6.0's, though still not weak, are now one tick down on the day at 100-15.
More weakness in general has trickled into MBS price today though spreads are remaining on the positive side day over day. Hey! Any day in recent memory where we can get positive spreads, we'll take it.
The aforementioned reprices for the worse are something to be endured for long termers, whereas this additional risk of reprice may be impetus for short termers to cash in the gains from the past few days. There's no telling how long it will take to get these price levels back. It could be as soon as next week, or as far away as 3 weeks. Proceed accordingly.
