Wall Street fell overnight after stronger-than-expected US private jobs data raised concern the Federal Reserve might begin tapering its bond-buying program sooner than anticipated.
An ADP report showed private employers added 215,000 new jobs to their payrolls in November, the largest increase in a year and comfortably exceeding economists' expectations. Meanwhile, October's rise was revised to 184,000, up from 130,000.
"The market is on alert for any signs of Fed tapering and these ADP numbers will raise those concerns for investors," Stewart Richardson, chief investment officer at RMG Wealth Management in London, told Bloomberg News.
Indeed, those data also boosted expectations for Friday's Labor Department, which was expected to show an increase of 180,000 in nonfarm payrolls, according to a Reuters poll of economists.
"If the ADP does prove to be a good guide, a 200,000 plus gain [in nonfarm payrolls] might just be enough to persuade the Fed to begin its QE taper later this month," Paul Ashworth, chief US economist at Capital Economics in Toronto, told Reuters.
