本文先介绍了标准期权即Black-Scholes单因素期权定价模型的解析解,通过修正Black-Scholes期权定价模型的基本假设条件:在一只股票受两个有相关性的变量因素的情况下,通过引入新变量将相关性转化为独立性,采用Girsanov公式和ItO赞公式,推导了两相关因素型期权定价公式。最后通过实例分析验证了结果的有效性。 This paper first introduces the analytical solution of the standard option, Black-Scholes option pricing model. By amending the basic assumptions of the Black-Scholes option pricing model, in the case of a stock subject to two correlated variables, The new variables were introduced to transform the correlation into independence, and the formulas of two related factor-based options were derived by Girsanov’s formula and ItO’s’s formula. Finally, the validity of the result is verified through an example analysis.
