分数次Black-Scholes模型下美式期权定价的一种二次近似方法

A Quadratic Approximation Method for American Option Pricing under the Fractional Black-Scholes Model

在分数次Black-Scholes模型下,用二次近似定价法推导出支付红利的美式看跌期权价格的近似解析式,然后进行数值计算,并与用显式差分法计算的结果作对比.二次近似定价法可行,但是还有待改进.

With the fractional Black-Scholes model,the approximated price formula for an American put option are derived by the quadratic approximation,and then their numerical solutions compared with that of the finite difference method.The results show that the quadratic approximation is feasible but needed to be improved.
