What is Quantitative Trading?
Quantitative trading, or "quant trading," uses mathematical models and algorithms to make trading decisions. Unlike discretionary trading where decisions are made based on intuition and analysis, quant trading relies on data-driven rules.
The Core Idea
At its heart, a quantitative strategy answers three questions:
- When to enter? - What conditions trigger a buy?
- When to exit? - What conditions trigger a sell?
- How much? - What position size should I take?
These rules are codified into algorithms that can process vast amounts of data in milliseconds - far faster than any human could.
Why Quantitative Trading?
Advantages
| Aspect | Discretionary Trading | Quantitative Trading |
|---|---|---|
| Speed | Seconds to minutes | Milliseconds |
| Emotion | Prone to fear/greed | Rule-based, no emotion |
| Consistency | Varies day to day | Same rules every time |
| Scalability | Limited by capacity | Can manage many strategies |
| Backtesting | Difficult to verify | Rigorous historical testing |
What Quant Traders Do
- Research: Identify patterns and inefficiencies in markets
- Develop: Create mathematical models to exploit these patterns
- Backtest: Test strategies on historical data
- Deploy: Run strategies in live markets
- Monitor: Track performance and adjust as needed
Types of Quantitative Strategies
Trend Following
Profit from sustained price movements in one direction.
Signal: Buy when price > 200-day moving average
Sell when price < 200-day moving average
Mean Reversion
Profit from prices returning to their average.
Signal: Buy when price drops 2 standard deviations below mean
Sell when price rises 2 standard deviations above mean
Statistical Arbitrage
Profit from statistical relationships between securities.
Signal: When Stock A and Stock B diverge beyond threshold
Short the high one, buy the low one
Close positions when they converge
Market Making
Profit from bid-ask spread by providing liquidity.
Signal: Place both buy and sell limit orders
Profit from spread
Manage inventory risk
