U.S. stock futures on Tuesday pointed to a rise at the open, as investors waited for comments from Federal Reserve chief Janet Yellen and stayed on edge for Brexit-related developments.
S&P 500 futures advanced by 10.80 points, or 0.5%, to 2,085, while Dow Jones Industrial Average futures moved up by 72 points, or 0.4%, to 17,784. Nasdaq-100 futures tacked on 23.50 points, or 0.5%, to 4,413.50.
The gains come after the S&P 500 closed 0.6% higher on Monday, and the Dow added 0.7%, or 129.71 points. The stock market was helped by polls showing support swinging back toward the U.K. remaining a member of the European Union, ahead of a referendum on Brexit set for Thursday.
Yellen is due to speak at 10 a.m. Eastern Time, delivering her semi-annual testimony before the Senate Banking Committee. Some analysts have played down the Fed chief's appearance before U.S. lawmakers. It "has to be the most pointless speech from a Fed chairman in recent memory," said Chris Weston, an IG market analyst based in Australia. "The markets have a myopic focus on one thing: the U.K. referendum vote."
European stocks advanced moderately after soaring Monday as Brexit fears abated, while Asian markets closed mostly higher.
July West Texas Intermediate crude traded lower as market players turned their attention back to oversupply worries. The July contract expires at Tuesday's settlement, and August will become the front month for WTI. Gold futures and the ICE U.S. Dollar Index both lost ground.
