Investors had braced for a much worse than expected 2nd estimate of 2nd Qtr GDP # and the actual number came in better than expected at 1.6% growth vs expectations for 1.4% growth.  The 1.6% still represents a slow down from 1st Qtr growth of 3.7% for 1st Qtr GDP and 5.7% for the 4th Qtr of 2009.  At this point, so much negative news is priced into bonds that it doesn't take much to surprise to the upside.
