Dynamic Hedging and VIX

Dynamic Hedging and VIX

In our video, Confusion with Diversification (click here to view), I introduced the concept of using VIX to dynamically hedge a portfolio, which raised a number of questions. I hope to address many of these questions here.

A central doctrine of financial advice is to concentrate on long-term goals, pick an asset allocation strategy to meet those goals, and stick with it. This approach is defined by strategic asset allocation and calls for setting target allocations, then periodically rebalancing the portfolio back to those targets as investment returns cause a drift from the original allocation percentages. The strategy is often referred to as “buy and hold,” rather than an active trading approach. Of course, the targets may change over time as the goals and needs change, and as the time horizon for major events (e.g. retirement and college funding) grows shorter. Practitioners of this strategy believe that trading in and out of positions in response to daily market gyrations increases costs, reduces returns, and is almost guaranteed to undermine an investor’s long-term objectives.

Market timing, on the other hand, is moving in an out of asset classes in an attempt to profit from the future direction of the market. In a truly efficient market, profiting from these trades would not be possible; however, many investors do not accept this hypothesis and believe that inefficiencies in the market persist and can be exploited. Although numerous academics believe it is impossible to time the market, most active traders believe strongly in market timing. What we know for certain is that it is very difficult to be continuously successful at market timing over the long run.

While these two strategies represent extremes in financial theory and appear to be at odds, a combination of the two may be beneficial. During periods of heightened market risk, earmarking a portion of the portfolio to take advantage of big market moves may help lower volatility. This more active approach is called dynamic hedging. It should be viewed as a tactical asset allocation within a strategic framework.

The most widely watched statistic to measure market risk or volatility is the CBOE Volatility Index, better known as the VIX Index. The VIX Index is designed to measure near-term volatility — as indicated by index option prices — in the S&P 500 Index. Historically, the VIX has moved in the opposite direction of the S&P 500 about 80% of the time. When above its normal range, the VIX indicates a high level of apprehension, and therefore could be regarded as a turning point in the market.

Because of the high negative correlation between the VIX Index and the S&P 500, creating a tactical strategy that reduces portfolio risk when the VIX is elevated is possible and, therefore, could add value to a long-term buy-and-hold strategy. It is also a tactic free of the emotional elements that usually make investing more complicated.
