FYI: While Puerto Rico continues to dominate the muni market headlines, trading in Puerto Rico bonds has totaled less than 3% of muni trading volume so far this quarter (through May 15, according to MSRB data from Bloomberg).
With the bulk of attention focused elsewhere, muni yields have generally moved lower so far this year, lifting most of the muni indices into positive territory. Bond prices rise when yields fall.
