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...
It has an example of valuing a Put option using black scholes formula. Unlike valuation of a call option for Pa it is getting the PV of the estimated net cash flows after exercise of the option as the cost of the project plus the NPV. Should this not be the NPV less the cost for t...

所以对digital option定价也更简单,也就是我们上面的call option的second term: 同样的put option的价格: 例子: 5. Power Option 我们现在讲到期日T的power option,power option实际上是欧式期权中的一种,他的payoff如下 然后我们一般都是从risk-neutral valuation formula开始试图对option进行定价(numerate= B_t),...
There is no q in the formula for d1 Therefore, if dividend yield is zero, then e-qt = 1 and the models are identical. Black-Scholes Greeks Formulas Below you can find formulas for the most commonly used option Greeks. Some of the Greeks (gamma and vega) are the same for calls and...
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...
This calculator uses the Black-Scholes formula to compute the price of a put option, given the option's time to maturity and strike price, the volatility and spot price of the underlying stock, and the risk-free rate of return. The Black-Scholes option-pricing model can be used to compute...

Black-Scholes option pricing model (also called Black-Scholes-Merton Model) values a European-style call or put option based on the current price of the underlying (asset), the option’s exercise price, the underlying’s volatility, the option’s time to
