Strong in The AM, Weaker in The PM Bonds improved fairly steadily in the AM hours.  After an initial glut of buying demand in the first hour of trading, there was a linear trend channel to the best level of the day right at noon ET.  After that, a similarly linear trend took bonds back toward (but not into) weaker territory.  None of the above occurred outside a range that we'd consider anything other than uneventful.  Overseas data and trading likely helped play a role in the ebb and flow.  The 3yr Treasury auction didn't have a big impact, but concession-building for tomorrow's 10yr auction could have contributed to the afternoon weakness.  Market Movement Recap09:31 AM modestly stronger overnight with better buying after the 8:20am CME open.  MBS up 5 ticks (.16) and 10yr down 4bps at 4.445 11:44 AM Best levels of the day with MBS up 6 ticks (.19) and 10yr down 6bps at 4.425 01:54 PM No major reaction to 3yr auction.  MBS still up 6 ticks (.19).  10yr down 4.1bps at 4.445 02:43 PM steady weakness in the PM hours, but still stronger on the day.
