The data add to recent evidence, such as Tuesday's disappointing retail sales report for April, that there's little pressure on the Federal Reserve to raise interest rates in the immediate future.
"Despite an even tightening labour market, inflation is totally under control, complicating the Fed's decision-making," Joel Naroff, chief economist at Naroff Economic Advisers in Holland, Pennsylvania, told Reuters. "The Fed must keep its finger on the trigger, even if it doesn't have to pull it just yet."
Indeed, "we find support for our expectations that the Fed will not raise rates until Q4 2015," Jason Schenker, chief economist and president of Prestige Economics in Austin, Texas, wrote in a research note, according to Bloomberg.
Shares of Shake Shack initially jumped 6.5 per cent after the company unexpectedly reported a quarterly profit and upgraded its full-year revenue forecast. The stock recently traded up 0.5 per cent.
Shares of Kohl's sank, last trading 12 per cent lower, after the department store posted weaker-than-expected sales for the quarter. It followed disappointing sales from rivals Macy's and JC Penney, and underpinned concern about the pace of US consumer spending.
"Weather, port issues, and weak consumer spending overall is the department store theme in 1Q-despite a plan to recover traffic, it does not appear that KSS escaped the trend," Evercore ISI analyst Matt McGinley wrote in a note, according to Reuters.
In Europe, the Stoxx 600 Index finished the session with a 0.6 per cent increase from the previous close. The UK's FTSE 100 Index rose 0.3 per cent, France's CAC 40 Index added 1.4 per cent, while Germany's DAX rallied 1.8 per cent.
