Abstract :

Volatility surfaces are key to understand and characterize how the implied volatility varies, relatively strictly given a single maturity date (hence giving birth to different strips), across strike prices. If you want to be serious about option pricing, hedging, risk management volatility trading and PF construction they must estimate them correctly. On the other hand, derivative markets generates sparse, noisy non-linear and dynamically varying observations making standard parametric or interpolation based approaches ineffective. In this paper, we explore the application of volatility surface learning as a data-driven framework to extract stable and economically interpretable (volatility) structures from heterogeneous observations in financial markets. Our approach marries implied-volatility observations together with pattern recognition in the form of machine learning models being able to capture nonlinear interactions across strikes, maturities, market regimes and underlying-asset characteristics. In more general terms, the framework focuses on preprocessing of data, ensuring arbitrage-aware representation and dimensionality reduction processes throughout the modelling path while implementing supervised learning for temporal modeling and uncertainty estimation. The approach also well takes into account the need for maintaining financial stability between smoothness and no-arbitrage constraints while being responsive to volatile dynamics. The paper enumerates the techniques of using neural networks, ensemble methods, kernel-based models and hybrid approaches for improving surface reconstruction and forecasting. It highlights extrapolation, sparse market scenarios and shifts in regime as well as the interpretability of our models. Such a framework lays the groundwork for adaptive estimation of volatility surfaces to achieve greater uniformity in pricing, hedging and risk assessment throughout rapidly growing classes of derivative markets.
