NEW YORK, May 6 (Reuters) - U.S. stocks were flat on Monday as investors paused following a sharp rally that took major averages to record highs last week.
Equities have been strong so far this year, with the S&P 500 up more than 13 percent in 2013 on the back of strong corporate earnings and accommodating monetary policies that have kept interest rates low.
But with those factors largely priced into the market, many investors are looking for the next catalyst to take shares higher. Many analysts expect a correction, which markets have largely avoided this year as traders use weakness as an opportunity to add to positions.
"Everyone is settling in for the moment. We had a nice week last week and there are no real catalysts to move us significantly one way or the other today," said Mark Martiak, senior wealth strategist at Premier/First Allied Securities in New York.
Weak economic data has recently underlined concerns over the global growth outlook, though Friday's payroll report was stronger than expected and fueled the gains that took the indexes to record levels.

The Dow Jones industrial average was down 30.41 points, or 0.20 percent, at 14,943.55. The Standard & Poor's 500 Index was down 0.07 points, or 0.00 percent, at 1,614.35. The Nasdaq Composite Index was up 4.74 points, or 0.14 percent, at 3,383.37.
BMC Software Inc agreed to be acquired by a private equity group led by Bain Capital and Golden Gate Capital Corp for about $6.9 billion. Shares dipped 0.3 percent to $45.27.
Overseas, European shares dipped 0.2 percent as investors took profits following a rally in the previous week. Volumes were light as London markets closed for a holiday.
