Nope. No one has.

As you suggested yourself, the reason is that the costs of maintaining the hedge during "normal" markets ends up being more than the benefits during the "tail risk" scenarios.

This true in no small part because the "tail risk" events have an infinite number of possible causes, so by trying to insure against them you end up being the general who is always fighting the last war.

This is not true. There are firms implementing these type of strategies. I was wondering if some BH's have been aproached by these firms and be able to see at least some historical real life results postive or negative.
The world is full of salesmen, and their job is to sell.

You asked if there is real-world evidence that tail risk prevention strategies "work", and I'm telling you that there isn't any. Not on balance, and not with replicability.

This would lead to lower absolute returns over the long term if it was a strategy you used continuously, ie, buy out of the money puts and continously roll them over throughout your life. The only way it would be more profitable is if you were fairly confident about a market peak at a given point of time and bought the puts, then the market agreed with you and tanked or if your investment horizon was short (you are old), you were worried about protecting principal but don't want to sell (perhaps so you don't realize a taxable gain on the underlying stock while working, want to delay until you have lower retirement income) and a huge crash occurred not long after buying the puts. Not continuously over a long horizon. If you look at how options are priced anyway, you are normally better off writing them than buying them for a long run strategy. The probability of far out of the money puts ever being profitable is low, they have no intrinsic value, you have volatility to deal with, time decay will be working against you, and the market has a positive skew. Due to the skew and option pricing, I'd be more likely to write out of the money puts than buy them as part of a long term strategy. If you did want to buy puts anyway you would buy leaps on spy or qqq and roll them over periodically to counteract the positive market skew and time decay.

The two ETFs you mention don't offer real tail risk protection, although TAIL comes closest. TAIL looks like a guaranteed way to go to zero over time but you're also paying them to hold treasuries as well. HTUS is a long-short ETF that uses some sort of proprietary model to decide whether to be long or short. If their model failed and they were long when they should have been short then how would this offer tail risk protection? It's an ETF that whose management goes back and forth on whether they should be a leveraged or an inverse ETF. I don't think their predictive power is any better than the next investor's so I would be unlikely to park any money with them. If you wanted to implement an out of the money put strategy you should do it yourself to cut out the management fees. Get an account at tastyworks, use an option screener to pick the leap you're interested in, and then buy it yourself.

No, it’s not a good strategy any more because the risk of crashes/black swans is now priced into those out of the money puts, and they’re very expensive, on the order of 1.5-2%+. Worse still, you’re only rewarded for the risk if the actual volatility exceeds the priced in implied volatility. Even without that, it’s only occasionally a good strategy (in times of a true bubble) that can still lose you lots of money along the way in a time and way that’s particularly irritating to our instincts: losing money persistently during bull market runups.

Given human behavior, there will likely come a time or bubble where these options are ridiculously cheap and wouldn’t provide this degree of problem, but the Big Short scenario of paying .5% to buy fire insurance on a burning explosives factory is unlikely to be repeated anytime soon.

The Boglehead way of tail risk protection:

Rick Ferri uses a lower % of more volatile equities (small cap value equity fund/ETF) and more bonds vs a higher % of less volatile equities (TSM) and less bonds (TBM).

E.g. 40% SCV + 60% TBM vs 60% TSM + 40% TBM.

Ah, the old harvesting nickels in front of a steamroller strategy. That’s how people blow up. And actually, this is not too dissimilar from the line of thinking that cost a lot of “clever” volatility sellers their whole nut back in February. What could go wrong, right?

If you want to sell puts, please keep them near the money - that way you know the score and aren’t caught like a deer in the headlights by the “once in a hundred year” event that seems to happen about once every five years now.

Additionally, it is near the money puts, not far OOM, that tend to be overpriced. People are willing to pay up to protect themselves from a small loss that they consider likely, less willing to pay up to protect themselves from a large loss they see as remote. So if you are selling the equivalent of insurance, sell policies on door dings, not tsunamis.

hdas wrote: Wed Aug 08, 2018 9:52 am Hi All,
I have a very specific question: Has anybody seen evidence (real track record) that tail risk strategies work?

