Centennial (CDEV) is one of the weaker shale players hanging by a thread and a prayer, literally. Very poorly hedged, cash flow deficit for years, plus their acreage is not that great. Granted it isn't land locked like some others in the N. Dakota basin. <br /> <br /> Every now and then they pump it up a bit during earnings season, much the same as Oasis. C'mon, you don't need volume of 10 mil shares to go up by 5 cents!!
