I'm sorry - pinksheets is not the best place to go since this is a fully reporting NASDAQ company. Besides, there is NOTHING in the filings to indicate any sensible reason for the sell off. The largest shareholder has been on a buying spree spending over $4M the past few months and I will venture to say he is buying A LOT more down here.....
THIS WAS A SHORT ATTACK BROUGHT ON BY A FEW ROGUE SELLERS HITTING MM's with shares. The mm's then turned around and sold them back to other mm's creating a rapid downward spiral.
