3/2模型的显式解模拟方法

Explicit solution simulation method for the 3/2 model

Iro René Kouarfate, Michael A. Kouritzin, Anne MacKay

摘要:

得到了3/2随机波动率模型的显式弱解,并利用它发展了一个期权定价的模拟算法。3/2模型是一个非仿射随机波动率模型,其方差过程是CIR过程的逆过程。这里利用这个性质来获得显式弱解,类似于Kouritzin(2018)。提出了一种基于该解的仿真算法,并通过数值算例进行了验证.所得定价算法的性能与其他流行的模拟算法相当。

英文摘要:

An explicit weak solution for the 3/2 stochastic volatility model is obtained and used to develop a simulation algorithm for option pricing purposes. The 3/2 model is a non-affine stochastic volatility model whose variance process is the inverse of a CIR process. This property is exploited here to obtain an explicit weak solution, similarly to Kouritzin (2018). A simulation algorithm based on this solution is proposed and tested via numerical examples. The performance of the resulting pricing algorithm is comparable to that of other popular simulation algorithms.
