Through this project, you should now have a deeper understanding of how concepts from physics, particularly stochastic pro
cesses and mathematical modelling, are applied in finance. Specifically, you should have learned:
- The Role of Stochastic Processes in Financial Models
- How random processes like Brownian motion form the foundation of financial modelling.
- The significance of geometric Brownian motion in describing asset prices.
- The Black-Scholes Model and Its Assumptions
- The mathematical basis of the Black-Scholes model and its use in pricing options.
- The key assumptions behind the model, including constant volatility and risk-free interest rates.
- Limitations and Real-World Challenges
- Why financial markets do not always behave as expected due to external shocks, human behaviour, and liquidity constraints.
- The impact of extreme events such as market crashes, which challenge the assumptions of smooth price changes.
- Adapting Physics-Based Models for Finance
- While physics provides a strong foundation for financial models, direct application often requires modifications to account for economic and behavioural factors.
- How models like jump-diffusion and stochastic volatility frameworks adjust traditional physics-based assumptions to better match real-world financial data.
- Lessons from LTCM: The Risks of Over-Reliance on Models
- How the collapse of Long-Term Capital Management (LTCM) demonstrated the dangers of assuming financial markets follow predictable, physics-inspired equations.
- The importance of balancing quantitative models with risk management and real-world awareness.
By now, you should appreciate both the power and the limitations of applying physics-based models to finance. While these models provide useful tools for understanding market behaviour, they must be adapted and applied with caution, recognizing the unpredictable and human-driven nature of financial systems.
