Investors and traders are in no mood for major risk-taking Monday morning as the next Federal Reserve meeting approaches.
U.S. stock futures were modestly higher ahead of the opening bell.
Investors are treading cautiously as they wait to see whether the Federal Reserve will begin cutting back on its massive stimulus program -- which has supported stock markets around the world -- as economic data continue to improve.
"[A] growing minority now believe that the Federal Reserve could start to taper at this week's meeting," said Kathleen Brooks, a research director at Forex.com. "Only a few weeks ago this was virtually unheard of, with most traders and investors looking at late Q1-Q2 2014 for the Fed to start tapering."
The Fed has been pumping $85 billion per month into the financial system since September 2012. It will announce any policy changes after it wraps up its two-day meeting Wednesday afternoon.
