TQS / Fields

Where quantitative skills are used

“Quant” is not one industry. The same tools—mathematics, statistics, programming, and modeling—help people make very different decisions.

Eight fields, many questions

  • Trading and market making

    Firms continuously quote buy and sell prices and trade across many markets.

    Problems
    Order books, pricing, execution, inventory, and risk management
    Methods
    Probability, statistics, optimization, and low-latency systems
  • Systematic funds

    Models help assess patterns in data and manage portfolios systematically.

    Problems
    Signal research, portfolios, transaction costs, and risk models
    Methods
    Time series, statistics, machine learning, portfolio optimization
  • Banks and financial infrastructure

    Quantitative teams build models and systems for prices, risk, and markets.

    Problems
    Derivatives, market and credit risk, model validation, fraud detection, exchange technology
    Methods
    Stochastic modeling, numerical methods, statistics, data engineering
  • Energy and commodities

    Power, gas, and renewable generation must be scheduled despite weather and changing demand.

    Problems
    Generation forecasts, storage, dispatch, power trading, and grid balancing
    Methods
    Probabilistic forecasting, optimization, time series, weather data
  • Insurance and reinsurance

    Insurers quantify rare losses, long-term liabilities, and uncertainty.

    Problems
    Pricing, reserving, catastrophe risk, fraud, and solvency
    Methods
    Actuarial mathematics, statistics, extreme-value theory, machine learning
  • Climate, weather, and catastrophe risk

    Models estimate extreme events and their effects on infrastructure, businesses, and insurers.

    Problems
    Weather forecasts, climate risk, exposure models, and adaptation planning
    Methods
    Simulation, geospatial data, probabilistic modeling, causal inference
  • Logistics and digital marketplaces

    Platforms coordinate supply and demand and decide what goes where and when.

    Problems
    Routing, matching, dynamic pricing, inventory, and demand forecasting
    Methods
    Operations research, optimization, auctions, causal experiments
  • Sports and health

    Data informs decisions about strategy, treatment, and scarce resources.

    Problems
    Player valuation, sensor data, clinical trials, and resource planning
    Methods
    Statistics, time series, experimental design, image and sensor analysis

Tools that travel

Many of these paths start with the same foundations. Domain knowledge is added depending on the role.

  • Probability & statistics
  • Programming & data
  • Optimization
  • Quantifying uncertainty
  • Testing models critically
