摘要
利用分数维Ito公式和Δ-对冲技巧,导出了分数维Hull-White利率下原生资产价格服从分数跳-扩散过程的欧式期权定价模型;利用偏微分方程法,求得了该模型的解析解,且导出了上述条件下的欧式看涨期权定价公式、欧式看涨-看跌期权平价公式和欧式看跌期权的定价公式;并由此得到了具相同条件下的欧式数字看涨、看跌期权的定价公式及平价公式。
The formulas for the European pricing option under fractional Hull-White interest rate model,in which the underlying asset price obeys the fractional Brownian motion,were obtained by using the fractional Ito formula and the hedging technique.Furthermore,through the partial differential equation method,we obtained the analytical solution of the model and derived the pricing formula of European call option,European option call-put parity relationship under the conditions above mentioned and the pricing formula of European put options.By generalizing the results,the pricing formulas and parity formulas of European call and put digital options with the same conditions as the cases above mentioned were derived.
