U.S. equity benchmarks held near their closing levels through 18:00 EDT. Thin after-hours trading did not extend Friday’s technology-led selloff.

Small caps carried the heavier burden. The Russell 2000 fell 1.4% to 2,972.37 as higher Treasury yields tightened financial conditions.

Marvell fell 10.3% after its outlook failed to clear elevated expectations. Nvidia dropped 4.6%. Intel lost 2.8% as investors reduced chip exposure.
PayPal declined 12.7% after a takeover pursuit reportedly ended. Gap gained almost 13%, and Workday rose 5.8% following stronger operating updates Reuters.
Breadth confirmed the defensive tone. Decliners led advancers by 1.77-to-1 on the NYSE. Nasdaq decliners outnumbered gainers 3,272 to 1,494.
U.S. exchange volume reached 15.68 billion shares. That was close to the 20-day average of 15.8 billion, leaving little evidence of panic selling.
