Traders best friend is cash to trade. Money tied up is money "not making money." We may just have had a bunch of traders with the lack of sufficient cash to hold a position here until the stock begins to move.
Considering we still have a decent bid could be suggesting that "deeper pockets" could be accumulating that could actually hold a position.
Excuse me, must have not made my post clear. Was talking about the day trades and flippers that were taking there profits from other plays and buying here. Hope that clears things up.
