This paper explores effective hedging strategies through the Black-Scholes model and Monte Carlo simulations. We introduce the fundamental principles of Geometric Brownian Motion (GBM) and demonstrate how it is applied to estimate option prices and manage risk. With a detailed methodology, we generate random trials to analyze stock prices, call prices, and portfolio values. Our findings highlight the dynamics of option pricing in relation to underlying stock prices and emphasize the importance of delta hedging in reducing financial risk.

Introduction • Our assignment • Tools used to solve the problem • Monta Carlo simulation • Geometric Brownian motion (GBM) • Black-Scholes model • Delta hedge
Monte Carlo simulation • Model that gives you possible result using random variables • Calculating probabilty of random outcomes
Black and Scholes • Calculates the option price
Geometric Brownian Motion • Calculates the stock price
Delta Hedge • Changes in option price with respect to underlying stock price • Reduces risk
