FYI: Yesterday Columbia Threadneedle introduced an ETF that considers sectors of the municipal bond market. The Columbia Multi-Sector Municipal Income ETF (MUST) covers debt issued by state and local governments with some very specific exclusions that include California bonds and debt issued by U.S. territories, according to the prospectus.
MUST comes with an expense ratio of 0.28% and lists on the NYSE Arca.

Ted
