Quantitative finance is the application of advanced mathematics, statistics, and computational techniques to model, price, and manage financial instruments. This overview covers core topics from stochastic processes and derivative pricing to portfolio optimization, interest rate modeling, and modern machine learning applications in trading and risk. It reflects the rigor of a PhD-level treatment, blending theory with implementation, and is designed for those seeking a deep understanding of how quantitative methods drive decision-making in today’s capital markets.
Quantitative finance is applied across virtually every function of modern capital markets. From trading desks and risk teams to asset managers and fintech platforms, these models drive pricing, hedging, optimization, and forecasting in highly dynamic environments. The examples below reflect the field’s breadth, showing how quantitative tools solve real-world problems across derivatives, credit, market structure, and emerging technologies.
The Greeks are fundamental sensitivity measures that quantify how the value of a derivative changes in response to underlying risk factors. They form the backbone of risk management in options portfolios, guiding hedging strategies, capital allocation, and exposure monitoring. Traders and quants rely on Greeks—such as delta, gamma, vega, theta, and rho—to understand directional risk, convexity, volatility exposure, time decay, and interest rate sensitivity across complex financial instruments.
