Spitznagel's Universa Investments fund's massive COVID-19 gains were revealed in a letter to clients that was leaked and seen by Business Insider. In the letter, Spitznagel highlighted the gains the fund had achieved through its tail-risk hedging strategy, while the broader markets and indexes suffered sharp declines. 

What Is Tail-Risk Hedging? 

Tail risk refers to the risk of extreme events occurring at the far ends, or tails, of a probability distribution. Tail-risk hedging is an investment strategy that aims to protect portfolios from extreme market downturns and frequently use a combination of financial instruments and strategies. 

It is common for a tail-risk hedging strategy to use put options, credit default swaps, Volatility index futures, U.S. Treasuries or a combination of any of the above. 

Investors can find convenient exposure to a tail-risk hedge through the Cambria Tail Risk ETF TAIL which holds a portfolio of out-of-the-money put options on the S&P 500 Index, as well as U.S. Treasuries in order to mitigate risk. 

The ProShares Trust Ultra VIX Short-Term Futures ETF UVXY provides 1.5x leveraged exposure to the daily performance of the S&P 500 VIX Short-Term Futures Index and can also be part of a tail-risk hedging strategy.
