摘要
应用风险中性定价原理,研究标的股价服从分数跳扩散过程的幂期权的定价问题,并得出该情况下欧式看涨幂期权、看跌幂期权的定价公式及平价公式,并与股价服从跳扩散过程的标准欧式期权定价模型进行比较分析,并验证了布朗运动只是分数布朗运动的一种特例,可基于分数布朗运动对原有的期权定价模型进行推广.
The pricing of power option when the underlying assets following fractional jump diffusion process is mainly studied.By using the risk neutral valuation principle,the pricing formulae of power call option,put option and parity are obtained when the underlying stock price is depicted by jumping diffusion process.Then comparative analysis is made with standard European option pricing model when the underlying assets following jump diffusion process,and further Brownian motion is verified to be a special case of the fractional Brownian motion.So the original pricing of option model can be promoted based on the fractional Brownian motion.
