Wall Street set to open little changed amid earnings

Wall Street was set to open little changed on Tuesday as investors digest earnings reports from a slew of consumer products companies, including Kellogg, Coach and CVS Health. Among other companies scheduled to release results are Dow component Walt Disney, Devon Energy and Genworth Financial. Wall Street ended lower on Monday as tumbling oil prices dragged energy shares to a three-year low and factory data from China raised concerns about the world's second-biggest economy.
