A downgrade to Neutral from Piper's Michael Olson has made Zynga among the day's big tech losers. Olson predicts Zynga's bookings decline will continue "at a steeper pace" into 2013. He also claims a survey of over 7,700 teens confirms "social gaming is as unpopular among teens as we have ever seen" - that's not exactly good news for Facebook (FB -2.3% - previous) either. Glu Mobile's pre-announcement might also be affecting Zynga's shares.
