Commission-free Municipal Bond ETFs and a diversified portfolio

Commission-free ETFs cover a number of important asset classes, including municipal bonds. “Muni” ETFs can add an important asset class to a diversified portfolio, as returns often differ from other bond ETFs. “Muni” bond ETFs also carry the important benefit of tax-exempt interest.

Not surprisingly, discount brokers like Fidelity don’t permit their use in tax-advantaged retirement accounts, like IRAs. Since there are currently 46 municipal bond ETFs, most retirement accounts really don’t have access to the full list of commission-free ETFs advertised by discount brokers. The chart below summarizes the number of commission-free ETFs available. It includes the five discount brokers analyzed regularly by ETFMathGuy to develop optimal portfolios.

This chart shows that no single broker offers all 46 “muni” ETFs commission-free. But, Schwab and Fidelity offer the most at 12, followed by ETrade (11), Ameritrade (10) and Vanguard (1).

So, what does this mean for a diversified portfolio with commission-free ETFs? ETFMathGuy will be expanding portfolio construction to include both IRA accounts (that don’t include municipal bond ETFs) and taxable accounts that do.

Please be sure to check back at the beginning of April to see how municipal bond ETFs affect the diversified portfolios created by ETFMathGuy.
