we've dropped 4/32nds in the past 3 minutes.  Potential reprices for the worse from lenders that set pricing early.  Not a certainty or even a strong probability at this point unless these levels fail to rally.

 Keep in mind that this will cause many lenders to hedge their pricing a bit more for the first rate sheet of the morning.  Make sure you are evaluating the day over day difference in MBS versus the day over day difference in YSP / discount cost.  If it seems like your pricing is ahead of the curve, those are the times to consider locking.
