Eh, the article makes it out to be more of a directional bet this is. Here's IMO the most pertinent bit:
Tail risk funds like Universa generally suggest that investors put 1% of what they put into stocks into these hedges. A fund that spends $100 million on equities would put about $1 million to $1.5 million into a tail-risk strategy.
It's a form of diversification, hedging your portfolio against a very unlikely negative outcome. 99% of your portfolio will perform well in a strong market and poorly in a down market, so you offset this and effectively narrow the range of possible outcomes by making a very small bet that is most likely going to be a loss, but will post big profits if the rest of your portfolio does badly.
For an individual investor, put options are probably the best analogy - if you have $16,533 in a S&P500 mutual fund (this being about the price of a 100-share block of the SPY exchange traded fund), then you could buy a deeply-out-of-the money put option on the underlying ETF fund. To protect against a 20% drop, you'd want a strike price of around $135 or so. This would give you the right, but not the obligation, to sell 100 shares of the SPY ETF at $135 a share on or before a specified point in the future. Why would you want to do that, with a current price of $165? You wouldn't, really, and you most likely never will. But if you buy the option to do so now, it's cheap (for example, a put with a December 20th, 2014 expiration date and a strike price of $135 can be bought for $6.32 a share, or a 100-share contract of $632 plus commission. That's a very long option contract - an Aug 17th '13 contract is a bit more typical, and is $0.31 a share). If suddenly something happens and the economy crashes, and the SPY ETF suddenly drops down to $115 or so (a loss of 30%, tame compared to '2008 but a "black swan" event by most definitions and not a likely occurance) then the option to sell 100 shares of the SPY ETF at $135 a share is suddenly tremendously valuable - in fact, worth $20 a share or $2,000 all in for something that you bought for $600. What this does is effectively cap your losses - your ETF investment losses will be offset by gains on the option, so no matter how far the market crashes, your portfolio won't decline below $13,500, and your loss would be capped at about $3,600 - the $600 option premium plus about a $3,000 depreciation from today's price to the strike price.
That's sort of how a "tail risk" fund functions in a broader portfolio - people very rarely invest in them because they expect the market to dive. Rather, the idea is that it's a good diversification move because the payoff should be negatively correlated with the rest of your portfolio.
Also, I love options. Clearly. :lol: asymmetrical payoffs kick ass, imo.
