NEW YORK (TheStreet) -- U.S. stock futures moved solidly higher on Wednesday, looking to end a poor third quarter on a positive note. This quarter has been the worst for equities in four years. 

S&P 500 futures were up 1.2%, Dow Jones Industrial Average futures climbed 1.1%, and Nasdaq futures added 1.3%.

The U.S. economy added 200,000 private sector jobs in September, above expectations for an increase of 190,000. However, August's job gains were revised down to 186,000 from 190,000, according to the ADP jobs report. The official jobs report from the Labor Department will be released on Friday. 

Major benchmark indexes were on track for quarterly losses of around 9% after facing a range of worries over the past three months. Prime among them, China's devaluation of the yuan and further signs of a slowdown in the world's second-largest economy that rocked markets since August. 

European markets moved higher even after fresh data showed the eurozone slipping into deflationary territory again. Inflation in September fell 0.1% across the eurozone despite the European Central Bank's stimulus program.  

Asian markets closed in the green after consumer sentiment in China improved to its highest level since 2014. The Westpac MNI China Consumer Sentiment Indicator rose to 118.2 in September, its best reading since May last year.

Sales in the U.S. rose 2%, or 6% excluding gas and foreign exchange, over the fourth quarter. Domestic strength offset weakness in Canada and other international markets. 

Ralph Lauren(RL) - Get Report climbed 6% in premarket trading after its namesake CEO and founder announced he was stepping down as chief executive. Gap's(GPS) - Get Report  president of Old Navy, Stefan Larsson, will assume the role of CEO.
