超指数可加模型下障碍期权的定价与套期保值

Pricing and hedging barrier options in a hyper-exponential additive model

Marc Jeannin, Martijn Pistorius

摘要:

在本文中,我们发展了一个算法来计算的价格和希腊的障碍期权在一个超指数可加模型与分段常数参数。我们得到了一个明确的半解析表达式的首次通过概率。该解决方案依赖于一个随机化和显式矩阵Wiener-Hopf分解。利用这一结果,我们得到明确的表达式的拉普拉斯-傅立叶变换的价格和希腊的障碍期权。作为一个数值说明,价格和希腊的向下和在数字和向下和在看涨期权计算的一组参数,通过同时校准Stoxx 50 E看涨期权跨罢工和四个不同的期限。通过与Monte-Carlo模拟结果的比较,我们表明该方法是快速,准确,稳定。

英文摘要:

In this paper we develop an algorithm to calculate the prices and Greeks of barrier options in a hyper-exponential additive model with piecewise constant parameters. We obtain an explicit semi-analytical expression for the first-passage probability. The solution rests on a randomization and an explicit matrix Wiener-Hopf factorization. Employing this result we derive explicit expressions for the Laplace-Fourier transforms of the prices and Greeks of barrier options. As a numerical illustration, the prices and Greeks of down-and-in digital and down-and-in call options are calculated for a set of parameters obtained by a simultaneous calibration to Stoxx50E call options across strikes and four different maturities. By comparing the results with Monte-Carlo simulations, we show that the method is fast, accurate, and stable.