Context:
- The most interesting type of strategy involves using part of your portfolio to buy 'insurance' in the form of long out of the money options that would explode in value if a deep correction happens. The interesting part (see video linked) is that said insurance allows you leverage your equity portion.
- I'm really curious to see how this has performed overtime, specially considering that really bad events don't happen very often. However we do have sporadic episodes of exploding volatility (2011, Aug 2015, Feb 2018)
- One likely scenario is that when its said and done, the cost of the insurance + the manager fees erode most of the added value.

Video Explanation: https://youtu.be/LyGtiiGBEc8

Finally, here is a chart https://yhoo.it/2OQoz1b of YTD with the performance of VTI (Total Stock Market ETF), TAIL (Meb Faber Cambria product for tail protection ETF) and (HTUS - Blair Hull tactical allocation ETF). We can see that these particular implementations fail to really do well in times of stress (here comparing performance during the recent correction, not ytd)

Cheers, :greedy

Note:

I don't know much about these hedge products... but the video explanation looks to be like a simple, slick video graphic of how they want you to view what they do, with no factual information. No better than a late night tv ad my Alex Trebek selling life insurance with no physical required, guaranteed to accept your application.

Anything of that nature strikes me as something to stay away from, unless I can find accolades about the idea or product by smart people with no agenda, nothing to earn by the sale of that product. No reason to think their graphic has anything to do with facts.

Help Understanding Mark Spitznagel And Tail-risk Hedging?

Post by bmstrong »

[Thread merged into here, see below. --admin LadyGeek]

https://www.worth.com/the-goat-whisperer/

I'm enjoy reading about strategies people use in Investing. (You never know if something might be useful down the road.) I initially found Spitznagel through Taleb, whom I enjoy, but can only take in small doses. Everything Mark says just remains obtuse, deliberately?, and I don't think I've ever read anything that reveals his actual positions.

Can anyone give me a [(removed) --admin LadyGeek] FAQ on tail hedging?

Some notes:

1. Only the shadow knows what is truly hidden behind those notes and disclosures in the final part of the report.
2. Results skewed by 2008 crisis, but OTOH that's when you want a fund like this to work.
3. Unless one sits closer to the fire to scrutinize the data, it's hard to draw any conclusions.

Here's a general comparative of diff risk mitigation strategies:
Here's a blog piece from a couple of years ago with more specifics what Universa does, or did, or was doing in general at least as gleaned from examples in Spitznagel's (the CIO/quant behind this fund though Taleb helps market it) articles and books:
https://thefelderreport.com/2016/08/15/ ... portfolio/

I agree at least with the second part of a previous comment "+ the manager fees erode most of the added value" If an idea is generally valid, it's not so likely you come out ahead doing the exact proprietary strategy and paying the fees, as opposed to doing the simplified version in the manager's books and articles by yourself. And a brief search showed Universa having a $25mil minimum investment* as of some years ago so it's probably academic for most.

The simple version of the strategy in simplest terms seems to be, buying 2+ month maturity puts on the S&P, struck 30-35% below of the money, then selling and rolling into the next set of options after a month. There's also an idea of doing this only when the market is highly valued according to the Tobin Q.

*although they define investment a little differently than usual. That means you want them to hedge at least $25mil of stock portfolio, you only give them a small % of that to buy the hedges. Anyway still hardly a retail product, and I guess it's still not even if the $25mil figure has been lowered, Universa's website gives no such details, hardly any info at all.

I've spent a lot of time looking at this. I've even tried it out, small dollars on puts.

It should work in theory. However, in my trials, the market was going up and I just found the whole thing tedious.

As today's preeminent doomsday investor Mark Spitznagel describes his Daoist and roundabout investmentapproach, “one gains by losing and loses by gaining.”This is Austrian Investing, an archetypal, counterintuitive,and proven approach, gleaned from the 150-year-old Austrian School of economics, that is both timeless and exceedingly timely.

