摘要
为了提高纯跳跃CGM Y模型期权定价精度,在恒生指数期权市场比较数值计算和蒙特卡罗模拟两种技术。结果显示:数值计算比模拟方法更加快捷,但不适用于虚值期权定价;传统蒙特卡罗模拟方法在虚值范围内定价较为准确,但效率低下;引入复数合流超几何函数的新模拟方法在保持精度不变的同时极大提高了计算效率,同时可避免模型参数限制、规避死循环。
In order to enhance the precision of option pricing for the pure-jump of CGMY model,two kinds of technologies are compared in the HSI option market with numerical method and Monte Carlo simulation.The conclusion shows that:(1) the numerical method is quicker than the simulation,but unsuitable for pricing out-of-the-money option;(2) the traditional Monte Carlo simulation for OTM option is more accurate,but less efficient;(3) the calculation efficiency is raised enormously after introducing complex confluence hypergeometry function and maintained precision invariable, and meanwhile the method can avoid the limitation of model parameter,and dodge the endless loop.
