指数Lévy模型的期权校准:置信区间和经验结果

Option calibration of exponential Lévy models: Confidence intervals and empirical results

Jakob Söhl, Mathias Trabs

摘要:

通过观察欧式看跌期权和看涨期权的价格,我们对指数Lévy模型进行了非参数校正.我们讨论了有限跳活动的Lévy模型以及自分解Lévy模型的谱估计过程的有效实现。基于有限的样本方差,置信区间构造的波动性,漂移,逐点,跳跃密度。如模拟所示,这些区间在大小和覆盖概率方面表现良好。我们比较了德国DAX指数上基于期权的有限和无限跳跃活动的程序的性能,发现这两种方法都取得了良好的校准结果。研究了当期权价格在一个交易日序列中观测时有限活动模型的稳定性。

英文摘要:

Observing prices of European put and call options, we calibrate exponential Lévy models nonparametrically. We discuss the efficient implementation of the spectral estimation procedures for Lévy models of finite jump activity as well as for self-decomposable Lévy models. Based on finite sample variances, confidence intervals are constructed for the volatility, for the drift and, pointwise, for the jump density. As demonstrated by simulations, these intervals perform well in terms of size and coverage probabilities. We compare the performance of the procedures for finite and infinite jump activity based on options on the German DAX index and find that both methods achieve good calibration results. The stability of the finite activity model is studied when the option prices are observed in a sequence of trading days.
