Chief - went ballistic when? If you're referring to the halycon $150+ days in 2007, all I can say is that 2007 was an eon ago in terms of market manipulation. There wasn't anywhere near the level of high-frequency trading, dark pools, and sheer criminal manipulation as today. If you're referring to January 2013 when it rose to $18+, I would argue that was an orchestrated run by American short-sellers with every intention of pummelling it back down to recoup some of the losses they will incur on the shares they shorted in the single digits. None of this means ZEN will suffer the same fate, it's just something to consider for anyone banking on huge gains. And no, I have no intention of selling at this point.
