Bonds rallied into the 9:30am NYSE open, but have been selling off modestly since then, mirroring the gains in equities. 

10yr yields are back to unchanged at 4.163.  MBS are also flirting with 'unchanged,' and down an eighth of a point from the 9:20am highs.  That's close enough to some lenders' rate sheet print times to entertain some small chance of negative reprices among the jumpier lenders.