In The Dao of Capital, hedge fund manager and tail-hedging pioneer Mark Spitznagel—with one of the topreturns on capital of the financial crisis, as well as over acareer—takes us on a gripping, circuitous journey from theChicago trading pits, over the coniferous boreal forests andcanonical strategists from Warring States China to NapoleonicEurope to burgeoning industrial America, to the great economicthinkers of late 19th century Austria. We arrive at his centralinvestment methodology of Austrian Investing, where victorycomes not from waging the immediate decisive battle, but ratherfrom the roundabout approach of seeking the intermediatepositional advantage (what he calls shi), of aiming at theindirect means rather than directly at the ends. The monumentalchallenge is in seeing time differently, in a whole newintertemporal dimension, one that is so contrary to ourwiring.

Spitznagel is the first to condense the theories of Ludwig vonMises and his Austrian School of economics into a cohesiveand—as Spitznagel has shown—highly effective investmentmethodology. From identifying the monetary distortions andnon-randomness of stock market routs (Spitznagel's bread andbutter) to scorned highly-productive assets, in Ron Paul's wordsfrom the foreword, Spitznagel “brings Austrian economics fromthe ivory tower to the investment portfolio.”

The Dao of Capital provides a rare and accessible lookthrough the lens of one of today's great investors to discover aprofound harmony with the market process—a harmony that is soessential today.

The Meb Faber thing seems to be talking about buying 5% out of the money puts. The thing I linked, in turn linking to an article by Spitznagel is talking 30-35% OTM puts. Seems like fairly different strategies.

It's funny the Universa site stuff never mentions the term 'put option'. It's likewise with blurbs about Spitznagel and 'Austrian economics'. I'm puzzled what that has actually has to do with anything. Maybe I'm too simplistic. Which index put buying strategy yields which historical result? :D (directed at Universa).

I'm also still interested in the part where I linked about only doing this when the market is in the top quartile of historic Tobin Q. Measures like that (CAPE etc) have been historically high the whole time this fund has existed. I wonder if the idea is really for the fund to sit on its hands when/if the Tobin Q isn't historically high (setting aside debate on whether measures like that can be directly compared between era's). It specifically says though that constant put buying in expensive and cheap stock markets doesn't work in general. And that's the conventional wisdom, that it does *not* work because of the risk premium of the volatility skew (higher implied volatility for lower strike options). Because there's no 'natural' home for short positions in low strike stock index options with any end user. The people constantly short those options are delta hedgers who need a significant positive expected return 'picking up nickels' hedging those options out to a profit in normal times (because they sold them at generally implied volatility than subsequently realized volatility) v. getting 'run over by steamrollers' every once in a while when realized volatility spikes to where nobody can act fast enough to avoid being seriously burned by the negative convexity of being short those options. And Universa is generally willing it seems to mention the term 'positive convexity' for being long those options, even in some 'explanations' of that they do, with options apparently, which don't ever use the word 'option'. :D

It's mentioned in the article.

You buy deep out of the money puts for pennies. If the market crashes you make dollars on your pennies. But since the market goes up 2/3rds of the time, 2/3rds of the time you lose money.

That's the opposite of what I'd expect to work best. High risk/return assets in general tend to be overpriced due to investors with limited access to leverage seeking extra returns. If you're already at a point where you want less risk than 100% total stock market, you're likely better off adding in a minimum volatility fund instead of doing a small-cap-value / treasury barbell strategy.

It’s a Swedroe approach, not a Ferri one.

One justification is that small Value stocks tend to have a lot of internal leverage, and if you plot them vs the 500 at 1.5x -50% cash, you get similar results overall both in return and standard deviation.

Quotes from the article in Alpha Architect by Aaron Brask on strategies to achieve tail risk protection.
TRH strategies are very complex and will often end up with polarized results. As highlighted in the disclaimer above, it is important to understand these strategies are speculative in nature.
Accordingly, I believe it is important for investors to understand the challenges involved with these strategies before executing them. Even then, I recommend limiting allocations to these strategies. In general, I would allocate no more than 5% of one’s overall portfolio or 10% of one’s equity allocation to TRH strategies.
Not exactly a ringing endorsement.

Well, to be fair the kind of TRH he's describing has a significant insurance premium and a downright breathtaking upside. It's a far greater diversifier in terms of effect on returns in bad times than just about anything else out there, but that's why there's a volatility risk premium that's a real beating.

Artemis capital management is one of the good funds in this space based on the conversation with some friends.

