News Summary: Zynga stock down after lower outlook

DECLINE: Zynga's stock traded near its lowest level ever Friday.

WHAT HAPPENED. A day earlier, the online game maker behind "FarmVille" forecast a third-quarter loss amid weak demand for its Web-based games. It's also taking a hefty charge related to its March acquisition of mobile game company OMGPop.

THE ANALYSIS: Baird analyst Colin Sebastian says Zynga's transition from Web-based Facebook games to mobile is "more painful than expected."
