Wall Street ended flat as the latest deal news offset losses following soft data on the housing market and services sector. The market may also be hitting resistance with the Dow Jones industrial average sitting just below 17,000 and the S&P 500 near 2,000.
"Technically, we are battling round numbers that I think give investors reason to pause," said Todd Salamone, senior vice president of Research, Schaeffer's Investment Research in Cincinnati.
