Wall Street took a pause after a big rally, with trading steady after slipping on opening, and ahead of US Federal Reserve talks later in the week which will be closely watched for clues on any further rate hikes.
"US stocks are trending lower as decreasing oil prices weigh on energy stocks and investors pause ahead of the US Federal Reserve's monetary policy meeting," analysts Edward Jones said in an investor's note.
Mark Vickery, of Zacks, said the Federal Reserve was the "biggest thing on the docket for the markets this week", even if the expectation was for no further change for the time being.
"No one really expects a new move this time around, considering the tightening global economy adding pressures that would be further amplified by another turn of the screw in the US," he wrote in a note to investors.
