双曲局部波动率模型的拟蒙特卡罗定价与风险分析

Pricing and Risk Analysis in Hyperbolic Local Volatility Model with Quasi Monte Carlo

Julien Hok, Sergei Kucherenko

摘要:

局部波动率模型通常比其他方法(如随机波动率模型)更准确地捕捉隐含波动率的表面。本文给出了基于双曲局部波动率模型的蒙特卡罗(MC)和拟蒙特卡罗(QMC)方法在衍生品定价和风险分析中的应用结果。在高维积分中,当被积函数的有效维数不太大时,QMC的性能优于MC。在衍生品定价和计算希腊有效的维度依赖于路径离散算法的应用。对亚式期权的计算结果表明了拟蒙特卡罗方法的优越性能,特别是对布朗桥离散方案。

英文摘要:

Local volatility models usually capture the surface of implied volatilities more accurately than other approaches, such as stochastic volatility models. We present the results of application of Monte Carlo (MC) and Quasi Monte Carlo (QMC) methods for derivative pricing and risk analysis based on Hyperbolic Local Volatility Model. In high-dimensional integration QMC shows a superior performance over MC if the effective dimension of an integrand is not too large. In application to derivative pricing and computation of Greeks effective dimensions depend on path discretization algorithms. The results presented for the Asian option show the superior performance of the Quasi Monte Carlo methods especially for the Brownian Bridge discretization scheme.
