Our read on ZMUN

ETF.net Research

CThe first ETF built purely on callable munis, tracking an index F/m co-developed with Bloomberg. It buys investment-grade tax-exempt bonds already callable or callable within three months, which keeps the maturity clock very short.

Stated mandate

The fund seeks to track, before fees and expenses, the price and yield performance of the Bloomberg Municipal Bond Currently Callable Index. It uses a passive representative-sampling approach focused on U.S. tax-exempt investment-grade municipal bonds that are currently callable or callable within three months.

Why people hold it

  1. 01A corner of the muni market nobody else had packaged: F/m calls it the first ETF dedicated to callable municipal bonds, on an index built with Bloomberg.fminvest.com
  2. 02The mechanism is the point: bonds callable now or within three months act like ultrashort paper, so price moves from rate swings tend to be muted.
  3. 03Interest is exempt from federal tax and, for some holders, certain state taxes. Spread across roughly 170 investment-grade issues, with cash paid monthly.
  4. 04No style drift: it is a passive representative-sampling fund, and the portfolio it holds matches the mandate written in its prospectus.

Worth knowing

  1. 010.30% a year sits above the short-muni group's 0.25% median, and far above the index giants VTES (0.05%) and SUB (0.07%).
  2. 02Callability cuts both ways: issuers can redeem these bonds at their option, capping price upside and forcing reinvestment at whatever rates exist that day.fminvest.com
  3. 03A 2025 launch that is still small and thinly traded. Short track record, and limit orders are the sane way in and out.
