CAOS ETF Review: The Strategy Behind Alpha Architect Tail Risk ETF

Chaos. That’s what you can expect to find in any hotel room or AirBnB I’m staying in.

I travel for a living and if there’s one thing I can count on, it’s that as soon as I check in and my luggage hits the ground, its contents will inevitably explode across the room. Camera gear, electronics, clothing – you name it!

However, today we’re talking about a different type of chaos and how it relates to turbulent market conditions.

As investors, we’re often prepared for the good times loading up on offensive assets.

But what about tail risk strategies and hedging against severe drawdowns?

Enter the room CAOS ETF.

It’s better known as Alpha Architect Tail Risk ETF.

We’re fortunate enough to have Wes Gray with us to discuss the strategy behind this particular fund.

Without further ado, let’s turn things over to Wes to find out more!

Meet Wes Gray of Alpha Architect

After serving as a Captain in the United States Marine Corps, Dr. Gray earned an MBA and a PhD in finance from the University of Chicago where he studied under Nobel Prize Winner Eugene Fama. Next, Wes took an academic job in his wife’s hometown of Philadelphia and worked as a finance professor at Drexel University.

Dr. Gray’s interest in bridging the research gap between academia and industry led him to found Alpha Architect, an asset management firm dedicated to an impact mission of empowering investors through education. He is a contributor to multiple industry publications and regularly speaks to professional investor groups across the country.

Wes has published multiple academic papers and four books, including Embedded (Naval Institute Press, 2009), Quantitative Value (Wiley, 2012), DIY Financial Advisor (Wiley, 2015), and Quantitative Momentum (Wiley, 2016). Dr. Gray currently resides in Palmas Del Mar Puerto Rico with his wife and three children.

I had been an investor in AVOLX, when it was mutual fund, for several years. The product provided a unique tail risk exposure that didn’t have the typical return drag tied to other tail risk funds. Unfortunately, the fund was in the mutual fund wrapper and wasn’t that tax efficient.

I eventually asked Arin Risk Advisors, the brains behind the operation, if they would consider letting us convert their mutual fund into an ETF. This would, selfishly, make the fund more tax-efficient for my personal needs, but this would also make the strategy more readily available for the broader market of ETF buyers.

What’s The Strategy Of CAOS ETF? - Digital Art

What’s The Strategy Of CAOS ETF?

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

Tail risks are generally defined as 25%+ drawdowns in the market that happen in short order – call is less than a month.

The best and most recent example is March 2020 during the COVID pandemic scare when markets blew up intra-month.

CAOS seeks to solve the problems tied to other tail risk investments by providing a tail risk hedge, low return drag and by being tax-efficient

Unique Features Of Alpha Architect Tail Risk Fund CAOS 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?

CAOS, which is almost 10 years old at this point (AVOLX was the prior ticker when it was a mutual fund before we did a tax-free conversion into an ETF), seeks to do 3 things: hedge tail-risk events, minimize return drag, and minimize tax drag.

The fund has delivered on the first 2 objectives by 1) providing positive returns during tail risk events and 2) having positive carry of the life of the fund. And now that the vehicle is delivered via the ETF wrapper, which has additional tools to minimize tax burdens, we are confident on a go-forward basis that we can accomplish all 3 objectives.

The strategy, at its foundation, owns out of the money puts to provide the tail risk protection. This is what any tail-risk fund has to do if they want to deliver a hedge against large market drawdowns. However, the trick is figuring out how to pay for these puts without burning all your money on fire along the way (which is common among all the tail risk strategies we see on the market).

This is done by actively buying and selling different option spread strategies and capturing ‘theta’ or time decay. These option strategies help pay for the tail risk hedges, on average, over time. Or at least that is our goal – figure out how to deliver tail risk hedging, while providing positive carry along the way.

The holy grail of ‘insurance’ in some sense. The objective is not easy but has been achieved over a long period of time thus far, which gives us confidence we can continue to be successful on a go-forward basis.

