Well, I would imagine there has been some sold and forgot where we were at the split, need to backtrack that - But the current structure with a 4M float is extremely low - From what I understand the remaining O\S is restricted for the non-profit.
Besides the recent 3rd party promo's I would expect the SP to vacilate like this, it seems to be like that on other stocks I have watched with really small floats.
I think you can safely say that the recent activity has been 95% new shares sold into the market. That's what Joe paid the promotes for, to promote the stock as he dumped the new shares.
So roughly about 2.4M added to the float. Just to be liquid enough to trade I would think even 4M dare I say, may not be enough. Wasn't there a huge debate on the sister stock with a much higher share count over much the same?
