本文主要讲解金工金数公式里最常见的 Black-Scholes Formula 的推导方法. 在 Fischer Black 和 Myron Scholes 1973年发表的文章中, 提出了一种数学模型来描述金融衍生品价格(比如期权)的演变 (后来称为Black-Scholes Partial Differential Equation), 并给出了相应欧式看涨期权(European call option) 和看跌期权(Europe...
期权的估值 布莱克-斯科尔斯期权定价公式(Black-Scholes formula)在财经界已经被奉为圭臬。我们在编制财务报表时,需要使用它对股票卖空期权进行估值。计算的关键变量包括合约的到期日和行权价格,以及分析师的波动预期、利率变化和分红情况。 然而,如果将这个公式运用至长期的时间段,它可能会产生荒谬的结论。平心而论,布莱...
Black-Scholes Formulas是一个针对Plain Vanilla European Call and Put Options的定价方式,其中的根本假设是资产价格服从Lognormal Distribution:Ln(S(t2)S(t1))=(μ−q−σ2/2)(t2−t1)+σt2−t1Z,其中Z服从标准正态分布N(μ,σ2),这一分布的均值和标准差分别被我们称为drift和volatility,它们代表了...
These notes look at a number of ways of arriving at the Black - Scholes formula for the price of a European call option. It is assumed that the reader is familiar with the idea of an admissible self-financing portfolio, the definition of a European call option and elementary stochasti...
