商品市场局部波动率模型及其在线校正

Local Volatility Models in Commodity Markets and Online Calibration

Vinicius Albani, Uri M. Ascher, Jorge P. Zubelli

摘要:

本文利用欧式期权价格建立了一个商品期货期权定价的局部波动率模型。相应的校准问题是在一个在线框架内解决的,允许使用多个价格表面。由于观察潜在的未来价格的不确定性转化为数据位置的不确定性,我们提出了一个基于模型的调整,这样的价格,提高重建和微笑坚持。为了解决不适定性的校准问题,我们将通过一个明智的设计Tikhonov型正则化的先验信息。广泛的实证测试与市场以及合成数据被用来证明的方法和算法的有效性。

英文摘要:

We introduce a local volatility model for the valuation of options on commodity futures by using European vanilla option prices. The corresponding calibration problem is addressed within an online framework, allowing the use of multiple price surfaces. Since uncertainty in the observation of the underlying future prices translates to uncertainty in data locations, we propose a model-based adjustment of such prices that improves reconstructions and smile adherence. In order to tackle the ill-posedness of the calibration problem we incorporate a priori information through a judiciously designed Tikhonov-type regularization. Extensive empirical tests with market as well as synthetic data are used to demonstrate the effectiveness of the methodology and algorithms.
