Stock Market 3 February 2026
U.S. markets reopened after the Juneteenth holiday with mixed performance across sectors. Coherent closed just below its 52-week high, driven not only by a $50 million CHIPS letter but also by signals about U.S. indium phosphide capacity amid China’s stricter indium controls, highlighting the importance of Coherent’s Texas wafer operations. The S&P 500 and Nasdaq fell, with the Nasdaq down over 1% as losses in Alphabet, Meta, Amazon, and Microsoft weighed on tech stocks. Alphabet dropped 5.5%-6%, contributing to the tech sector’s weakness, while the Dow gained 0.28% on strength from Caterpillar and Visa. UiPath traded down 1.2% ahead of its annual meeting, with investors focused on recurring-contract growth and the company’s remaining buyback capacity. Lumentum rose 6.1%, tracking a rally in Coherent, which counts Nvidia as a backer. Applied Optoelectronics gained 7.8% after a China unit doubled its credit line, signaling a manufacturing ramp. Palantir slid over 6% to a new 52-week low as software stocks slumped, with investors questioning AI spending and valuations. Ford was flat as Canadian contract talks began, and Ondas slipped 1.9% despite announcing over $40 million in defense orders. SoFi fell 3.6% as traders weighed insider buying and its stablecoin push. Rocket Lab dropped 7.2% despite joining the Nasdaq-100, with sector weakness and SpaceX performance cited. CoreWeave and Nebius, also new Nasdaq-100 members, reversed earlier gains. The VanEck Semiconductor ETF saw $6.93 billion in net inflows, making up a significant portion of technology sector fund flows.
