Most US stocks rise as oil prices ease, but slumping AI stars weigh on Wall Street

US stocks opened mixed as oil prices eased, with the S&P 500 down 0.1% after a nine-day win streak, and the Dow rose about 1.4% to lead gains of roughly 720 points as of 10:15 a.m. Eastern. The Nasdaq fell 0.7% and Brent dropped 2.9% to 94.96 per barrel, which eases inflation pressures.

Toro rose 1.4% after lifting full-year revenue and profit forecasts, while Broadcom tumbled 14.5% despite beating on profit and revenue, as AI semiconductor demand remains volatile. Other AI winners such as Marvell, Micron and CrowdStrike also traded lower, underscoring a pause in the sector after a rapid rally.
