MBS Continue Solid Performance After Economic Data

So far, today has been more about a relatively contained, sideways momentum in response to a more significant movements in the overnight session.  Case in point, 10yr yields moved 5 bps between Friday's close and today's open but have traded a tight range of less than 2bps all morning.

The 10am economic data did little, if anything, to sway Treasuries from their sideways trend or to sway MBS from their "slightly-better-than-sideways" trend.  More on that in a moment, for now, here's a look at some of the trends we're tracking on the MBS Live Dashboard:
