Understanding the S&P 500 VEQTOR Index

It is unfortunate that there are not more mutual funds or ETF’s that directly enhance long equity positions with option overlays. I have covered the enhanced Sharpe ratios (risk-adjusted returns) that often accompany these strategies.  I was surprised to find out that Direxion is going to bring the S&P 500 Dynamic VEQTOR Index to the mainstream retail investor packaged nicely in a simple ETF.  As a follow-up to my readers’ requests when I first described the strategy’s performance, I want to take a closer look at just how the index makes systematic calls on implied volatility and how it has achieved such stellar returns.

The S&P 500 Dynamic VEQTOR Index (Volatility EQuity Target Return) represents an investment in the broad equity market with a dynamically rebalanced volatility allocation.   The strategy gains its volatility overlay through the use of short-term VIX futures.  The premise of the strategy is that the VIX has a correlation with the S&P 500 of about -73%.  When the S&P 500 falls sharply, the VIX spikes and then slowly  reverts to a long-term mean.  Under the simplest strategy, a fixed allocation to VIX futures will reduce the volatility of the long equity portfolio by providing a positive offset when the equity market corrects.  This would increase the risk-adjusted returns of the portfolio by reducing the tails of the portfolio’s return distribution.  If the idea is taken one step further, then we can introduce a tactical allocation in volatility wherein the investor can capture the gains from a volatility spike by reducing the allocation to volatility under the assumption that it will eventually revert to the mean.

The S&P 500 VEQTOR Index has the following characteristics:

  • Daily rebalancing mechanism
  • Dynamic long exposure to equities and implied volatility which are based on the realized volatility trend and environment
  • Stop-loss

In order to determine the implied volatility trend, the index uses the following scheme which requires 10 consecutive daily indicators:

  • Uptrend: 5-day Average Implied Volatility > 20-day Average Implied Volatility
  • Downtrend: 5-day Average Implied Volatility < 20-day Average Implied Volatility
  • No Trend: Neither

With our trends established, we can look at the respective allocations:

*The realized volatility environment is determined using the last 22 trading days.

The last piece of the puzzle is the stop-loss feature.  Every day, the 5-business day performance of the excess return strategy is evaluated.  If there is a loss greater or equal to 2%, both equity and volatility allocations are moved to 100% cash position at the close of the following business day.  The strategy will allocate back into equity and volatility once the 5-business day loss is less than 2%.

After a long-winded explanation – just how did it do?

Not a bad strategy at all...

I challenge you all to use this as a guideline for starting your own long vol / long equity strategy.  I think there is a lot of promise in these types of strategies as tools for individuals and fund managers.
