MBS Live: MBS Afternoon Market Summary
As far as domestic trading hours were concerned, today was even flatter than yesterday's exceptionally well-contained session for both MBS and Treasuries.  That said, both sides of the market began in weaker territory owing to a "take your pick" assortment of European market movers with Germany's much better than expected ZEW survey being the standout.  Other European events contributed to a general "risk-on" move into the domestic session with news that Greece had reached their target amount for a required debt buyback overshadowing domestic data in the morning.  Later in the session, we'd learn that the prices agreed to in that buyback were high enough to put Greece 2% and change over the limit for their 2020 debt-to-GDP target (but what's a few hundred million Euros among friends?).  That news may have helped reinforce the support that Treasuries and MBS were already seeing.  Additionally, Boehner and Reid broke out the banjos for quick duel, to the tune of "Gettin Nuttin' For Christmas."  Indeed, Fiscal Cliff headlines continue to be "nuttin' but bad," both in the sense that they aren't speaking to progress and that they're utterly devoid of substance.  The bigger preoccupation, in lieu of catchier Fiscal Cliff tunes, is tomorrow's FOMC Announcement--important in that it SHOULD more clearly spell out the way in which the Fed will continue buying Treasuries in 2013.

Afternoon Reprice Alerts and Updates
Below is a recap of instant Reprice Alerts and updates issued via email and text alert to MBS Live subscribers this afternoon.
3:30PM  :  Late Stock Slide Helps Bonds, Reprices Unlikely But Possible
MBS just inched into their highs of the day with Fannie 3.0s down only 1 tick at 104-31+. There's little to lean on by way of market movers apart from Senator Reid saying it will be hard to reach a deal on the Fiscal Cliff before Christmas.

If that's our market mover, markets paid it almost no mind for at least 5 minutes after it hit the wires (that's uncommon). Whatever the case, stocks began to slide shortly thereafter, and are currently within a few S&P points of opening levels--8 points from mid-day highs.

10yr Treasury yields stepped back from their ledge in the mid 1.65's and moved to mid 1.64's. Riveting...

Bottom line, there's a small, lingering possibility that we'd see a positive reprice or two, due more to the microscopically positive stability rather than empirical improvements in prices. Qualitative > Quantitative. It has been known to happen, but we wouldn't plan on it. Tomorrow's FOMC announcement continues to keep trading ranges compressed.
1:21PM  :  Auction Undetectable, Sideways Grind Continues
MBS prices are at the same levels as the morning update and haven't strayed more than 2 ticks in either direction since then. The 3yr auction was exactly as expected in terms of yield (.327) and much weaker-than-average in terms of bid-to-cover (3.36 vs 3.71 recent average). Also exactly as expected was the auction's inability to suggest any response in the realm of longer Treasury maturities, let alone production MBS.

10yr yields leveled off earlier this morning after topping out at 1.658 and with few exceptions, have traded between there and 1.648--a 0.01% range for almost 4 hours now... 10's are currently at 1.654 while stocks are having their best day in a while with S&Ps up over 15 points. Fannie 3.0s are down only 4 ticks (post-roll) at 104-28.
