Well we don't know for sure, but RNWF ran higher in 30 minutes than it ever did in a couple days time. That alone should say something about the float!
Power, I have to disagree with you here. Many people noted - on these boards - that they flipped their shares multiple times on Friday (one person flipped them 3 times!). That's one explanation for a portion of the volume. But moreover, this stock jumped 266% on volume barely over 150 million. Look around at some of these other stocks on ihub and compare those numbers. Very, very few move in the same way. Many have 200 or 300+ million shares traded and barely uptick. This stock tripled. Don't underestimate that at all.
