最近在金融建模中出现了一种新的范式:粗糙(随机)波动率。首先由Gatheral等人观察到。在高频数据中,随后在市场微观结构模型中得到,粗略波动率捕获了整个隐含波动率表面的简约关键程式化事实,包括极端偏斜(如Alfreders等人先前观察到的)。被认为超出了随机波动率模型的范围。在数学方面,马尔可夫性和部分半鞅性都丢失了。在本文中,我们表明,Hairer的正则性结构,粗糙路径理论的一个主要扩展,这引起了随机偏微分方程领域的革命,也提供了一个新的和强大的工具来分析粗糙波动率模型。
A new paradigm has emerged recently in financial modeling: rough (stochastic) volatility. First observed by Gatheral et al. in high‐frequency data, subsequently derived within market microstructure models, rough volatility captures parsimoniously key‐stylized facts of the entire implied volatility surface, including extreme skews (as observed earlier by Alòs et al.) that were thought to be outside the scope of stochastic volatility models. On the mathematical side, Markovianity and, partially, semimartingality are lost. In this paper, we show that Hairer's regularity structures, a major extension of rough path theory, which caused a revolution in the field of stochastic partial differential equations, also provide a new and powerful tool to analyze rough volatility models.
