It's a clever tactic / head fake, imo. I've seen it before. We shall see.
That's the same sort of tentative conclusion I've drawn on some of the normally very small and very late isolated AH trades.
As I post this though we have a pre-market $0.5201 x 2,689 trade, the same price as yesterday's close. Maybe that will ameliorate the possible effect that earlier $0.49 trade.
