I think those were a result of a sitting Bider hoping for a lower price ( I think it was 53 Bid and 55 Asked) and when the Asks did not come to him with closing bell he was left with the decision of leaving empty handed or meet the asks.
The fact that he came up instead of abandoning means that he really wanted the shares, which is a good sign ( also that anonymously! ).

Yessiree, we could use a bunch of that type.
But no sweat, news of one sort or another is inevitable in short time and the bidders will come and chase the asks, who in turn will run for safety of much higher prices.

I am also pleased, cheers. Ed.
