Everyone has sold something at a loss at 1 time or another,even the big boys or large funds!Black box trading do rule some funds also as to try to "take some of the human error away." Or mayby someone just needs the money alloted somewhere else , so the big funds kind of doing each other favors kind of thing,as what comes around goes around.

Iv'e also seen this many a time that lot of vollume with a great price attached and then stock goes to the moon,and not necessarlly right away,but soon.

Whatever it is I see it as all good.
