After rallying directionally from 11am, both Treauries and MBS have broken from those trends and gone sideways into 3pm. To be sure, some positive reprices may still be out there, but if you've already seen one, this is sort of a heads-up that you're not likely to see another one from the same lender. Also bear in mind that some lenders (only a select few, really) have been known to reprice negatively on afternoons like this where we've rallied for most of the day and begin drifting off into the close.
Whatever the case, Fannie 3.5s are back down to 103-09, getting closer to the 103-07 / 103-08 pivot zone. 10's are back into negative territory, up less than a bp at 2.187, but looking like they want to break higher. "Stay frosty" = stay cautious if you need to be. No negative reprice risk yet based on price levels, but the rally is over and the sideways grind is at risk of slipping a bit.
