A theoretical analysis of Guyon's toy volatility model

Pricing of Securities 2022-11-10 v2

Abstract

We provide a thorough analysis of the path-dependent volatility model introduced by Guyon \cite{G17}, proving existence and uniqueness of a strong solution, characterising its behaviour at boundary points, providing asymptotic closed-form option prices as well as deriving small-time behaviour estimates.
