NEW YORK, Dec 17 (Reuters) - U.S. stocks edged lower on Tuesday as the Federal Reserve prepared to begin its last policy-setting meeting of the year.
Although many in the market expect the Fed to begin to wind down its market-friendly $85 billion a month in asset purchases in March, some are betting on an earlier tapering of stimulus after a recent string of better-than-expected economic data.
U.S. consumer prices were flat in November, but a bounce back in the annual inflation rate from a four-year low will probably give the Fed cover to start the taper. Separate data showed the U.S. current account deficit was the smallest in four years in the third quarter as exports increased and more income was earned abroad.
The Fed has said its current policy is data-dependant, and some market participants believe the U.S. central bank will upgrade its estimates for economic activity after a two-day meeting that is set to begin later on Tuesday.
"The Fed meeting begins today so I don't expect the market to do much after yesterday's strong performance," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.
"The news remains consistent with an economy that continues to gain traction and the market has discounted a Fed move."
The Dow Jones industrial average rose 8.28 points or 0.05 percent, to 15,892.85, the S&P 500 lost 3.49 points or 0.2 percent, to 1,783.05 and the Nasdaq Composite dropped 6.391 points or 0.16 percent, to 4,023.126.
