Cointegration Analysis
Cointegration testing identifies pairs of assets that share a long-run equilibrium relationship, enabling statistical arbitrage and pairs trading strategies.
What Is Cointegration?
Two price series are cointegrated when they are individually non-stationary (random walks) but a linear combination of them is stationary (mean-reverting). Intuitively, the prices may wander apart temporarily but are pulled back to an equilibrium spread over time.
Cointegration vs Correlation
| Property | Correlation | Cointegration |
|---|---|---|
| Measures | Short-term co-movement | Long-run equilibrium |
| Stationarity | Requires stationary returns | Works with non-stationary prices |
| Time horizon | Can change rapidly | Stable over months/years |
| Trading use | Momentum/trend signals | Mean-reversion pairs trades |
| Failure mode | Breaks in regime changes | Breaks on structural shifts |
Two assets can be highly correlated but not cointegrated (e.g., two unrelated uptrends). Conversely, cointegrated assets may have low short-term correlation during temporary divergences — which is exactly when pairs trades are entered.
Why It Matters
- Pairs trading: Long the underperformer, short the outperformer, profit on convergence
- Statistical arbitrage: Systematic mean-reversion on spread z-scores
- Spread trading: Trade the spread directly as a synthetic instrument
- Risk hedging: Cointegrated hedge ratios minimize tracking error over time
Methods
1. Engle-Granger Two-Step
The most common approach for two series.
Step 1 — Regress Y on X using OLS:
Y_t = α + β * X_t + ε_t
Step 2 — Test the residuals ε_t for stationarity using the ADF test.
- If residuals are stationary (p < 0.05) → Y and X are cointegrated
- β is the hedge ratio for the pairs trade
- α is the long-run mean of the spread
Important: Engle-Granger critical values differ from standard ADF critical values. For n=2 series: 1% = -3.90, 5% = -3.34, 10% = -3.04.
Asymmetry warning: Testing YX can give a different result than XY. Always
test both directions and use the stronger result.
from scipy import stats
import numpy as np
from statsmodels.tsa.stattools import adfuller
# Step 1: OLS regression
slope, intercept, _, _, _ = stats.linregress(x_prices, y_prices)
hedge_ratio = slope
# Step 2: Test residuals
residuals = y_prices - hedge_ratio * x_prices - intercept
adf_stat, p_value, _, _, crit_values, _ = adfuller(residuals, maxlag=None, autolag="AIC")
cointegrated = p_value < 0.05
2. Johansen Test
Tests multiple series simultaneously and returns the number of cointegrating relationships. More powerful than Engle-Granger for >2 series.
- Based on a VAR model: ΔY_t = Π·Y_{t-1} + Σ Γ_i·ΔY_{t-i} + ε_t
- Tests the rank of the Π matrix
- Uses trace test and maximum eigenvalue test
- Returns: number of cointegrating vectors and the vectors themselves
from statsmodels.tsa.vector_ar.vecm import coint_johansen
# data: T×N array of price series
result = coint_johansen(data, det_order=0, k_ar_diff=1)
# Trace statistic vs critical values (90%, 95%, 99%)
trace_stats = result.lr1 # Trace statistics
trace_crit = result.cvt # Critical values
max_eigen_stats = result.lr2 # Max eigenvalue statistics
max_eigen_crit = result.cvm # Critical values
# Cointegrating vectors
coint_vectors = result.evec
3. Phillips-Ouliaris
Similar to Engle-Granger but uses Phillips-Perron style test statistics
instead of ADF. More robust to heteroskedasticity and serial correlation in
the residuals. Available via statsmodels.tsa.stattools.coint.
from statsmodels.tsa.stattools import coint
# Returns: test statistic, p-value, critical values
t_stat, p_value, crit_values = coint(y_prices, x_prices)
cointegrated = p_value < 0.05
Practical Workflow
Step 1: Screen Pairs by Correlation
Pre-filter using Pearson correlation > 0.7 to reduce the number of cointegration tests (which are more expensive).
Step 2: Test Cointegration
Run Engle-Granger in both directions. Use p < 0.05 threshold.
Step 3: Estimate Hedge Ratio
Use OLS for simplicity. For production, consider Total Least Squares or
Dynamic OLS (see references/methodology.md).
Step 4: Compute Spread
spread = y_prices - hedge_ratio * x_prices - intercept
z_score = (spread - spread.mean()) / spread.std()
Step 5: Test Spread for Mean Reversion
- ADF test: p < 0.05 confirms stationarity
- Hurst exponent: H < 0.5 indicates mean reversion (H ≈ 0.5 = random walk)
- Half-life: λ from AR(1) on spread; half-life = -ln(2)/ln(λ)
- Viable pairs: half-life between 5 and 60 days
Step 6: Trade the Spread
If the spread is mean-reverting, it is a viable pairs trade candidate.
See references/pairs_trading.md for entry/exit rules and risk management.
Rolling Cointegration
Cointegration relationships can break down over time due to structural changes, regime shifts, or evolving market dynamics.
Rolling Window Approach
Test cointegration on rolling 60–90 day windows:
window = 60
rolling_pvalues = []
rolling_hedges = []
for i in range(window, len(prices)):
y_win = y_prices[i - window:i]
x_win = x_prices[i - window:i]
_, p_val, _ = coint(y_win, x_win)
slope, intercept, _, _, _ = stats.linregress(x_win, y_win)
rolling_pvalues.append(p_val)
rolling_hedges.append(slope)
Monitoring Signals
| Signal | Healthy | Warning | Stop Trading |
|---|---|---|---|
| Rolling p-value | < 0.05 | 0.05–0.10 | > 0.10 |
| Hedge ratio drift | < 10% change | 10–25% change | > 25% change |
| Spread half-life | 5–60 days | 60–120 days | > 120 days or < 5 |
Crypto Pairs Candidates
Layer-1 Correlation
- SOL vs ETH — L1 sector beta, often cointegrated during trending markets
- SOL vs AVAX — alternative L1 correlation
Stablecoins
- USDC vs USDT — should be perfectly cointegrated (peg arbitrage)
- Useful as a sanity check for your cointegration pipeline
Liquid Staking Derivatives
- mSOL vs jitoSOL — both track SOL staking yield
- stSOL vs mSOL — Lido vs Marinade staking
Same-Sector Tokens
- DEX tokens: RAY vs ORCA
- Lending tokens: cross-protocol comparison
- Meme tokens: rarely cointegrated, high risk
Common Pitfalls
-
Spurious cointegration — Two trending series (both up in a bull market) may appear cointegrated. Always test on sufficient data (>200 observations) and check out-of-sample stability.
-
Structural breaks — A fundamental change (protocol upgrade, tokenomics change) can permanently break cointegration. Monitor rolling p-values.
-
Look-ahead bias — Estimating the hedge ratio on the full sample and then backtesting on the same sample inflates results. Always use walk-forward estimation.
-
Too-short sample — Cointegration tests need >100 observations minimum, ideally >200, to have reasonable power.
-
Ignoring transaction costs — Pairs trades involve 4 transactions per round trip. At 0.3% per leg, that is 1.2% in costs that the spread must overcome.
-
Asymmetric cointegration — The relationship may only hold in one direction or one regime. Consider threshold cointegration models for production use.

