If anything that just indicates this is little more than end of month tape painting.
The PREM continued to spike down to the lowest it had been since 2:14 at 3:51 and then bounced higher into the close.
Hm, weird things going on with the futures after the close. Initially down almost $2, then bouced to almost up $2, then down $2 and now about down $1 at 4:06.
