Our read on MFLX
DThe boutique corner of the muni aisle: roughly 70 bonds instead of a thousand-line index, monthly payouts, and a mandate to keep at least 80% of net assets in interest exempt from regular federal income taxes.
The Fund seeks current income by investing at least 80% of its net assets in municipal debt securities whose interest is exempt from regular federal income taxes.
Why people hold it
- Tax-free by design: at least 80% of net assets sit in municipal debt whose interest is exempt from regular federal income taxes.
- Income lands monthly, so the tax-exempt cash flow arrives on a paycheck-like rhythm rather than quarterly lumps.
- Roughly 70 bonds, not a sprawling index sleeve. This is the hand-picked, flexible end of munis, where individual credit calls actually show up in the portfolio.
- Live since 2016 under First Trust, giving it a track record across a full rate cycle rather than a fresh-off-the-line launch.
Worth knowing
- You pay up for the hands-on approach: 0.75% a year versus a 0.30% muni-fund median, while index anchors like VTEB and MUB charge a few basis points.
- Small asset base and thin trading. Limit orders matter here, and spreads can be wider than the household-name muni index funds.
- The exemption covers regular federal income tax only. State treatment and the income-first, concentrated tilt make this a different animal from a broad muni index.
