Frequently asked questions

What is SPHY gamma exposure (GEX)?
Gamma exposure (GEX) measures how much market makers must hedge when SPHY 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 SPHY delta exposure (DEX)?
Delta exposure (DEX) shows the net directional options exposure on SPHY. 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 SPHY Vanna and Charm affect the stock?
Vanna measures how SPHY 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.
