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 12/28/20

  • The SPX Gamma Band model can be viewed as a long-only trend-following model that reduces exposure when options markets show elevated risk. Since 2007, following this model has similar returns to a long-only position in SPX, albeit with much lower risk exposure.   The Gamma Band model has resulted in a 74% improvement in risk-adjusted return since 2007 measured by the Sharpe Ratio. 
  • The Gamma Band model has maintained a high exposure to the S&P 500 since the U.S. election. The model will generally maintain a 100% allocation as long as the price closes above Gamma Neutral, currently at 3,676.
  • The model will cut the S&P 500 exposure to 0% if the price closes below the lower gamma bound, currently near 3,450.
  • Our binary Smart Money Indicator continues to have a full allocation but could turn cautionary if smart money begins to buy more long-dated puts.
  • SPX skew, which measures the relative cost of puts to calls, shows that the risk appetite of investors continues to be in an average range.
  • We publish several signals each day, ranging from a fast signal in ThorShield to a less active signal (as represented by the Gamma Bands and published in the daily SPX report).  Notably, our daily ThorShield allocation model will significantly reduce equity exposure at today’s close.  A sample copy of all of our reports can be downloaded by visiting our website.

Smart Money Residual Index

This indicator compares “smart money” options buying to “hot money” options buying.  Generally, the smart money will purchase options to insure stable returns over a longer term.  The smart money has in-depth knowledge and data in support of their options activity. In contrast, “Hot money” acts based on speculation, seeking a large payoff.

At the moment, hot money is more cautious than smart money, and the back-test for this model supports a long position.  When the Sentiment goes below zero (and the line moves from green to red), then this model will cut all equity exposure to zero.  When the market is in the red regime below, the market has an overall negative return.

SPX Skew – the Price of Protection

In evaluating equity market risk, we also consider the cost of buying puts versus the cost of buying calls.  When puts command a larger-than-usual premium to calls, then the market will have higher volatility (in the red zone below), and this might be a signal reduce equity exposure. 

Skew suggests that investors are neither bullish nor bearish at the moment.

Gamma Band Background

Market participants are increasingly aware of how the options markets can affect the equity markets in a way that can be viewed as the “tail wagging the dog.” 

We created a Gamma Band indicator to demonstrate the effectiveness of the Gamma Neutral level in reducing equity tail risk.  In our model, we compare the daily close of the SPX to the Gamma Neutral and Lower band levels to adjust our equity exposure allocation from 0% to 100%.  

We back-tested this strategy from 2007 to the present and discovered a 74% increase in risk-adjusted returns (shown below).  The Gamma Band model is a relatively slow but reliable signal if one’s goal is to increase risk-adjusted returns.  Free samples of all of our daily reports can be downloaded from our website.
