In the wake of the financial crisis, investors are increasingly concerned with ways to mitigate extreme losses. We analyze various approaches to enhancing traditional portfolio construction with tail-risk control. Interestingly, we find investors have better managed tail-risk using a minimum-volatility overlay strategy than explicitly penalizing extreme losses via conditional value-at-risk (CVaR). From a practical perspective, this solution can be cheap and easy to implement because it will not result in a rebalancing of the fund, and various minimum-volatility products are readily available on the market.
