U.S. stock index futures are signalling a lower open on Wall Street on Wednesday, as a tentative rebound in oil prices fades.
The ADP Employment report, which is seen as a precursor to Friday's important jobs report, showed January payrolls increased by 213,000, below estimates of 225,000.
"Bottom line, job gains slowed, due in part to the energy sector but at more than 200,000, the monthly job gains still remain good, not great," Peter Boockvar, chief market analyst at The Lindsey Group, said in a note.
"Friday's payroll estimate for the private sector is 228,000 with an unchanged unemployment rate of 5.6 percent," he said. "But, with monthly job gains continuing at plus-200,000, the unemployment rate could be at the Fed's non-accelerating inflation rate of unemployment by the time they walk into their April meeting. If they aren't raising rates by June, they'll have some explaining to do, especially if commodity prices have stopped going down."
