As the price of the underlying asset fluctuates, the delta also changes, requiring frequent rebalancing of the hedge. For dynamic trading in the underlying asset and this vanilla option, delta-vega hedging is asymptotically optimal in the limit for small uncertainty First steps in building the intuition for an Excel based optimization model for hedging higher order Greeks.

After earnings, Delta neutral structures are used for negative Vega exposure (to profit from the IV crush) and high positive Theta, focusing on capitalizing on range-bound movement. Before earnings, Delta neutral structures (like a simple straddle) are used to gain maximum positive Vega exposure, betting on the IV rise, though Gamma risk is high. This thesis shows that the delta-hedging performance of the Black & Scholes model can significantly be improved by taking the skew-adjusted term into account.

The key measure of risk they consider is the delta of the option When barrier options are considered we find that the local delta outperforms the implied delta but there is a need to resort to more elaborate multi-instrument hedging schemes in multi-factor models in order to obtain acceptable absolute hedging performances. delta_gamma_hedge_simulation() compares delta-only vs delta-gamma hedging by adding a second option to neutralize gamma. every day) and that the agent can take a position in an at-the-money European option to manage gamma and vega.
