As stocks move lower into the afternoon, the uptrend in tsy yields has been mitigated enough to allow MBS to reconsider some nostalgic Friday Cliff-Diving.  More simply: MBS were trending down after breaking the intraday floor, but are now holding steady(ish).  Still plenty of downside pressure for all things bond-related, but no catastrophic sell off yet (and fingers crossed, not at all).  Stocks just fell past their late AM lows and are heading back towards unchanged.  If the "lever" is intact, this could help us stay afloat assuming the trend continues.
