Anyone who doesn't think there are eyes on this is mistaken.
Pre-open the bid was approx 110,000 @5.1, sell 137,000 @5.5
On open 28,473 @5.1 was dropped over the 5.5 sell to take it down. Now the sell is 28,472 @5.4 while the bid is up 94,102 @5.2
Someone somewhere doesn't want this getting away just yet.
Fun and games while treatment of the final patient in two weeks or so draws ever closer...
