On CAPS, 86% of the 192 members who have rated Zynga in believe the stock will underperform the S&P 500 going forward. These bears include webhappy and AWinvestments.  

Earlier this week, webhappy cautioned our community about buying into Zynga: "No moat to prevent users from defecting to rivals in the future. Facebook really has all the power here. I also think users have peaked as people realize how mindless their games are."

In fact, Zynga currently sports a rather lofty forward P/E of 47. That represents a clear premium to other video game developers like Activision (12), Electronic Arts (17), and Take-Two Interactive (Nasdaq: TTWO) (5).

CAPS member AWinvestments elaborates on the bear case:

Zynga has a few hits, such as Farmville and Cityville. However, a few hits doesn't assure long-term success in the brutal business of gaming. ... So, it is a much better and safer idea to go with a company that's been around for decades, making some of the biggest gaming franchises, such as John Madden Football by Electronic Arts. As for Zynga, there's no evidence yet that this horse will ever run and by the time the IPO holders can trade this over-hyped stock, an investor in the public markets could be left holding a big bag of nothing but hope. Pass.
