This alert is only relevant for lenders who repriced for the better in response to the mid-day rally and more specifically, to those who repriced for the better after 1:40pm ET.  Those lenders and only those lenders are now seeing about an eighth of a point of weakness.  In other words, if you're considering locking with one of those lenders, there's no sense in waiting as some could be considering a negative reprice. 

MBS are down 2 ticks (.06) on the day overall and 10yr yields are down roughly half a bp at 4.433.
