Consider the case where the option price is changing, and you want to know how this affects the underlying stock price. This is a problem of findingSfrom the Black–Scholes formula given the known parametersK,σ,T,r, andC. For example, after one month, the price of the same call option...
Discover the Black-Scholes Model, how it came to be, and its importance and uses. Know its formula and its variables and learn how to calculate it...
The Black-Scholes formulas for call option (C) and put option (P) prices are: The two formulas are very similar. There are four terms in each formula. I will again calculate them in separate cells first and then combine them in the final call and put formulas. ...
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,布莱克和斯科尔斯...
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...

we do have nice equations to describe their price under the Black-Scholes model. This is again a result of modelling the stock price under a lognormal distribution (which comes from the Brownian Motion), and therefore we can deduce a general pricing formula for European options. If you are ...
