Trading could be quiet Tuesday, with investors waiting for the resolution of fiscal cliff negotiations in Washington and the outcome of the U.S. Federal Reserve two-day meeting.
Investors have been reluctant to place big bets before lawmakers reach a compromise on tax increases and spending cuts set to kick in automatically on Jan. 1. Without a deal, the U.S. economy could fall back into a recession.
U.S. stock futures were up between 0.2% and 0.3%.
"As has been the case since the elections, the main issue affecting U.S. markets remains the fiscal cliff," said Russ Koesterich, global chief investment strategist at BlackRock. "Although it is impossible to know exactly what is going on behind closed doors, on the surface, the two parties still seem quite far apart on the three main fiscal cliff issues."
Koesterich said the odds of going over the cliff are higher than what the market has priced in so far, which means there is heightened risk for a sell-off. Plus, even if a deal is reached before the end of the year it will likely be only a "small, stopgap sort of agreement" that will still weigh on economic growth.
