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.
The S&P 500 (SPX) enjoyed a big relief rally Tuesday through Friday, closing near the highs each day, and just below last week’s and the end-of-week gamma flip level. We are entering this week with a 50% allocation to the SPX. War and related headlines will likely continue to whipsaw the market. If value rises above the gamma flip level (currently near 4,490), our model will flip to a full long position.
Last Friday was an important quarterly option expiration, which can be associated with up/down volatility before and after the expiration. There are order flow dynamics that can help to explain these patterns. The dashed lines below show the dates of the recent monthly expirations.
The Gamma Band model 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.

 The Gamma Band model in our SPX Market Report adjusts position size DAILY based upon the daily closing levels of SPX value and calculated Gamma Neutral. The Weekly Gamma Band model is shown for illustrative purposes only.
