US stock futures mixed as midterm elections and earnings weigh

US stock futures were mixed Tuesday as Americans voted in midterm elections, with Apple and Palantir falling after earnings disappointed investors. Dow Jones futures dropped about 290 points, or 0.6%, while S&P 500 contracts slipped 0.08% and Nasdaq 100 futures hovered near flat. The cautious mood followed Monday's session, when the Nasdaq Composite lost 1.07% and the S&P 500 fell 0.51%. Apple reported fiscal fourth-quarter revenue of $114.5 billion, up 12%, but guided December-quarter gross margins to 45%–46%, below September's 47.9%, due to rising memory chip costs. Palantir also declined despite 96% revenue growth to $2.31 billion, as total contract value rose only 6% year-over-year. Oil prices rebounded as US-Iran tensions escalated, with Brent up 1.76% to $106.61 per barrel after US strikes near the Strait of Hormuz. Investors awaited September job openings data, expected at about 7.1 million, which could influence Federal Reserve rate expectations. AMD earnings due after the close will test AI stock sentiment.
