It seems that most employees are highly paid "executives" who sit comfortably at some very nice office located in Houston. Petrodelta is basically a "joint venture" in which Harvest is a minority partner, and probably does not have much weight in final investing and growth decisions. All Petrodelta employees are in PDVSA's payroll, and they are forced to be loyal to PDVSA and most of all, to the "revolutionary" leader Hugo "the red pig" Chavez. These should be the reasons for this stock to go nowhere for a while. This stock should go up if its other international ventures are successful. And there is no way to know that now. It would take a least a couple of years to be able to see and to evaluate results. The only short-term catalyst that I can see is the company's investment in continental USA.
