Markets shook off a fresh set of data that pointed to a slowdown in the U.S. economic recovery. U.S. manufacturing activity held at the year's lows in April. Markit revised its index of U.S. manufacturing conditions to 54.1 in April from 55.7 in March as industrial companies continued to hurt from a stronger dollar.

In a separate report, manufacturing activity held at 51.5 in April, its lowest level since May 2013, according to the Institute for Supply Management index. Economists had expected a reading of 52.

"This was a weak report and the absence of any bounce is a clear indication that the U.S. economic recovery has remained mired in a soft patch," said Millan Mulraine, deputy head of U.S. strategy at TD Securities. "We believe that the case for a mid-year (June or July) hike by the [Federal Reserve] is becoming compromised."

Consumer sentiment improved in April with a reading of 95.9, up from 93 in March, according to a University of Michigan survey. The improvement was as expected.

Non-farm payrolls for April will dominate the economic calendar in the week ahead. Economists expect 225,000 jobs to have been added over the month, far better than 126,000 added in March. The unemployment situation report will be out before the bell on Friday.
