We share the Weekly Gamma Bands Update by Viking Analytics. The report uses options gamma to help you better manage risk and your equity allocations.

Gamma Band Update

The Gamma Band weekly model[1] is at a full allocation to the S&P 500 (SPX) last week through the important quarterly option expiration.  When the daily price closes below the Gamma Neutral or “Gamma Flip” level (currently near 3,910), the model will reduce exposure in order to avoid price volatility. If the market closes on a daily basis below the lower gamma level (currently near 3,710), the model will reduce the SPX allocation to zero.

The Gamma Band model can be appropriate for investors who want upside exposure to the stock market, while protecting against downside tail risk.  For investors who have been conditioned to “buy low and sell high,” it might seem counter-intuitive to increase allocations when the market rises, but this approach has shown to increase risk-adjusted returns in the back-test.

This is one of several signals that we publish daily in our SPX Report. Overall, we would rate the SPX options market as “cautiously bullish.”  A free sample of the SPX report can be downloaded from this link.  Please visit our website to learn more about our daily reports and price signals.

The Gamma Flip – Background

Many market analysts have noted that daily volatility in the S&P 500 will change when the value of the SPX moves from one gamma regime to another.   Some analysts call this level the “gamma flip.”  The scatterplot below shows how price volatility (on the y-axis) is increasingly lower as the value of SPX rises higher above the Gamma Neutral level (on the right side of the chart).  When the value of the S&P closes lower than Gamma Neutral (to the left of the chart), volatility increases.

Gamma Band Model – Background

The purpose of the Gamma Band model is to reduce tail risk.  The daily Gamma Band model has improved risk-adjusted returns by 70% since 2007.  The graph below demonstrates how this approach can limit drawdowns while maintaining good returns.  A quick video introduction of the Gamma Band model can be seen by following this link
