MBS certainly would like to be rising today despite the GDP data, but with stocks now up 191.42 in the dow, the pressure is on bonds.

Again, treasuries are "taking the bullet" for MBS as the 10 year is still down 10 ticks, 5 year down 8 ticks while MBS down a mere 2 ticks.

I'm inclined to suggest it's a very good sign for MBS to be holding at 2 ticks down despite the GDP data + the 200 point rally in the dow.

Regardless, unless we take a sharp downturn, you are still quite safe to float.  If we do see that sharp down-tick, as always, we'll get you out of trouble before trouble comes looking...
