![]() Prices without needing to know the actual probability of various future stock prices. ![]() This assumption ensures that the model is consistent with risk-neutral valuation, allowing the calculation of option Growth rate of the underlying asset is equal to the risk-free rate. The term d1 in the Black-Scholes formula indeed incorporates elements such as the risk-free rate, the stock’s volatility, and the time to expiration. In the risk-neutral world (where mu = r ), N(d1) can be thought of as the factor by which the stock price (contingent on exercise) exceeds the exercise price, adjusted by the risk-neutral Where N(d1) is the cumulative distribution function of the standard normal distribution evaluated at d1. The Delta of a European call option in the Black-Scholes model can be expressed as: InĪ risk-neutral world, investors are indifferent to risk. Under this assumption, we eliminate the risk premium associated with any asset. In risk-neutral valuation, all assets are assumed to grow at the risk-free rate (r), which means mu = r. The connection between the Delta of an option and the probability of that option expiring in-the-money under the assumption mu = r is rooted in the Black-Scholes option pricing model and ![]() Why delta is not the probability of an option expiring in the money in layman’s terms… ![]()
