Not every lender will consider negative reprices this late in the day, but for those who do, there's the fresh new lows in UMBS 2.5 coupons!  We're now down an eighth on the day and more than a quarter point from the highs of the day.  Bonds have weakened in general this afternoon as stocks have rallied.  MBS have weakened more due to a less favorable supply/demand environment without the Fed in play since 1:20pm.
