Relax, take a deep breath and wait for the upside. It is at the bottom. Please learn the lesson to always implement stop loss orders to protect your investments from going down so much.
Actually no. Look at it this way there is really no benefit to you selling this, meaning you rode it all the way down. Just put it away and hope there is a turn around. All it takes is one positive report. You can recover some of your losses,if not make it all back. It is hard but I've been in this position before.
The 10q shows that YoY they almost doubled R&D. Had they limited R&D spending to just a 50% increase they would have beat with +.03 instead of a loss of -.03.
Ask yourself, why would they willingly sustain a loss from such a profligate spending increase? Do they have some kind of an "atomic bomb" application under development (legalized gambling) or are they just another corporate management with an active disdain for the interests of their shareholders?
The rules of the equity game are based on complete dishonesty to the contention that corporations work in the best interest of the owners, the shareholders, and Zynga management appears to be just another glaring example.
Should you hold? Simple, write to them and ask how long they intend to continue to double R&D spending without result or definitive explanation.
