Their primary goal is to use data and mathematical models to make informed decisions about trading, risk management, and investment strategies.

Key aspects of a quant's role include:

Mathematical Modeling: Quants develop mathematical models to understand and predict behaviour be it markets. These models may involve statistical analysis, calculus, and other advanced mathematical techniques.

Algorithmic Trading: Many quants are involved in designing and implementing algorithmic trading strategies. These automated systems execute trades based on predefined criteria, often leveraging high-frequency trading techniques.

Risk Management: Quants play a crucial role in assessing and managing risk. They develop models to quantify potential risks associated with financial instruments and investment portfolios.

Data Analysis: Quants work with vast amounts of financial data, employing statistical tools and programming languages to extract meaningful insights. They may use historical data to backtest and refine their models.

Programming Skills: Proficiency in programming languages like Python, R, and C++ is essential for quants. They use coding to implement models, analyze data, and build algorithmic trading systems.

Financial Markets Knowledge: Quants need a deep understanding of financial markets, instruments, and economic factors that can impact asset prices. This knowledge is crucial for developing accurate models.
