Scaling Deltas in High IV

Market Measures

Options involve risk and are not suitable for all investors. Please read Characteristics and Risks of Standardized Options before deciding to invest in options.

We have lots of deltas to choose from when looking at an option chain.

We generally default to 16 deltas , but can we optimize our P/L by choosing delta based on IV Rank?

  • SPY
  • 2005 - 2017, 45 DTE
  • Compared selling:
    • 16, 20, 30 delta strangles when IVR > 50
    • 16, 20, 30 delta strangles when IVR < 50
  • Recorded P/L, win rate

We find that scaling our deltas higher when IVR is higher provides substantial increases in P/L. When IVR is low, P/L stays relatively flat across most deltas, making it not worthwhile to scale up.
