均值回归跳跃扩散下的快速能源衍生品定价

文章 arXiv papers · 作者: Nicola Cufaro Petroni et al.

总结

本文介绍能源现货价格的模拟方法,将价格建模为两个独立过程之和的指数:均值回归的奥恩斯坦–乌伦贝克过程和纯跳跃过程。跳跃部分遵循复合泊松过程,跳跃幅度服从正负双向指数分布,使模型既能表示常规均值回归,也能表示偶发的价格尖峰。

据称,所提出的方法精确且计算速度快,并被用于在不同跳跃扩散设定下为亚洲期权、天然气储存合约和摆动期权定价。本文强调计算优势,但所提供文本未给出数值基准、校准细节或定价比较。因此,该模型的实用性取决于其假设与相关能源市场的匹配程度,以及摘要以外的证据。

核心观点

  • 现货价格被建模为均值回归过程与跳跃过程之和的指数。
  • 跳跃过程为复合泊松过程,跳跃幅度服从正负双向指数分布。
  • 这些方法应用于亚洲期权、天然气储存和摆动合约。
  • 本文称模拟精确且快速,但未提供基准测试结果或校准细节。

# Fast Pricing of Energy Derivatives with Mean-reverting Jump-diffusion Processes









Most energy and commodity markets exhibit mean-reversion and occasional distinctive price spikes, which results in demand for derivative products which protect the holder against high prices. To this end, in this paper we present exact and fast methodologies for the simulation of the spot price dynamics modeled as the exponential of the sum of an Ornstein-Uhlenbeck and an independent pure jump process, where the latter one is driven by a compound Poisson process with (bilateral) exponentially distributed jumps. These methodologies are finally applied to the pricing of Asian options, gas storages and swings under different combinations of jump-diffusion market models, and the apparent computational advantages of the proposed procedures are emphasized.
