Albeit briefly, the price curve on the 5.5% dipped blow 100-05 for about 25 seconds, we're back up at 100-07 now.

Wow! It's volatile!  Be ABSOLUTELY READY FOR ANYTHING!  That means lock sheets should be in hand.  Again, if your lender hasn't released pricing yet, we're still floating, and again, if they have, they may be spooked enough for a price worsening.  Be alert!
