1.4 THE BLACK-SCHOLE MODEL
The Black-Scholes model is a cornerstone of modern financial theory, providing a mathematical framework for pricing European-style options. Developed by Fischer Black, Myron Scholes, and Robert Merton in the early 1970s, the model revolutionized the field of quantitative finance.
Mathematically, the Black-Scholes model calculates the price of a European call option, which gives the holder the right to buy an underlying asset at a specified price (the strike price) on or before a specified date (the expiration date). The model assumes that the price of the underlying asset follows geometric Brownian motion, characterized by a constant volatility.
The Black-Scholes formula for the price of a European call option is given by:
where
πΆ = πΆπππ πππ‘πππ πππππ
π = πΆπ’πππππ‘ πππππ ππ π‘βπ π’ππππππ¦πππ ππ π ππ‘
πΎ = ππ‘ππππ πππππ
π = π ππ π ππππ πππ‘ππππ π‘ πππ‘π
π‘ = ππππ ππ ππ₯πππππ‘πππ
π = πΆπ’ππ’πππ‘ππ£π πππ π‘ππππ’π‘πππ ππ’πππ‘πππ ππ π‘βπ π π‘ππππππ ππππππ πππ π‘ππππ’π‘πππ
The formula derived from the Black-Scholes model computes the theoretical price of a call or put option based on the aforementioned factors. It considers the probability distribution of potential future asset prices and discounts expected payoffs back to the present value using the risk-free interest rate [5].
