NEW YORK, Dec 10 (Reuters) - Wall St was set to take a breather on Tuesday after the S&P 500 closed at yet another record high and as investors were hesitant to make big bets amid uncertainty over the Federal Reserve's stimulus.
Shares of General Motors Co were down 0.8 percent in volatile trading before the bell after the company named Mary Barra as its next chief executive.
S&P 500 futures fell 6 points and were below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures lost 52 points and Nasdaq 100 futures fell 8.5 points.
The benchmark S&P 500 rose to a new high on Monday even as a number of policymakers suggested the U.S. central bank may be closer than previously thought to trimming its $85 billion a month in bond purchases.
"We are pretty much at the high end of a trading range. The key is that the market is absorbing core Fed speakers singing the same tune that tapering is in the air and there will be some sort of announcement next week at the FOMC meeting. It is taking it pretty well," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.
