Your question could have several answers...some good and some bad. One thing for certain, posting on facebook and twitter does very little to move stock price.
Maybe they are still hoping for capitulation,maybe they want to stay quiet until financing is secured, maybe a new rumored CEO needs to make the deal, maybe the deal is not quite finalized or has contingents.
Regardless, we have recent activity growing and logical behind the scenes actions. It is only a matter of time before valuation corrects dramatically.
