The Lowdown On Unconstrained Bond ETFs

 | Jun 30, 2016 07:15AM ET

Unconstrained bond funds are a relatively new category of the exchange-traded fund universe. The basic concept is to create an actively managed ETF with no barriers to sector exposure, position size, interest rate correlation, duration, or credit quality. Put simply – the gloves are off. The fund manager has discretion to go wherever they feel offers the most value to generate income, manage risk, and achieve capital appreciation.

Many investors think that ALL active funds are allowed this type of leeway. However, even well-known examples such as the PIMCO Total Return Active Exchange-Traded (NYSE:BOND) or SPDR DoubleLine Total Return Tactical (NYSE:TOTL) have prospectus limits for many characteristics. For instance, they may be able to choose between 0-15% emerging market exposure, but they can’t necessarily short a Treasury bond or suddenly go all in on bank loans and convertibles. There are guidelines that allow them some freedom within tolerable limits.

The benefit of this more traditional method is that the portfolio experiences less turnover and is more dependable for the fund investors. Even though a year later they might shift 25% of the underlying positions, it’s not going to look wildly different from today’s exposure. This is also how they generate alpha or manage risk in comparison to a benchmark such as the iShares Core US Aggregate Bond (NYSE:AGG).

By contrast, an unconstrained manager has the flexibility to do whatever they want. This allows them to seek unconventional returns versus traditional passive and even actively managed funds. That type of autonomy can be liberating for the manager and offer value to the investor. But it also comes with its own unique risks as well.

Of the 56 actively managed ETFs currently offered in the U.S. market, there are three with unconstrained mandates. These include:

WisdomTree Western Asset Unconstrained Bond (NASDAQ:UBND)

RiverFront Dynamic Unconstrained Income ETF (RFUN)

Virtus Newfleet Multi-Sector Unconstrained Bond (NYSE:NFLT)

Each variant is managed by a team of strategists that invest the portfolio according to their unique views on the interest rate and credit markets. The outlook of the manager and construction of the portfolio are two key characteristics that must be thoroughly researched when evaluating these funds.

Fortunately, the portfolio holdings for each ETF are required to be posted to the fund providers website on a daily basis for complete transparency. Furthermore, the managers often compile monthly or quarterly commentary as to why their portfolio is constructed and what challenges or opportunities they see on the horizon.

NFLT is the largest of this group with $173 million in total assets. They also charge the highest net expense ratio at 0.80%. While this may seem on the high side for a fixed-income ETF, it is reasonable to assume that more complex or unique strategies will charge a concomitant larger fee.

At the moment, this ETF is highly diversified with nearly 400 individual fixed-income securities. Their approach is to actively rotate between various sectors of the bond market (including international) according to their fundamental research. They are also focused on managing risk without the constraints of following a relative benchmark.
