FCX vanna exposure, last 60 sessions

Jul 28Oct 20

Vanna is how dealers' delta changes when implied volatility moves; with positive vanna, a fall in IV pushes their hedges toward buying the underlying.

Charm is how delta drifts as time passes; it matters most into the close and into expiration, when negative charm means hedging flows lean toward selling.
