Amid the US/UK trade deal press conference and Trump's touting of the stock market, stocks are ripping higher and bond yields are following (even if not "ripping").
10s are now up 6bps at 4.331 and MBS are down more than a quarter point. Most lenders could justify a negative reprice now, except for those who price very late in the morning (i.e. after 10:30am ET).
