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...
Black㏒choles formulaEuropean call optionsGirsanov's theoremriskless assetrisky assetThis chapter concentrates on the classical European options, either call or put options, on stocks. These options are abundantly traded and their treatment by Black, Scholes and Merton was the stepping﹕tone of the ...
The Black-Scholes call option formula is calculated by multiplying the stock price by the cumulative standard normal probability distribution function. Thenet present value (NPV)of the strike price multiplied by the cumulative standard normal distribution is then subtracted from the resulting value of ...

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...
Find Call Option Price The Black–Scholes formula models the price of European call options [1]. For a non-dividend-paying underlying stock, the parameters of the formula are defined as: Sis the current stock price or spot price. Kis the exercise or strike price. ...
With the Black-Scholes option formula, this paper attempts to study the sensitivity of single stock' call option named Industrial and Commercial Bank of China Limited to stock price changes, time changes and the situation that both of them occur. The simulation results were achieved based SAS, ...
The Black-Scholes formula: C = S N(d1) – X e-rTN(d2) where C = price of the call option S = price of the underlying stock X = option exercise price r = risk-free interest rate T = current time until expiration N = area under the normal curve ...
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. ...
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...
