Somebody sold 2,000 shares or maybe they, the (MM's) shifted some to create some life before everyone fell asleep. It is a buying opp but most are holding as much as one can afford a this time, I know I made a buy last week.
Any member of this board or long would never sell 2,000 shares for $570 so if the MM's want action, of course absent NEWS, then they have to raise the ask way way up.
In the meantime we wait!
