Dow Futures Tumble as UnitedHealth Earnings Miss. S&P 500, Nasdaq Rising.

Stock futures were diverging sharply as Dow futures tumbled while the S&P 500 and Nasdaq 100 rose in premarket trading Thursday as investors weighed up fresh earnings and signs that trade talks between the U.S. and Japan got off to a good start.

Futures tracking the Dow Jones Industrial Average slumped 612 points, or 1.5%, after UnitedHealth–one of the gauge’s 30 components–posted weaker-than-expected earnings and cut its full-year outlook. S&P 500 futures were up 0.5%, and contracts tied to the Nasdaq 100 climbed 0.8%.

The blue-chip indexes had tumbled Wednesday after chip maker Nvidia said it would now need a license to export some of its processors to China, stoking worries about trade tensions between Washington and Beijing.
