For perspective, I've included a comparison of the worst % change performers since I started this analysis against a Morgan Stanley municipal fund.
Note that the BlackRock Strategic Municipal Trust is down more than 5% relative to the MS fund YTD. The Virgina fund seems to have the worst time of all, trading at over 10% below the MS fund YTD. There are a number of possible reasons for this, though none seem particularly clear. Some of this might be competition taking its toll in the CEF market, some an instance of issuer credibility premium, and obviously some related to yield changes, but overall, there is still some broad and high-dollar-value selloff going on in municipal bond CEFs.
