U.S. stocks inched higher on Wednesday, pushing the S&P 500 to another intraday record, after data suggested the economy was slowly building momentum after a winter-related pullback earlier in the year.

Eight of 10 S&P 500 sectors were in positive territory, though gains were limited following a recent push to new highs.

U.S. private employers added 191,000 workers in March, slightly below the 195,000 forecast, while gains in the prior month were revised to 178,000 from a previously reported 139,000, signaling that a winter-related impact on job growth earlier this year was easing.

Separately, orders for manufactured goods jumped 1.6 percent in February, the biggest rise since September and above a 1.2 percent estimate. January's orders were revised to show a larger 1.0 percent drop instead of the previously reported 0.7 percent fall.

"We are in positive economic data territory but to continue to make new highs, we are going to have to see improvement, not just good, but great and that is why we are holding tight here," said Art Hogan, chief market strategist at Wunderlich Securities in New York.
