Strategy #360

Cointegration Mean Reversion

Entry Logic

  • Long Entry: The spread between two cointegrated assets widens to a statistically significant level. Buy the underperforming asset and sell the overperforming asset.
  • Short Entry: Not applicable.
  • Confirmation: The spread begins to revert to its mean.
  • Timeframe: Daily.
  • Location: Extreme deviation in the spread of a cointegrated pair.
  • Market Condition: Any.

Exit Logic

  • Profit Target: The spread returns to its mean.
  • Scaling Out: No.
  • Trailing Stop: No.
  • Signal Failure: Exit if the spread continues to widen.
  • Opposite Signal: Not applicable.
  • Time Expiration: Hold as long as the cointegration relationship holds.
  • Momentum Loss: Exit if the reversion stalls.

Stop Loss Structure

  • Hard Stop: A pre-defined maximum spread width, determined by backtesting.
  • Soft Stop: If the cointegration test (e.g., Augmented Dickey-Fuller test) fails.
  • Max Dollar Loss: Varies.
  • Max Percent Loss: 4%.
  • Structural Stop: Not applicable.

Risk Management Framework

  • Risk Per Trade: 2%.
  • Daily Limit: Not applicable.
  • Weekly Limit: 6%.
  • Max Drawdown: 20%.
  • R:R Requirement: 2:1.

Position Sizing Model

  • Sizing Approach: Based on the hedge ratio determined by the cointegration analysis.
  • Volatility Adjustment: No.
  • Conviction Sizing: No.
  • Scaling In: No.
  • Scaling Out: No.

Trade Filtering

  • Market Conditions: Requires a statistically significant cointegration relationship.
  • Setups: Based on a cointegration test.
  • Instruments: Any pair of assets that have a long-term economic relationship (e.g., different classes of oil, different government bonds).
  • Time Restrictions: None.
  • Chop/News Avoidance: Be aware of news that could break the economic link between the assets.

Context Framework

  • Trend Direction: Not applicable.
  • VWAP Relationship: Not applicable.
  • MA Relationship: Not applicable.
  • Range Location: At an extreme of the spread's range.
  • Higher TF Alignment: Not applicable.

Trade Management Rules

  • Breakeven: No.
  • Scale Out: No.
  • Add Size: No.
  • Fast vs Slow Moves: This is a very slow-moving, long-term strategy.

Time Rules

  • Optimal Window: Any.
  • Times to Avoid: None.
  • Session Notes: A sophisticated quantitative strategy.

Setup Classification

  • A+ Setup: A strong cointegration relationship with a large deviation from the mean.
  • A Setup: A moderate cointegration relationship with a moderate deviation.
  • B Setup: A weak cointegration relationship.
  • C Setup: No cointegration.

Market Selection Criteria

  • Instruments: Pairs that pass a cointegration test with a high degree of confidence.
  • Volume: High.
  • Volatility: Any.

Statistical Edge Metrics

  • Win Rate: 70-80%.
  • Avg Win: 2.5R.
  • Avg Loss: 1R.
  • Profit Factor: 3.0.
  • Expectancy: +1.25R.

Failure Conditions

  • Market Conditions: A breakdown in the fundamental economic relationship between the two assets.
  • Specific Scenarios: A technological innovation that makes one asset obsolete.

Psychological Rules

  • Discipline: Requires a deep understanding of statistics and econometrics. Must trust the model.

Advanced Components

  • Regime Detection: The cointegration test itself is a form of regime detection.
  • Filters: Only trade pairs with a stable cointegration relationship over a long period.
  • Correlation: Cointegration is a more specific and powerful concept than correlation.
  • MTF Alignment: Not applicable.

Location

  • Strongest: In markets where there are strong, stable economic links between assets.
  • Weakest: In markets where assets are driven by speculation rather than fundamentals.
