Production MBS coupons are outperforming "up in coupon" MBS this morning. In terms of MBS's relative value, 4.0s and 4.5s yield spreads are tighter vs. benchmark TSYs (MBS outperforms TSYs). The stock lever and its effect on TSY yields continues to control intraday MBS price trends. As we have drawn closer to notification day (class A is tomorrow) the MBS market has gone silent as most market participants have already rolled their paper trading positions ahead to May. On the supply heavy side of the stack (production coupons) the Fed continues to easily overwhelm any originator offerings of available for bid MBS pools.  Trading activity as slowed to a standstill. We are nonetheless still improved on the day....

The FN 4.5 already ran through its previously marked 101-24 overhead resistance zone. However soon after running through that resistance the MBS market consolidated its gains. If stock markets continue to express their feelings that the month long rally in equities was nothing more than a "bear market rally", production supply MBS coupons may further benefit from any flight to safety yield curve flattening.  Next level of resistance is 101-31. Aggressive lenders will be more willing to improve rate sheets if the 4.5 can demonstrate some stability over the 101-24 resistance zone.

The Dow is down 1.73%. The S&P is down 1.54%. The NASDAQ is down 1.86%.

Anyone want to take a stab at why the beginning of the month is generally a supportive time for MBS?
