NEW YORK, May 13 (Reuters) - U.S. stocks were little changedon Monday as investors stepped back following last week's newhighs, but stronger-than-expected retail sales data limiteddeclined.
The S&P 500 has jumped more than 14 percent so far thisyear, a rally that has repeatedly taken it to record intradayand closing highs without sustained declines. While thelong-term trend is still viewed as positive, many analysts saidthe momentum could wane in the absence of positive catalysts.

There is a debate playing out in the market over whetherpositive economic data can help the market rise further, orwhether it will spell the end of the Federal Reserve's monetarystimulus, which could derail the rally, said Joseph Tanious,global market strategist at J.P. Morgan Funds.
"You're seeing a little bit of back and forth, you're notseeing a great deal of conviction. You add on top of that thefact that we've had this rally year-to-date and investors are abit hesitant to continue putting more and more money into themarket because everyone's waiting for that pullback, if and whenit will ever come."
