Viking Analytics: Weekly Gamma Band Update 9/8/2020

Viking Analytics: Weekly Gamma Band Update 9/8/2020

We are thrilled to announce that Viking Analytics will be providing RIA Pro subscribers their Weekly Gamma Bands update. The report uses options gamma to help you better manage risk and your equity allocations. In the future, we will release this report each Monday.

9/8/2020 Gamma Band Update

  • The S&P 500 (SPX) traded towards the upper band and sold off to end the week just above the Gamma Neutral level.
  • Accordingly, if the SPX closes below the Gamma Neutral level (3397.15), our Gamma Band model will begin to reduce allocation to equities.

Background

Market participants are increasingly aware of how the options markets can affect the equity markets. In this case, it can be viewed as the “tail wagging the dog.”

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

Furthermore, we back-tested this strategy from 2007 to present. The model realized an 80% increase in risk-adjusted returns (measured by the Sharpe ratio).  Accordingly, the annual volatility of this approach, versus a long-only position, falls from 21% to 10%.
