Hedging Tail Dangers: The Tortoise Versus the Hare

2022 was a troublesome yr for traders, as each shares and bonds endured extended drawdowns not seen in current a long time.

What, if any, classes ought to traders take from the market’s efficiency in 2022? To assist reply that query, of their December 2022 paper “Ought to Your Portfolio Safety Work Quick or Sluggish?,” the Portfolio Options Group (PSG) at AQR examined the efficiency of three tail-risk hedging methods:

The paper begins by observing: “If you already know a drawdown goes to be short-lived, then it’s most likely not going to impair your skill to satisfy your longer-term aims. Then again, this additionally suggests an vital, but delicate fact: in relation to wealth creation, investments that carry out higher in longer-lived drawdowns could also be extra priceless than ones that carry out higher in sharp crashes. Extra pointedly, portfolio safety methods that work finest over shorter-term ‘tails’ usually are not as priceless as methods that may ship over longer ones.”

AQR then examined the efficiency of the three methods protecting the 2 massive drawdowns skilled over the interval January 2020-September 30, 2022 (which remains to be ongoing). As seen within the chart beneath, whereas within the short-lived COVID-related drawdown of February-March 2020, the tail-hedging and put-buying methods carried out finest; within the current, longer drawdown that started in January 2022, trend-following carried out finest. 


The PSG then broadened its “tortoise/hare” comparability to incorporate the 5 largest 60/40 drawdowns since 2000, so as of length. As seen within the exhibit beneath, options-based hedging methods outperformed in shorter drawdowns (left aspect) however have been much less spectacular in longer ones (proper). Pattern-following confirmed roughly the alternative sample, posting its most spectacular returns within the protracted unhealthy instances. The analysis discovered this to be true each through the drawdowns themselves (Panel A) and, importantly, from peak to restoration, or “spherical journey” (Panel B), the place the benefits for trend-following are much more pronounced. The authors noticed: “This ‘round-trip benefit’ is smart economically: the worth of safety from choices will increase amid drawdowns (e.g., through increased premiums), leading to greater-than-typical losses within the recoveries that comply with. For trend-following there isn’t any such mechanical hyperlink, and whereas they could battle across the turning level, they’ve a capability to take part in recoveries. In different phrases, trend-following methods could also be anticipated to carry on to (and even add to) their ‘drawdown features’ higher than options-based methods.”


The researchers subsequent examined the impression of common returns exterior of particular drawdown episodes. Exhibit 3 beneath plots long-term cumulative returns for options-based and trend-following methods for the reason that inception of the SocGen Pattern-Following Index (Panel A) 2000 and the EurekaHedge Tail Danger Index (Panel B) 2008. In change for crash safety, options-based methods suffered adverse long-term common returns, whereas trend-following—past its tendency to ship in longer-term drawdowns—produced constructive common returns.


These findings led the PSG to conclude that the tendency for getting places to supply adverse long-term returns “makes them a poor portfolio addition basically, and so they typically see rising costs (through increased premiums) after durations of market stress—making these among the many worst instances to speculate. Analysis suggests trend-following methods are a special story. They’ve proven the flexibility to ship over the long run and notably in ‘gradual’ difficult market environments, and—crucially in the present day—do not need a bent to ‘richen’ amid market drawdowns.”

Additional Proof

AQR’s findings are according to these of Campbell R. Harvey, Edward Hoyle, Sandy Rattray, Matthew Sargaison, Dan Taylor and Otto Van Hemert, authors of 2019’s  “The Better of Methods for the Worst of Instances: Can Portfolios be Disaster Proofed?.”  This paper analyzed the efficiency of a number of defensive methods, each lively and passive, between 1985 and 2018, with a selected emphasis on the eight worst drawdowns (the situations the place the S&P 500 fell by greater than 15%) and three U.S. recessions (8% of the total interval). The authors discovered that essentially the most dependable defensive device, repeatedly holding short-dated S&P 500 put choices, was additionally the most costly technique (-7.4% return over all durations). Whereas it carried out properly throughout crashes (incomes a 42.4% return on common), it was expensive through the “regular” instances (dropping 14.2% on common), which constituted 86% of the pattern, and expansionary (non-recession) instances, which constituted 93% of the observations. As such, passive possibility safety appears too costly to be a viable disaster hedge. The authors famous that choices are additionally costly to commerce; thus, returns would have been even worse after implementation prices.

The PSG’s findings are additionally according to these of Roni Israelov, writer of the research “Pathetic Safety: The Elusive Advantages of Protecting Places,” which appeared within the winter 2019 subject of The Journal of Various Investments. He examined the drawdown traits of systematically protected portfolios utilizing the CBOE S&P 500 5% Put Safety Index, in addition to Monte Carlo simulations, and concluded: “Put choices are fairly ineffective at lowering drawdowns versus the easy different of statically lowering publicity to the underlying asset.”

Investor Takeaways

As with all portfolio selections, an allocation to risk-mitigating methods needs to be a strategic (not tactical) choice. Sadly, many traders succumb to the stress of market turndowns and switch to purchasing places—regardless of the long-term proof that doing so is more likely to be a dropping proposition. As a substitute, traders involved with the chance of extreme, extended drawdowns ought to undertake approaches which can be extra more likely to enable them to realize their targets. Methods so simple as lowering fairness publicity to a extra acceptable degree. Alternatively, traders might add trend-following methods and/or publicity to distinctive sources of threat, comparable to long-short, market-neutral issue methods, which analysis—together with the 2018 research “Tail Habits in Portfolio Optimization for Fairness Type Elements,” the 2021 research “The Finest Methods for Inflationary Instances and the 2022 research “Investing in Deflation, Inflation, and Stagflation Regimes—has proven present diversification and tail-risk hedging advantages.
