Honestly the "large volume/minimal movement in price" thing we've seen a million times. My guess is one of two things: Shorts are back at it again or someone(s) is/are taking profits from the capital raise into a buyer. Maybe some follow the leader buying from others getting in - like has been said here over and over again needed to happen.
And with respect to the institutional ownership, I have to be honest and say I have not looked at that for some time (gave up actually)and was surprised to see what appear to be quite a few new ones there including some index funds. Was not aware they were added to any new indexes but based on the company's lack of enthusiasm about sharing information now, I am not surprised that slipped by unnoticed.
Regardless, at first it was unclear to me how they could have accumulated those positions with the limited volume that we have seen for a very long time but probably a lot of those shares were picked up outside the market from dumpers like Faud and that is why we really saw no price movement. Maybe some of it was the volume we saw late January/early February too. That might explain some of the run up in price then.
My only hope is that these guys now committed take a proactive role in helping management get to work creating value instead of destroying it.
