Understanding Expected Move

What is the Expected Move?

The expected move is the price range that options traders believe an asset will stay within by a specific expiration date. It is calculated using the prices of at-the-money options (straddles) and represents a one-standard-deviation (±1σ) probability, which is approximately 68%.

How to interpret the outputs

The chart visualizes the potential price range (the “cone”) for the asset over time, with both one-standard-deviation (±1σ) and two-standard-deviation (±2σ, ~95% probability) boundaries. The table below quantifies this, showing the expected move in both points and as a percentage for each upcoming expiration. This lets you see exactly how much volatility the market is pricing in for different time horizons.

Practical applications

  • Set realistic price targets for trades based on market-implied probabilities.
  • Determine optimal strike prices for spreads, condors, or straddles.
  • Compare your thesis with the market’s implied consensus to judge risk/reward.
  • Spot when expectations for volatility are unusually high or low versus history.
