Energy shares weighed, with declines in Exxon and Chevron keeping the Dow industrials flat while the S&P 500 energy sector was down 1 percent. U.S. crude and Brent fell ahead of an OPEC meeting this week.

"This week's OPEC meeting will provide investors with a better idea of oil output," Rob Williams, deputy editor of MoneyNews.com, said on "The Steve Malzberg Show" on Newsmax.TV. "OPEC has been producing about 31 million barrels of oil a day, and that may be cut by 1 million barrels to prevent prices from slumping even more."

Helping bullish sentiment was expectation central banks will continue to boost equities. Following last week's surprise rate cut, China's leadership and central bank are ready to cut interest rates again and to loosen lending restrictions.

"You tend not to cut rates once, it doesn't happen in a vacuum. This could be the first in a series. The question is, how much they are going to have to do before it works," said Brian Battle, director of trading at Performance Trust Capital Partners in Chicago.

He said the market could continue to drift upwards.

"There's going to be an impulse to buy here at the end of the quarter and the year."
