Volatility is (mostly) path-dependent

J Guyon, J Lekeufack - Quantitative Finance, 2023 - Taylor & Francis
We learn from data that volatility is mostly path-dependent: up to 90% of the variance of the
implied volatility of equity indexes is explained endogenously by past index returns, and up …

Joint SPX-VIX calibration with Gaussian polynomial volatility models: deep pricing with quantization hints

EA Jaber, C Illand - arXiv preprint arXiv:2212.08297, 2022 - arxiv.org
We consider the joint SPX-VIX calibration within a general class of Gaussian polynomial
volatility models in which the volatility of the SPX is assumed to be a polynomial function of a …

Empirical analysis of rough and classical stochastic volatility models to the SPX and VIX markets

SE Rømer - Quantitative Finance, 2022 - Taylor & Francis
We conduct an empirical analysis of rough and classical stochastic volatility models to the
SPX and VIX options markets. Our analysis focusses primarily on calibration quality and is …

Joint calibration to SPX and VIX options with signature-based models

C Cuchiero, G Gazzani, J Möller… - arXiv preprint arXiv …, 2023 - arxiv.org
We consider a stochastic volatility model where the dynamics of the volatility are described
by linear functions of the (time extended) signature of a primary underlying process, which is …

EA Jaber, C Illand - arXiv preprint arXiv:2212.10917, 2022 - arxiv.org
The quintic Ornstein-Uhlenbeck volatility model is a stochastic volatility model where the
volatility process is a polynomial function of degree five of a single Ornstein-Uhlenbeck …

Deep calibration of the quadratic rough Heston model

M Rosenbaum, J Zhang - arXiv preprint arXiv:2107.01611, 2021 - arxiv.org
The quadratic rough Heston model provides a natural way to encode Zumbach effect in the
rough volatility paradigm. We apply multi-factor approximation and use deep learning …