What Sets CAOS ETF Apart From Other Alternative Funds? Digital Art

What Sets CAOS ETF Apart From Other Alternative Funds?

How does your fund set itself apart from other “tail risk hedging products” being offered in what is already a crowded marketplace?

What makes it unique?

As mentioned above, CAOS is almost 10 years old and delivered what amounts to the holy grail of tail risk hedging products: 1) tail risk protection during tail risk events and 2) positive carry.

The rest of the ETF marketplace, to our knowledge, cannot make these statements regarding their tail-risk products.

What Else Was Considered For CAOS 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?

This was a MF conversion with a long-term track record of success. Many of the bugs had been worked out years prior to us converting this into an ETF via the CAOS ticker.

When Will CAOS ETF Perform At Its Best/Worst? Digital Art

When Will CAOS 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?

The strategy is designed to make money during violent and swift market corrections. So 25%+ drawdowns that happen within a month’s time period. And we want to deliver positive carry on the fund over the long-haul.

What the fund doesn’t do is make money all the time and protect against all losses. This would be unrealistic, obviously. So we knowingly structure the fund to have exposure to losses in the 0-20% range, especially if these are ‘bleeding bear’ market type losses that happen over an extended period. 2022 is a great example of the worst conditions for CAOS – a slow and steady bear market, but a bear market that isn’t that extreme.

In normal markets, we expect the fund to have positive returns and positive beta to the broad us stock market.

Why Should Investors Consider Alpha Architect Tail Risk Fund CAOS ETF? Digital Art

Why Should Investors Consider Alpha Architect Tail Risk Fund CAOS 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?

The standard 60/40 stock/bond portfolio works okay when bonds go the opposite of stocks during a market panic. However, this relationship is precarious at best. A more robust portfolio needs to be better diversified and add strategies that minimize tail risk damage – this is what CAOS is designed to do.

We recommend it be used as a replacement for a portion of one’s fixed income portfolio and/or a substantial addition to a generic alternative/diversifier portfolio.

How Does Alpha Architect Tail Risk CAOS ETF fit into a portfolio at large - digital art

How Does CAOS 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?

Let me explain how I use it, personally. I am essentially all-in on our core long-only global factor products – QVAL/QMOM/IVAL/IMOM. This exposes me to a lot of factor risk and a lot of beta risk. I offset this risk via 2 exposures: trend following managed futures and tail risk hedging. The managed futures are there to protect against long protracted drawdowns and the tail risk hedge, ie CAOS, is there to protect against quick/violent market drawdowns.

Now, how one sizes these positions will obviously depend on how much risk you want to hedge. I can’t answer that question without knowing a lot about the individual circumstances of the situation, but generically speaking, I think replacing a large portion of one’s no/low credit risk fixed income is a reasonable idea. High grade fixed income isn’t a great tail hedge and is generally tax-inefficient, so it strikes out on 2 fronts in my book.

Cons of CAOS ETF - digital art

The Cons of CAOS ETF

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

Mainly that we haven’t marketed it and/or explained it that well.

We are working on that and now have an overview deck and marketing materials related to the fund. Our firm has been exceptionally busy launching new products and our marketing/distribution capabilities are scarce…but we are in the long-game with all products under the Alpha Architect umbrella, which means marketing/distribution/etc can wait.

We are in no rush to grow, we are in a rush to build and deliver what we think are unique, affordable, exposures that solve a problem in one’s portfolio.

The Pros of CAOS ETF

On the other hand, what have others praised about your fund?

The historical performance track record, which has delivered on tail risk protection, without massive return drag (actually had positive returns!)

Q10) We’ll finish things off with an open-ended question. Is there anything that we haven’t covered yet that you’d like to mention about your fund/strategy? If not, what are some other current projects that you’re working on that investors can follow in the coming weeks/months?

Nothing comes to mind. We launch funds very rarely and typically spend 3+yrs on product development. As of now, we have no new ideas on the horizon, but that could change.

