“…A straightforward extension is to explore how well the hedging strategies work for other stochastic volatility processes for the underlying asset and for processes where there are jumps in the price of the underlying asset. Alternatively, a joint process for the asset price and volatility surface, such as that proposed by Francois et al (2023), can be investigated. The analysis should incorporate the way delta, gamma, and vega are normally calculated by practitioners (i.e., by substituting the implied volatility into the Black-Scholes-Merton formulas).…”

“…They also propose a second approach based on FPCA of the changes of the log IV surfaces and model the coefficients by Ornstein-Uhlenbeck processes, identical to what was done in , but now including a down-sampling method for reducing static arbitrage. Francois et al (2023) model the joint dynamics of the IV surfaces and its underlying using a five-factor parametric representation of the IV surfaces. The underlying returns and the factor coefficients are modeled using GARCH-type models, with a Gaussian copula capturing the dependence structure.…”
