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.

“…munis are well-known for delivering 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.

Discount brokers expand their lineup of commission-free ETFs

Last month, Fidelity and Schwab announced an expansion of the commission-free ETFs offered to their customers. We touched on this point in a recent ETFMathGuy Blog post. But, we didn’t get into much of the details of what an expanded lineup of commission-free ETFs would mean for an investor. So, in this post, we will dig into some of cost details, like expense ratios and bid-ask spreads.

Fidelity’s expanded list of commission-free ETFs for 2019

The announcement on February 12, 2019 indicated over 500 commission-free ETFs. As a current Fidelity customer, I was delighted to see the expansion. Unfortunately, as of March 16, 2019, Fidelity’s ETF screener revealed only 357 ETFs as commission-free. Note that this screen is only available to current Fidelity customers.

Given the strong reputation Fidelity has in the investment community, I am sure they will follow through soon with their fully expanded lineup of more than 500 commission-free ETFs. However, it is unfortunate that Fidelity’s press release didn’t give a specific timeline for when the fund expansion will occur in its entirety, except to say “…in the coming months”.

Schwab’s expanded list of commission-free ETFs for 2019

Schwab now claims 500+ commission free ETFs. We downloaded the list of Scwhab’s expanded commission-free ETFs, and found exactly 500. So, we are not sure where the “+” comes from, but this is still quite a large lineup.

How do the expense ratios compare?

Expense ratios are important, as they are a continuous drag on returns. So, ETFs with lower expense ratios than others tracking the same index should produce higher returns. Using data obtained from ETF.com, we created charts to show a histogram of expense ratios for the commission-free ETFs from Fidelity and Schwab.

What does this data show us? Generally, expense ratios are lower for Fidelity’s commission-free ETFs. But, there are quite a few (about 20% or 1 out of 5) of Fidelity’s commission-free ETFs with an expense ratio between 0.4% and 0.5%. So, with a little careful selection, Fidelity offers a larger fraction of commission-free ETFs at lower expense ratios then Schwab.

How do the Bid-Ask spreads compare?

Bid-ask spreads are the costs incurred when an ETF is bought or sold, and which I discuss at length in my article “Is there a free lunch in commission-free ETFs?“. Once again, using data from ETF.com, we see that nearly 80% of the commission-free ETFs from Fidelity have spreads below 0.2%. This compares to about 74% of funds from Schwab that have spreads below 0.2%. Thus, Fidelity’s commission-free ETFs have generally lower spreads then those offered by Schwab. So, for more active investors, Fidelity’s commission-free ETFs appear to have the advantage of lower transaction costs.

Conclusions

Competition for investor assets continues, to the benefit of investors using commission-free ETFs. In this post, we discussed some of the details of the updated lineup of commission-free ETFs now offered by Fidelity and Schwab. We find that while Schwab still offers more ETFs commission-free, Fidelity’s costs are generally lower. Lower expenses are important, as they can often lead to higher returns for funds tracking similar indices.
