MBS are now down 6 ticks (.19) on the day and just over an eighth from PM highs.  Lenders who repriced for the better earlier could technically justify a negative reprice. 

Prices are no lower than they were earlier this morning so lenders who priced after 9:30am are at no legitimate risk of repricing (unless they repriced for the better after initial rates).

The best way to use this alert is as a cue to lock if you were already planning on locking today.  Otherwise, this isn't remotely enough movement to change anything in the bigger picture.
