U.S. stock-index futures were mixed early Thursday, with Nasdaq 100 futures edging lower while Dow and S&P 500 futures were little changed as investors assessed the latest round of technology earnings. In extended trading, Cisco Systems fell 4% after its sales outlook tied to the AI data center boom missed expectations. Coherent dropped 3% and Cerebras Systems slid 16% after disappointing quarterly results. Attention also turned to producer inflation data due Thursday, after Wednesday’s consumer price index report showed relatively stable core inflation, a backdrop that reduced pressure on the Federal Reserve to raise interest rates. In Wednesday’s regular session, the S&P 500 rose 0.26%, the Nasdaq Composite added 0.54%, and the Dow slipped 0.04%.