I have not invested, but i find their market views and research interesting.
http://www.artemiscm.com/welcome#research

Their Vega fund started in 2012, I could find investor letter 2016 in their website. This is their track record.
Image

Personally I roll my own option backspreads (1x2 or 1x3s) which has compensated me during Feb and recent turmoils.

From my experience, It is hard to invest in these tail strategies because of the drag. One needs to be tactical about it. If you can find some kind of regime switches to trigger these tail strategies, then I find it useful.

There are several regime switches like Bloomberg risk index, HSBC RiskOnRiskOff (RORO). These are all based on combination of vol and returns of many asset classes, Liquidity index like TED spread etc. Or you can construct your own based on risk assets invested and own risk tolerences

Here is the video of Chris Cole discussing vol.

VXX is an ETN that tracks a strategy of owning VIX futures that are 1 or 2 months from expiration. From Jan 2010 on, it has had a CAGR of -52%, but if you ask Portfolio Visualizer to minimize volatility subject to an 8% target return over that period, it gives weights of

58.09% SPY
38.42% TLT
3.49% VXX

Results are here.

"Portfolio optimization results with goal to minimize maximum drawdown subject to subject to 8.00% targeted annual return" give similar weights. Doing an optimization to "minimize conditional value-at-risk" gives VXX weight of 9.09%.

In most years you can sell your VXX position and realize capital losses. On the rare occasions that you realize gains in VXX you may have some stock market losses that you can harvest to offset the gains. The simulations above assume monthly rebalancing. I wonder if people will have patience to reload positions in a wasting asset such as VXX, month after month, to protect against the occasional stock market dive.

Rather underwhelming given the year we had. Thanks. :greedy
His fund's mandate is pretty clear. His investment strategy intended to be an insurance policy on the market without paying too much for the policy. It works mostly on high volatility and high volatility trend markets. Last year we had burst of high volatility and petered off immediately. He doesn't monetize during those bursts and results reflect that. He is within the mandate of the fund, where investor expecting protection during 30 to 40% down market.

Some comments after reading this thread. Hope I can shed a little light on this space, while attempting to stay brief and not too in the weeds.
* Note that a tail hedge strategy is different than a volatility fund that is structurally long Vega (like Artemis, I believe).

Q: Why use a tail hedge manager when it's a negative EV strategy (and has fees to boot)?
A: It has to be assessed in the context of the total portfolio. Tail strategies are not capital intensive, which allows the investor to use more balance sheet to invest in higher returning assets. Therefore, you can get to a point where a portfolios expected return can be comparable with or without the tail hedge drag. (There isn't agreement on using these strategies across top endowments+foundations by any means.)

Q: If an endowment hires a tail hedge manager, what is the goal/strategy?
A: Generally the mandate is bespoke, with the endowment giving the manager a mandate. So basically it's a balancing act between how much % of total portfolio you are willing to actually hand over, the annual budget (certain costs related to the premiums only), and the endowment tells the tail manager, for example, I want to tail to "attach" or begin making money once equity markets are down 10% and I expect to profit by xx% if the equity market goes down 25%. Finally, the endowment needs to tell the tail manager how they expect them to monetize gains on the back-end

Picking a good manager is critical because you want someone who knows how to:
- Hedge the risk you want hedged (minimizing what's called basis risk)
- Minimize the cost of the hedges (the best managers are not doing rules-based systematic put buying in some naive way)
- There is some active management needed because the budget you agree to spend per year only pertains to the premiums paid for the instruments. - - Keep in mind that is only part of the equation, as the strategy can also generate PnL from changes in implied (and realized) volatilities. The reason for the gains/losses are in addition to negative carry is because these managers are attempting to generate returns (or minimize the cost) while structuring as much positive convexity on the tails

*Final note would be to read Universa and other managers performance in this space with a grain of salt. Most actual tail programs are custom to the client. Some groups - that may or may not have been discussed in this thread - tend to play games with their track record. Not hard to cherry pick one return stream that happens to look good, but who knows what the mandate was. Also, they might play funny games with the fact that they are managing a notional exposure based on the clients actual portfolio, but that's very different than a $ figure like the AUM of a fund. Finally, tail hedge groups will back-test. Worse, the may show "real performance" but not account for the fact that none of the gains were locked in (so there is a lot of hiding the challenges with execution during the monetizing of profits).

