Simple Definition

Making trading decisions from math, data, and statistics rather than gut feeling or a story about a company.

Why It Matters

Quantitative (or 'quant') trading treats markets as a data problem. Instead of asking 'do I believe in this company?', a quant asks 'what does the data say tends to happen when these measurable conditions appear?' The approach leans on statistics, probability, and testing. Algorithmic trading is usually how a quant strategy gets executed — the quant designs the rules, and an algorithm runs them.

Key Points

  • Decisions driven by data and statistics, not narrative or intuition
  • Relies heavily on testing and probability rather than single predictions
  • Often executed through algorithmic trading once the rules are set
