U.S. stocks opened mixed on Tuesday as traders awaited Big Tech earnings.

The broad market index gained 0.2%, while the Nasdaq Composite climbed 0.6%. The Dow Jones Industrial Average struggled, losing 402 points, or 0.8%, due largely to a 16% drop in UnitedHealth.

UnitedHealth forecast a decline in 2026 revenue, the first annual contraction in more than three decades, as the company works to rebuild confidence with investors after a stunning fall last year.