Happy to share more if there are direct questions I missed

The problem is that OTM put options are usually very expensive.

To illustrate, current price of 1 year protection:
SPX Put @ 2225 Nov 20, 2020, last price 31.40

This would limit your loss to 30% (as (2225-31.40)/3120 )
Annual cost is 1% (as 31.40/3120)

If SP500 crashes to half value, you make 20x on options. If you allocated 2.5% of your stocks to protection, this mitigated all of your stock loss.

The problem is that most likely, this kind of crash won't happen and you'll keep wasting 2.5% of your portfolio every year.

Related article. Summary:
Put options are supposed to be a hedging instrument against a market crash.

However, they are systematically overpriced and, in the long run, does not do their hedging job well.

There is no optimal strikes and time to expiration that would make put options an efficient hedge in the last 25-year period (including two severe bear markets).

The only way to efficiently use puts to protect a portfolio is to forecast somehow the approaching recession and the respective bear market and adjust the hedging strikes accordingly.

I recall reading in the mid-nineties that the Getty foundation directors were convinced the SP 500 was about to dump so they bought portfolio insurance. That resulted in a 500 M loss when the market went against them.

That was my thought. Generally speaking, people will pay above expected value for insurance and for lottery payouts.

As I recall, Taleb (Black Swan guy) recommends going long volatility because people supposedly underestimate big movements/"black swans." But the observed "volatility smile" in options markets would seem to suggest the opposite.

How would you deal with counterparty bankruptcy risk on portfolio insurance? Maybe split it up with multiple counterparties?

An interesting question is: which approach loses more portfolio value over the long term, the increased costs of strategies for tail risk protection or the cumulative losses from tail risk itself? I suspect that the answer is highly period dependent depending on the chosen dates of backtesting. I also suspect that in general over most time periods more money is lost in fees and costs for complex tail risk protection strategies preparing for tail risk than by the effects of tail risk itself. One basic problem with tail risk protection is that you cannot anticipate where the next black swan or market crisis is coming from. Hyperinflation protection requires very different protective countermeasures than the Great Depression. Wars/massive natural disasters including climate change may require totally different protections. Funding all these protections as well as an advisor to choose the correct ones in the correct proportions is almost certainly going to be a drag on long term portfolio returns in the absence of severe problems. And even with severe problems you face the question of whether your approach actually works when it's needed with the modest allocation that is applied in that direction in your portfolio. I'm not a fan of complex and expensive strategies for volatility or tail risk protection over and above a solid balanced portfolio, but that's just a personal opinion. Others may rationally see it differently.

I like this part. It warns of two kinds of BH complacency; long-only equities & fine tuning risk by owning more bonds.
If or when there is another crisis, conflicting economic interests between generations will rapidly emerge. Baby Boomers (23% of the population; 56-74 years old) are wealthy and nearing retirement with incentives to support policies that bail-out asset markets, but maintain the purchasing power of their savings. Millennials (26% of the population; 24-39 years old), will likely be the first U.S. generation to be worse off economically than their parents and have reason to support inflationary policies that redistribute capital directly to people but destroy debt. Any slowdown in secular growth could cause fissures in the social fabric with unpredictable ramifications.

Very interesting article on asset allocation and it's nudged me to own a little more gold. The Trinity Portfolio approach of Meb Faber is similar. I have seen Chris Cole interviewed before and it's unusual for very smart / quant-orientated investors like him to be so open-minded toward gold (19% of the example balanced risk portfolio).

Food for thought: a tail risk hedge should always be tailored and specific.

A generalist hedge (S&P 500 puts for an ordinary investor with no specialized exposure) will have the drag of insurance and only be a matter of luck whether the payoffs outweigh the cost drag. The risks being targeted tend toward the speculative, negative black swan type events and

A specific tail hedge (though it’s not strictly a tail) I have in mind that’s got very specific triggers would be investing in oil futures by a long-haul trucker. An energy crisis is foreseeable, has precedents, and has clear-cut economic consequences.

It’s very hard to impossible to find one hedge that perfectly hits all four of Bill Bernstein’s Deep Risks.