CAOS ETF — 12 Essential FAQs on the Alpha Architect Tail Risk ETF (CAOS)

1) What is CAOS ETF in one sentence?

CAOS (Alpha Architect Tail Risk ETF) is a rules-driven tail-risk hedge that aims to pay off in violent, fast equity selloffs while targeting low ongoing return drag and tax efficiency via the ETF wrapper.

2) What does “tail risk” mean here?

“Tail” refers to rapid, severe drawdowns (think ~25%+ in ~a month), like the March 2020 COVID collapse—events where traditional diversification often fails and explicit hedges can shine.

3) What’s the core strategy CAOS uses to hedge?

The fund owns out-of-the-money (OTM) equity puts to create convex payoff in crashes, and actively trades option spreads to harvest theta (time decay) that helps finance the puts, seeking positive carry over the long run.

4) How is CAOS different from many tail-risk products?

CAOS is designed to do two hard things at once:

  • Hedge tail events (positive convexity in crashes), and

  • Minimize return drag by offsetting premium spend via option income strategies—an approach that historically has produced positive carry across the fund’s life (inclusive of the predecessor mutual fund).

5) Is CAOS static or dynamic? Rules-based or discretionary?

The foundation (long OTM puts) is persistent, while spread selection and management are actively implemented to capture carry and fund the hedge. The process is rules-informed and manager-directed rather than purely passive.

6) Does CAOS use leverage?

The fund isn’t designed to lever equity beta. Options are notional-efficient instruments, but the intent is tail protection + carry, not magnifying market exposure.

7) When might CAOS perform best—and worst?

  • Best: During swift, violent selloffs (sharp equity crashes).

  • Worst: In slow, “bleeding” bear markets (e.g., 2022-style), where losses accrue gradually and crash convexity is less rewarded; also, strong bull markets can see the hedge lag broad equities.

8) What does “positive carry” mean in this context?

Many hedges cost money over time; CAOS seeks to offset (or exceed) that cost by systematically selling option spreads and capturing time decay, aiming for net positive carry while keeping crash insurance in place.

9) How should investors use CAOS in a portfolio?

As a satellite hedge or part of an alternatives/diversifiers sleeve, often paired with trend-following managed futures (to address long, grinding drawdowns) while CAOS targets fast crash protection.

10) Where might funding for CAOS come from?

Some allocators replace a portion of high-grade/low-credit-risk fixed income (which may be tax-inefficient and not a reliable crash hedge) or carve out from an existing alts bucket.

11) What are the main trade-offs and risks?

  • It will not profit in all down markets—especially gradual drawdowns.

  • Option-market dynamics (volatility, skew, liquidity) affect hedge cost/benefit.

  • Complexity: understanding option carry and convexity requires education.

12) Why consider CAOS versus a basic 60/40?

When stocks and bonds fall together, a classic 60/40 can struggle. CAOS adds an explicit, convex hedge intended to limit tail-risk damage, with an ETF structure for access, liquidity, and potential tax efficiency.

3. Specific Risks: Leverage, Path Dependence & Tail Risk

Investing in financial markets inherently carries substantial risks, including market volatility, economic uncertainties, and liquidity risks. You must be fully aware that there is always the potential for partial or total loss of your principal investment. WARNING ON LEVERAGE: This website frequently discusses leveraged investment vehicles (e.g., 2x or 3x ETFs). The use of leverage significantly increases risk exposure. Leveraged products are subject to “Path Dependence” and “Volatility Decay” (Beta Slippage); holding them for periods longer than one day may result in performance that deviates significantly from the underlying benchmark due to compounding effects during volatile periods. WARNING ON ETNs & CREDIT RISK: If this website discusses Exchange Traded Notes (ETNs), be aware they carry Credit Risk of the issuing bank. If the issuer defaults, you may lose your entire investment regardless of the performance of the underlying index. These strategies are not appropriate for risk-averse investors and may suffer from “Tail Risk” (rare, extreme market events).
