Retail Tail-Risk Hedging: Put Costs, Convexity, and Strategy Design

Article Quant Q&A · Author: slava-kohut
Read the original

Summary

The document considers whether retail investors can hedge severe equity-market declines by buying deep out-of-the-money index puts, how to size and roll such positions, and whether a packaged product may be easier to use. The replies caution that repeatedly purchasing puts can impose a substantial ongoing cost and reduce expected portfolio returns. They distinguish a simple put overlay from more complex tail-risk approaches that may combine index and volatility options, dynamic hedging, and other sources of carry or income.

One reply describes a possible ETF options overlay designed to add convexity, while another mentions butterfly structures that sell options nearer the center of the distribution and buy the wings. These are brief descriptions, not a sizing or rotation framework, and the document supplies no performance data or allocation rules. It therefore outlines design trade-offs without establishing that any cited product or strategy will deliver a particular hedge or return.

Key ideas

  • Buying deep out-of-the-money puts can provide downside convexity but may steadily erode portfolio returns.
  • More elaborate tail strategies may combine index options, volatility exposure, dynamic hedging, or carry sources.
  • Butterfly structures can sell options nearer the center while buying more distant wings.
  • The discussion gives no method for sizing, rolling, or allocating to a retail hedge.

# Simple strategies for tail risk hedging that retail investors can use


# Simple strategies for tail risk hedging that retail investors can use












Universa Investments run by Mark Spitznagel popularized the idea of portfolio insurance (also known as tail hedge) protecting the investor against severe market declines (tail risks). By using this tail hedge, the investor can increase their share in riskier assets (stocks) while bringing the total risk of the portfolio down.

In my understanding, a retail investor can implement a tail-hedging strategy by purchasing deep OTM SPY puts. How exactly is this achieved? How to estimate the number of puts and how to rotate them? How much of capital should be allocated to this tail-hedging strategy? Or maybe it is easier to purchase a ready-to-use solution (e.g., ETF)?

Thanks in advance for your help. The question was intended to be broad.

I'd echo @noob2 and add https://www.ivoletf.com/ for rates related vol/inflation hedge.

I think at some point there will be some ANT (active non-transparent) ETFs running a strategy similar to tail risk hedging. Paul Kim has recently filed downside/upside convexity ETFs, which may become more relevant in the future. As evidenced:

> The option overlay is intended to add convexity to the Fund. If the market goes up, the Fund’s returns may outperform the market because the adviser will sell or exercise the call options. If the market goes down, the Fund’s returns may fall less than the market because the adviser will sell or exercise the put options. The adviser selects options based upon its evaluation of relative value based on cost, strike price and maturity.

Just buying deep out of the money puts would technically be a tail risk hedge, but you won't get returns anywhere near those from Universa. Simply buying put option is too expensive and you will erode portfolio expected return over time. They do use options on the index, but also on volatility (the Vix, etc.) to get the convexity you want. But, in addition to the convexity component they also have carry stategies (selling call options, currency carry, momentum strategies, etc.) designed to consistently bring in income to help offset the cost of convexity. The combination of strategies is what makes the product, not just buying put options.

Universa sells lots of butterflies (shorts in the body of the distribution) and buys wings to construct a tail strategy. add in dynamic hedging and you have the basics of the strategy.

Fat tails = more quiet times and make 99% of days in the markets irrelevant. So the body of the distribution can be sold.
