If uncertainty is the bane of investors everywhere, then the fear of large losses in a bear market is the boogeyman hiding in the closet. The threat of an agonizing downturn often leads investors to carry lower equity weights in their balanced portfolios than might be advisable, and even drives them to hold excess cash to avoid the risk of sizable declines.

ETF families have responded to this anxiety with a fund design that takes some downside risk off the table and may enable investors to tiptoe into equities even when they suspect a selloff might be around the corner. Known as “buffer”, “defined outcome”, or “target outcome” funds, these ETFs utilize an options collar overlay to trim the upside and downside tails of the underlying asset’s return distribution, thereby giving nervous investors a more comfortable way to pick up some equity exposure during riskier times.
