Mr. Mustapic (insider) sold 125,000 shares on the open market for average 1.12 per share. If he had any inkling that any off take, buyout, major partner, etc was coming down the road, he would not have sold those shares. Any of the these major news annoucements would have sent the stock up more than a dollar very quickly.

On the other hand, if he saw their was nothing coming in the foreseeable future and the ZEN stock price would just be drifting lower, then sell some shares now. That is exactly what has happened.

I do not expect any significant news unless something has happened the insiders were not expecting after he sold the shares. Still uderwater and waiting for significant news.
