We show how to implement both discrete (binomial) models and continuous (Black-Scholes) models, discuss similarities and differences in the required computational methods, and investigate issues of a practical nature, such as parameter estimation/uncertainty and effects Exam 3F/MFE covers Black-Scholes. VBA Implementation: Advanced users may choose to implement the Black-Scholes formula using Visual Basic for Applications (VBA) to create a more dynamic and customizable solution. Here, we have three “Greeks” that represent the option’s sensitivity to parameters: Delta: Measures the option price change concerning asset price, i. ) q = continuously compounded The Black-Scholes formulas for call option (C) and put option (P) prices are: The two formulas are very similar. 62 Put Option Price (P) ≈ $4. However, as the derivation of the model, which requires advanced mathematical tools, is well beyond the scope of standard finance textbooks, the model has remained a great, but mysterious, recipe for many Quasi-Random Monte Carlo Simulation of Black-Scholes for 1,000,000 (1 million) simulations .
