That kind of depends what your focus is. All 4 are still in focus. They're just in different stages.
GRNO is already in the midst of a run, but doesn't look like it's squeezing yet. Perhaps very soon.
CDIV is the grandfather of the 4. It's been accumulated the longest as seems to have the potential to be the most explosive as it likely has the biggest short position of the 4.
EIGH is still in accumulation mode.
PNTV is the newest play and is still in accumulation mode.
