U.S. stock index futures were marginally higher Tuesday morning, as economic fears remain in investors' mindsets.
At around 02:30 a.m. ET, Dow futures rose 44 points, indicating a positive open of more than 85 points. Futures on the S&P and Nasdaq were slightly higher too.
Wall Street closed Monday with small gains. News that the special counsel Robert Mueller did not find evidence that President Donald Trump colluded with Russia in the 2016 presidential race boosted stocks. But overall concerns regarding the global economy capped that move.
