Implied Volatility (IV)

Implied Volatility (IV) represents the market's forecast of how much a stock's price is likely to move. It's derived from current options prices — when traders are willing to pay more for options, IV rises, indicating greater expected movement.

  • Higher IV = More expensive options (and bigger expected move)
  • Lower IV = Cheaper options (market expects calm)
  • IV Crush — Rapid IV decline after a known event (like earnings). Options lose value even if stock moves.
  • IV Rank — Current IV relative to its range over the past year (0-100)
  • IV Percentile — What percent of days in the past year had lower IV than today
