SPX Greek Hedging

Greek Hedging (SPX) estimates the day’s dealer rebalancing flows implied by the current options book  essentially how much trading may be required for dealers to remain hedged as prices and volatility move.

Here the dominant signal is Delta hedging ($109.6B), pointing to extremely large price-linked hedging activity that may require dealers to buy underlying exposure as prices move, reinforcing directional momentum. Vega hedging ($5.46B) shows strong sensitivity to changes in implied volatility, indicating that volatility shifts could also drive meaningful hedging flows. Theta (-$25.1M) reflects a small negative impact from time decay, suggesting a slight drag as options positioning evolves over time.
