Investors were in wait-and-see mode ahead of the kickoff to the fourth-quarter earnings season later in the week. Average earnings for the S&P 500 in the fourth quarter are expected to increase 4.4% from the same period a year earlier. Earnings growth would mark the second straight quarter of gains after the third quarter broke an earnings recession that lasted for four consecutive quarters.

"We believe investors are pricing in a beat for fourth-quarter earnings," said Lindsey Bell, investment strategist at S&P Capital IQ. "EPS growth hasn't fallen short of expectations since first quarter 2009 and the past two quarters had solid beat rates of 4.9% and 3.5%, respectively. As long as investors don't anticipate a greater-than-average beat, fourth-quarter earnings shouldn't rock the market.
