NEW YORK (AP) - U.S. stock futures are rising one day after a broad sell-off left the S&P 500 index lower for the year.
 
Investors will receive reports Wednesday on June factory orders and a reading of growth in the service sector of the economy. Concerns about the economy have sent stocks lower recently.
 
MasterCard, Clorox and ZipCar are among the companies that are expected to release quarterly earnings results by the end of the day.
