Frequently asked questions
- What is IYT gamma exposure (GEX)?
- Gamma exposure (GEX) measures how much market makers must hedge when IYT stock moves. Positive GEX means dealers are long gamma and will hedge in a stabilizing way (buy dips, sell rallies), while negative GEX means their hedging amplifies moves.
- What is IYT delta exposure (DEX)?
- Delta exposure (DEX) shows the net directional options exposure on IYT. It represents how many shares market makers need to buy or sell to stay delta-neutral. Large DEX shifts can indicate significant directional positioning.
- How do IYT Vanna and Charm affect the stock?
- Vanna measures how IYT option deltas change with implied volatility — when IV drops, positive vanna exposure forces dealers to buy shares, creating upward pressure. Charm measures delta decay over time, causing similar hedging flows as options approach expiration.
