如何使Dupire的局部波动率与跳跃一起工作

How to make Dupire's local volatility work with jumps

Peter K. Friz, Stefan Gerhold, Marc Yor

摘要:

有几个(数学)原因为什么Dupire的公式在非扩散设置失败。然而,在实践中,期权数据的临时预处理工作得相当好。在这篇文章中,我们试图解释为什么。特别是,我们提出了一个正规化程序的选项数据,使Dupire的本地卷扩散过程重新创建正确的期权价格,即使在明显存在的跳跃。

英文摘要:

There are several (mathematical) reasons why Dupire's formula fails in the non-diffusion setting. And yet, in practice, ad-hoc preconditioning of the option data works reasonably well. In this note we attempt to explain why. In particular, we propose a regularization procedure of the option data so that Dupire's local vol diffusion process recreates the correct option prices, even in manifest presence of jumps.
