Quantitative analysis (quant analysis) in finance refers to the use of mathematical models, statistical methods, and large datasets to evaluate investments, identify trading signals, manage risk, and construct portfolios — as distinct from qualitative analysis which relies on judgment, management assessment, and non-numeric factors. In equity markets, quantitative analysis includes factor-based stock screening (using metrics like P/E, ROE, momentum, and earnings growth), algorithmic trading strategy development, portfolio optimisation using mean-variance analysis, and risk modelling through Value at Risk (VaR) and Monte Carlo simulations. In India, quantitative analysis is increasingly used by institutional investors, hedge funds, and sophisticated retail traders — particularly for Nifty 50 and Bank Nifty options strategies. The growth of India's fintech ecosystem and the availability of granular financial data through platforms like BSE, NSE, and SEBI databases has made quantitative analysis more accessible to a broader range of market participants.
