摘要
建立了标的资产具有连续分红和交易成本的美式看跌期权的定价模型,通过无套利定价原理把该定价模型转化为带边界的变系数偏随机微分方程;采用加权有限差分法求解该变系数偏随机微分方程,计算结果与显式差分法、隐式差分法、Crank-Nicolson差分法等计算结果进行比较,其计算结果比这3种差分法更精确.
The paper aims to propose an American option pricing model for the underlying asset that has continuous divided and transaction costs.The model gives a stochastic differential equation with the variable coefficient and free boundary.The weighting different approximation method is used to solve the stochastic differential equation and the results are compared with the results of the forward different approximation method,the backward different approximation method and Crank-Nicolson different approximation method.
