A Scientific Computing Analysis of Financial Black-Scholes and Monte Carlo Differential Equation: An American Option

Abstract

This study presents a systematic computing analysis of financial models, precisely focusing on the Black-Scholes and Monte Carlo derivative equations, to evaluate American options. American selections are exercised at any time before expiration, posing unique challenges in financial modelling due to their complex early exercise features. The Black-Scholes formulation gives a foundational framework for choice pricing, utilizing partial derivative formulations to estimate the fair value of options under definite assumptions. Nevertheless, because of its restriction, Monte Carlo computations are taken to give a better simulation scheme to overcome the posed challenges by computing wider likely underlying price path assets. This study implements a computationa approach to compare the efficacy of the Black-Scholes formulation and Monte Carlo methods in selected American pricing. A numerical scheme for solving the Black-Scholes derivative systems and a variance reduction technique for enhancing the effectiveness of Monte Carlo simulations are adopted. Our analysisl reveals that while the Black-Scholes model provides a useful approximation, Monte Carlo simulations deliver more accurate and flexible results for American options, especially in scenarios with substantial volatility and early exercise potential. The outcomes underscore the importance of sophisticated numerical methods in financial engineering and highlight the trade-offs between analytical tractability and numerical precision.
