基于贝叶斯统计方法的量子期权定价的数值模拟

The Numerical Simulation of Quanto Option Prices Using Bayesian Statistical Methods

Lisha Lin, Yaqiong Li, Rui Gao, Jianhong Wu

摘要:

研究了标的资产与汇率相关的Quanto期权的定价问题。首先,我们采用贝叶斯方法估计了Quanto期权定价公式中的未知参数,包括股票的波动率、汇率的波动率和相关性。其次,我们基于贝叶斯后验预测技术和蒙特卡罗方法计算和预测了四种不同类型的Quanto期权的价格。最后,我们通过数值模拟来证明本文所采用的贝叶斯方法与其他一些现有方法相比的优势。本文是贝叶斯方法在多资产期权定价中的一个新应用。

英文摘要:

In the paper, the pricing of Quanto options is studied, where the underlying foreign asset and the exchange rate are correlated with each other. Firstly, we adopt Bayesian methods to estimate unknown parameters entering the pricing formula of Quanto options, including the volatility of stock, the volatility of exchange rate and the correlation. Secondly, we compute and predict prices of different four types of Quanto options based on Bayesian posterior prediction techniques and Monte Carlo methods. Finally, we provide numerical simulations to demonstrate the advantage of Bayesian method used in this paper comparing with some other existing methods. This paper is a new application of the Bayesian methods in the pricing of multi-asset options.
