I never heard of Zynga until it appeared on Prooftrader. They just reported earnings (losses), guided lower and have heavy insider selling. The key here is that they are in the consumer sector and except for Apple products, the consumer is holding back on spending money. Many consumer stocks (AMZN, BBY) are below their 200 day moving average and should be considered for short selling. This IPO hasn't even been around for 200 days. Another reason to avoid IPOs.
