What’s The Strategy Of BOXX ETF?

For those who aren’t necessarily familiar with a “tax efficient cash management tool” style of asset allocation, let’s first define what it is and then explain this strategy in practice by giving some clear examples.

Cash management tools are generally referring to assets that have very low duration and very low risk and very low returns. We are talking about cash, CDs, money markets, treasury bills, and so forth. And in this instance, we are also including the more esoteric “box spread” in this category.

The tax-efficiency aspect is something we always think about as tax-sensitive investors, however, we can only operate within the law, like everyone else. That said, the ETF structure has some unique features that, we believe, allows us to be relatively tax-efficient in the delivery of the risk/return tied to box spread transactions.

BOXX ETF seeks to be a tax-efficient cash management tool offering tax efficiency, treasury bill risk and treasury bill returns as investment goals

Unique features of BOXX ETF from Alpha Architect - digital art

Unique Features Of Alpha Architect 1-3 Month Box Fund BOXX ETF

Let’s go over all the unique features your fund offers so investors can better understand it.

What key exposure does it offer?

Is it static or dynamic in nature?

Is it active or passive?

Is it leveraged or not?

Is it a rules-based strategy or does it involve some discretionary inputs?

How about its fee structure?

We focus on delivering the return on 1-3 month box spreads. A box spread is a 4 leg option strategy that is designed to synthesize the funding rates from option markets. In general, the risk on these trades is similar to treasury bills, and the returns are also similar. A detailed explanation of box spreads is available here

To our knowledge, box spread exposure has never been delivered via a 40-Act mutual fund or ETF. So this strategy is certainly innovative and unique, almost by definition. Our partners in this product, Arin Risk Advisors, have been trading and operating in option markets for 20+ years. They bring a unique trading and execution expertise that is incredibly difficult for other operators to replicate.

What Sets BOXX ETF Apart From Other Short-Term Fixed Income Funds?

How does your fund set itself apart from other “short-term fixed income, money market or brokerage account products” being offered in what is already a crowded marketplace?

What makes it unique?

The key difference is in how the returns are sourced. Most limited credit risk fixed income boils down to treasury bills, which relies on the US government not defaulting and them paying their debts. Box spread returns are backed by OCC, which has its own credit risk policy, but their situation is different than the US government. One key example is that OCC is generally not subject to the politics of ‘debt ceilings’ that can cause risk in the treasury bill market.

The other difference is that box spreads have historically earned slightly higher returns than equivalent duration treasury bills. So there is an opportunity, over time, to earn higher returns on box spreads versus treasury bills. There is a recent paper on this topic via

What Else Was Considered For BOXX ETF?

What’s something that you carefully considered adding to your fund that ultimately didn’t make it past the chopping board?

What made you decide not to include it?

We spent a lot of time developing this product – 5 yrs+ in fact. But the overall interest rate environment was terrible and short rates were often 50bps or less. This meant that nobody really cared about cash management. However, now that cash rates are 4-5%+, cash management became an important topic and we thought that BOXX would be a unique offering that was highly differentiated from all of the treasury bill products on the market.

When will BOXX ETF perform at its best and at its worst? Digital art

When Will BOXX ETF Perform At Its Best/Worst?

Let’s explore when your fund/strategy has performed at its best and worst historically or theoretically in backtests.

What types of market conditions or other scenarios are most favourable for this particular strategy?

On the other hand, when can investors expect this strategy to potentially struggle?

I would refer you to the recently published paper on this topic, which is independent of our organization.

The chart below outlines the SPX box spread rate against equivalent treasury bills/bonds over time. In general, the blue line is above the red line throughout history.

Why Should Investors Consider Alpha Architect 1-3 Month Box Fund BOXX ETF?

If we’re assuming that an industry standard portfolio for most investors is one aligned towards low cost beta exposure to global equities and bonds, why should investors consider your fund/strategy?

BOXX is not meant to make you rich. This is a cash and cash equivalent holding that is meant to deliver treasury bill type risk and treasury bill type returns. So investors would use this for strategic or tactical cash positions. And perhaps there are retirees and others who live on fixed income where there could be a place for something like BOXX.

How Does BOXX ETF fit into a portfolio at large - digital art

How Does BOXX ETF Fit Into A Portfolio At Large?

Let’s examine how your fund/strategy integrates into a portfolio at large.

Is it meant to be a total portfolio solution, core holding or satellite diversifier?

What are some best case usage scenarios ranging from high to low conviction allocations?

Same as above, this is a cash and cash equivalent vehicle. The one interesting, but complicated aspect of BOXX, is the taxation. But we recommend you consult your tax advisor and/or reach out to us with specific questions on how this works since it is beyond the scope of this discussion.

The Cons of BOXX ETF

What’s the biggest point of constructive criticism you’ve received about your fund since it has launched?

Primarily that the box spread concept is complex and nobody has ever heard of it. In short, outside of option market makers and proprietary trading professionals, “box spread” is essentially a foreign language.
