell Technology dropped 3.4%, with Nvidia off 0.8% and Intel down 2%, as chip stocks extended Wednesday's losses. CoreWeave and Nebius fell 3% each and Dell lost 2.9% after UBS strategists warned data-center pauses put ~30% of expected 2028 additions at risk.
Amazon, Meta and Alphabet rose more than 1% as a slower AI build-out was seen helping big tech, while SpaceX and Tesla fell more than 1% each.

EPAM Systems gained 13.6% after adjusted EPS of $3.51 beat the $3.40 consensus and revenue of $1.426B edged past estimates, with the IT-services firm raising its full-year outlook and adding $1.5B to its buyback.
Zillow fell 16.6% after missing on key third-quarter metrics, with adjusted earnings of 55 cents against the 59-cent consensus, revenue of $724M versus the $754M expected, and a cut to its full-year sales outlook.
Dutch Bros slid 13.7% after full-year revenue guidance of $2.10B landed below the $2.13B expected, overshadowing a slim third-quarter beat.
Snap tumbled 9.8% after revenue of $1.72B came in just below the $1.73B estimate and daily active users of 495M missed the 499M expected, with ad revenue growth slowing to 4% year over year.
