Don't be that jealous of me... I pretty much am in the same boat as you.. I was all in much much higher than 5.5... and buying on margin isn't something to be proud of, this could turn ugly for me quite easily.
I don't know about the positive news so much.. Much of it wasn't news, it was old info... the online gambling purchase was legit tho, but it didn't do anything to the stock. Fairly low volume day for a short trading day tho... Plus I presume before a holiday, people probably sell?
Pincus isn't in this group that's got expiring lock-ups... so he doesn't care.. He's a narcissistic, ego driven sociopath... he doesn't care about anyone but himself and maybe a couple of his friends that could help him later... It is no surprise Zynga rarely puts out any news...
