Implied volatility is an estimate of the future variability for the asset Because the standard normal distribution is symmetric and centered at zero, the standard normal cumulative distribution function has a very useful property: N (-x) = 1 - N (x) - N (-x) = N (x) - 1. - N (-d1) = N (d1) - 1. Relationship between Call and Put Delta. It is often said that (the absolute values of) call delta and put And we have thus verified the well known property of Black-Scholes; namely that ∆ = ∂C ∂S = Φ(d 1). This in turn yields a nice interpretation of the first term in the Black-Scholes formula in equation (1). That is S · Φ(d 1) is the value of the long position in the stock required to replicate the European call option. Note that ∆ is ブラック-ショールズ方程式（ブラック-ショールズほうていしき、英: Black-Scholes equation ）とは、デリバティブの価格づけに現れる偏微分方程式（およびその境界値問題）のことである。. 様々なデリバティブに応用できるが、特にオプションに対しての適用が著名である。 The Black-Scholes Model, or Black-Scholes-Merton (BSM) Model is used for pricing put or call options, focusing on mitigating volatility risk.
