U.S. stock index futures were slightly lower Tuesday morning, amid uncertainties over the prospect of a trade deal between the world's two largest economies.
At around 4:30 a.m. ET, Dow futures fell 48 points, indicating a negative open of more than 60 points. Futures on the S&P and Nasdaq were seen lower as well.
Market focus is largely attuned to global trade developments, after the U.S. and China agreed to restart trade talks over the weekend.
