US markets waver before midterm results as investors weigh political uncertainty

US markets opened mixed Tuesday ahead of midterm election results, with the tech-heavy Nasdaq rising 0.39% while the Dow Jones fell 0.38%, reflecting investor caution over political uncertainty. Apple and Palantir shares dropped after earnings reports, despite Apple posting record quarterly revenue of $114.5 billion, as concerns persist over AI investment profitability and slowing growth forecasts. The elections could impact AI-related investments, particularly data center approvals in competitive states, while oil prices fell slightly and bond yields rose to 4.96% ahead of Friday's employment data.
