Interesting that Sept. #'s significantly lower across the board. Looks like SCHB & NITE control the show but I see what you mean about ARCA. It seems like they showed up everytime there was momentum for the past few days. Maybe someone has a clearer view of this than I do.
If you haven't read this, you may want to. 8/25 sb-2a filing was for 2.5 bil but doesn't mean they will dilute all these shares. Dilution should be influenced by share price. Meaning the higher they can sell these shares dilution will be minimized. http://www.otcbb.com/asp/Info_Center.asp
