Viking Analytics: Weekly Gamma Band Update 5/23/2022

By Erik Lytikainen | May 23, 2022

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 S&P 500 (SPX) attempted to rally last week and was rejected at a key resistance level near 4,100.  While we don’t believe that gamma metrics are the only factor in trading, we do believe it is relevant that the last three rally rejections occurred at one of our key gamma levels. This market is “risk off” until both levels are breached to the upside. Our gamma-band model enters the week with a 0% allocation to the SPX and will remain flat as long as the SPX remains below the lower gamma level, which is currently near 3,980.

One of the primary drivers of gamma trading metrics is the hedging and re-hedging patterns of the options market makers. One of them that is relevant for now is this: when investors buy a put to hedge, the market makers sell the index in order to hedge their long put position.  As a result, the phrase “the market won’t stop falling until investors stop buying puts” has merit.

The Gamma Band model[1] can be viewed as a trend following model that is shows the effectiveness of tracking various “gamma” levels. When the daily price closes below Gamma Flip level, the model will reduce exposure to avoid price volatility and sell-off risk. If the market closes below what we call the “lower gamma level,” the model will reduce the SPX allocation to zero.

The main premise of this model is to maintain high allocations to stocks when risk and corresponding volatility are expected to be low.  For investors who have been conditioned to “buy low and sell high,” it is counter-intuitive to increase allocations when the market rises, but this approach has shown to increase risk-adjusted returns in the back-test.  

Risk management tools like this have become more important than ever to manage the next big drawdown. We incorporate many options-based signals into our daily stock market algorithms. Please visit our website to learn more about our trading and investing tools.

The Gamma Band model is one of several indicators that we publish daily in our SPX Report (click here for a sample report). 

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 show how tail risk can be reduced by following a few simple rules.  The daily Gamma Band model has improved risk-adjusted returns by over 60% 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
