US stocks closed mixed on Thursday after a weak session, with the S&P 500 slipping 0.1% and the Nasdaq falling 0.5%, while the Dow edged 0.1% higher.
Losses were driven by a sharp selloff in technology as investors reassessed AI related valuations amid a heavy slate of earnings.
Microsoft sank 10% after flagging slower cloud growth alongside a surge in AI infrastructure spending, dragging on the broader tech complex and weighing heavily on the Nasdaq.
Software names followed lower as margin concerns resurfaced, reinforcing the pullback across growth stocks.
On the upside, Meta jumped 10.4% after delivering a stronger than expected revenue outlook, while IBM (5.1%) and Caterpillar (3.4%) outperformed after posting earnings that beat forecasts.
Elsewhere, Apple ended 0.7% higher ahead of results after the close, while modest safe haven demand supported Treasuries and commodities diverged, with oil firmer on geopolitical risks and gold retreating from recent highs.
