Stock futures moved higher on Wednesday morning after a reading on the labor market showed 154,000 jobs added to private payrolls in the U.S. in September. 

S&P 500 futures were up 0.28%, Dow Jones Industrial Average futures gained 0.27%, and Nasdaq futures were up 0.24%. 

The U.S. economy added 154,000 jobs to private payrolls last month, according to the ADP National Employment Report. The measure came in below consensus of 170,000. The U.S. economy added 177,000 jobs in August. 

ADP's report tends to show a larger increase in the number of jobs added to the U.S. economy than the official report, though it is a good broad indicator of the health of the labor market month to month. The official Labor Department report will be released on Friday morning. 

The U.S. trade deficit was $40.7 billion in August, wider than an anticipated $39 billion deficit. U.S. imports increased 1.2% in August, an 11-month high, while U.S. exports increased 0.8% to a 13-month high.

Stocks tumbled on Tuesday afternoon as gold prices slumped and reports of potential tapering from the European Central Bank surfaced. Reports emerged that the central bank could begin winding down its quantitative easing program earlier than its targeted March 2017 end date. The central bank currently repurchases €80 billion (nearly $90 billion) a month, a program it could pare by €10 billion at a time. ECB media officer Michael Steen tweeted that ECB members had not discussed reducing the rate of bond purchases. 

Gold prices moved slightly higher on Wednesday after hitting their lowest level since the late-June Brexit vote on Tuesday. Spot gold fell 3% on Tuesday, breaching the key support level of $1,300 an ounce and suffering its worst one-day percentage decline since December 2013. Prices had slumped as the U.S. dollar marched to a two-month high.
