Rate Rally Returns With Help From Housing Data How about a good, old-fashioned market reaction to weaker economic data?  We've seen it a few times recently, but not in response to an "almost never" market mover like New Home Sales.  Today was an exception owing to the 591k headline vs a 750k forecast.  Bonds were already edging into stronger territory overnight on weak PMI data in Europe.  Domestic data took it to the next level with stocks and bond yields moving lower in unison.  Even after stocks attempted to recover, bonds retained most of their gains--especially in the short end of the yield curve given the slowing seen in the pace of Fed rate hikes (eventually).
