Technical Breakout in Treasuries. Does it Matter? Bonds began the day in much weaker territory as Treasuries followed European yields higher after a series of stronger PMIs overnight. Domestic traders added to the weakness early with 10yr yields hitting their highest levels since November.  Bonds found their footing after an as-expected JOLTS report and MBS even made it all the way back to "unchanged" just before 3pm.  Nevertheless, 10yr yields had broken their recent 4.32% ceiling.  As always technical levels don't predict the future.  This breakout reinforces the headwinds of the past few weeks and acknowledges the risks associated with the incoming data.  If that data is friendly, this will not look like an important technical breakout in hindsight.  But the opposite is also true: stronger data would make this breakout look like ominous foreshadowing.
