Muni Exchange Traded Funds vs. Mutual Funds

ETF’s

Exchange Traded Funds have become increasingly popular in recent years. These funds are for the most part passively managed, track indices, and have low expense ratios compared to the average mutual fund. ETFs can be traded intraday, shorted, and bought with margin. Mutual Funds do not offer the same features. There are no size minimums to invest in ETFs. This makes them popular with smaller investors. Exchange Traded Funds are usually a more tax-efficient vehicle than mutual funds because they don’t realize gains or losses when selling securities. ETF’s can be concentrated to give an investor exposure to a specific segment or market, such as precious metals, single countries, foreign currencies, and U.S. Treasury Bonds. It should be no surprise that the ETF has finally discovered the Muni market.

The Muni Bond Market

The Municipal Bond market is a highly fragmented market of over 50,000 different issues. Last year, there was total issuance of $388 billion from 12,706 different deals for an average size of $31 million per deal. The market is a collection of regional markets. Each state has different tax rates and different infrastructure needs. The Individual Investor (as a whole) is the largest investor class of muni bonds accessed via individual securities, separately managed accounts, mutual funds, and closed-end funds. These investors typically purchase munis because of the tax advantages of owning tax-free bonds.

Historical Problems Creating Muni Indices

The fragmentation of this market has caused problems in the past with the creation of a viable index for munis. Due to the wide bid/ask spreads and tax consequences of trading, individuals tend to buy and hold muni bonds to maturity. This strategy means that after a bond deal is issued, the amount of trading in that security diminishes rapidly over a short period of time. This makes price determination difficult for any individual security, because actual trades do not take place. It is this lack of actual price determination through trades that has caused problems with Muni indices in the past. This was evident with the Muni bond contract. The CBOT finally stopped trading this contract in 2006, because of problems with the index that led muni dealers to look for alternative hedge vehicles to hedge their inventory.

There are currently several indices money managers use to measure performance which work well for their purposes. These indices are priced daily and are meant to reflect changes that have taken place in the market. The CBOT muni index was a live index that needed to be priced continually. The current plan is to price the relevant ETF index on a daily basis. Most ETF’s in other markets trade continuously and can be compared to a transparently priced index which also trades continuously, such as the S&P Index. Without transparent continuous pricing, muni ETF’s may be subject to some of the same issues that brought down the CBOT muni contract: manipulation by hedge funds and lack of pricing relevancy.

Portfolio Construction And Performance

The ETF faces constraints which will affect its ability to offer good value to its shareholders. The ETF must only purchase bonds from large deals. The table shows the different size limitations of the deals they may purchase. This will limit their ability to invest in any cheap smaller regional issues that may come to market. The purpose of this restriction is to make sure they are investing in liquid names. There are also limitations as to the issue’s purpose. For example, some ETF’s can’t invest in tobacco bonds, hospitals, or housing bonds. Neither one can invest in AMT bonds.

ETF Advantage May Not Apply to Muni Investor

Marginal tax rates determine the attractiveness of muni bonds for any given investor. High Net Worth Individuals with significant levels of taxable income find munis especially attractive. These investors normally have large sums of money to invest and don’t benefit from the ability to invest small sums of money in an ETF. There may be adverse tax consequences of selling holdings in these funds, so it is unlikely that the ability to liquidate holdings intra-day would offer much benefit to these investors. When we compare the tax free ETF to Vanguard mutual fund, we see little benefit to purchasing the ETF, and our guess is that the ETF will have difficulty generating higher returns than the mutual fund because of its constraints.

Conclusion

It will be interesting to see how successful the muni ETF is in the future. We expect this success to be somewhat dampened due to difficulties in index construction and the nature of the muni investor.
