Machine Learning for Trillion Dollar Equation

Abstract

The Black-Scholes equation popularly known as Trillion Dollar Equation is a fundamental model in financial mathematics for option pricing, has been a cornerstone of quantitative finance since its inception. Traditional numerical methods for solving the Black-Scholes Partial Differential Equation (PDE) can be computationally intensive and may struggle with complex market conditions. This paper investigates the application of machine learning (ML) techniques to enhance the efficiency and accuracy of solving the Black-Scholes equation. We present a comprehensive analysis of various ML models, including deep learning architectures, reinforcement learning, and advanced regression techniques, to approximate solutions to the Black-Scholes PDE. The study evaluates the performance of these models in terms of computational speed, accuracy, and robustness compared to conventional numerical methods such as finite difference and Monte Carlo simulations. Through extensive simulations and empirical testing, we demonstrate that ML approaches, particularly neural networks, can significantly reduce computation time while maintaining high accuracy in option pricing. Additionally, we explore the adaptability of ML models to various market scenarios, including those with high volatility and discontinuities, where traditional methods often fail. Our results indicate that integrating ML with the Black-Scholes framework not only improves computational efficiency but also provides greater flexibility in handling real-world financial data complexities. We also discuss the potential implications of these advancements for risk management and financial decision-making.
