In the event of the loss, however, the insurance buyer can expect to be paid much more than the annual cost of the insurance. Unfortunately, we cannot currently say the same thing about insuring a stock portfolio against a major loss. For instance, it would cost nearly 4 percent in premium to buy a put option that starts to pay off after the market falls 15 percent over a one-year period. Because of this high cost, the option would lose money until the market fell by 19 percent. And even if the market falls further and the option pays off, the return on premium will be much lower than in the example of general insurance.

Why you canât hedge tail risk
"
The number of US-based institutional investors that investigated (and continue to investigate) tail-risk hedging is absolutely massive. Having very recently left a role as a derivatives specialists (listed index option-based strategies) at a $300B asset management group I can assure you that the number of accounts that we ran some form of tail-risk overlay for become substantial. Yes, the dedicated collateral to those overlays in tiny because of the efficiency of the margin requirements attached to listed index options, but the notional values they are structured to protect are substantial, and growing.
There is no such thing as a cheap put, true, and that is what many misguided clients came to us looking for. Still, the idea that the industry hasnât evolved to the point where large asset allocators are now sophisticated enough to evaluate and implement option-based hedging approaches just isnât correct. From targeted volatility funds to using options spreads like collars, put-spread collars, and condors to fund long put positions. These strategies have real and growing traction.