# Cointegration Analysis
Cointegration testing identifies pairs of assets that share a long-run equilibrium
relationship, enabling statistical arbitrage and pairs trading strategies.
## What Is Cointegration?
Two price series are **cointegrated** when they are individually non-stationary
(random walks) but a linear combination of them is stationary (mean-reverting).
Intuitively, the prices may wander apart temporarily but are pulled back to an
equilibrium spread over time.
### Cointegration vs Correlation
| Property | Correlation | Cointegration |
|---|---|---|
| Measures | Short-term co-movement | Long-run equilibrium |
| Stationarity | Requires stationary returns | Works with non-stationary prices |
| Time horizon | Can change rapidly | Stable over months/years |
| Trading use | Momentum/trend signals | Mean-reversion pairs trades |
| Failure mode | Breaks in regime changes | Breaks on structural shifts |
Two assets can be highly correlated but not cointegrated (e.g., two unrelated
uptrends). Conversely, cointegrated assets may have low short-term correlation
during temporary divergences — which is exactly when pairs trades are entered.
### Why It Matters
- **Pairs trading**: Long the underperformer, short the outperformer, profit on convergence

**Important**: Engle-Granger critical values differ from standard ADF critical
values. For n=2 series: 1% = -3.90, 5% = -3.34, 10% = -3.04.
**Asymmetry warning**: Testing Y~X can give a different result than X~Y. Always
test both directions and use the stronger result.

hedge_ratio = slope
# Step 2: Test residuals
residuals = y_prices - hedge_ratio * x_prices - intercept
adf_stat, p_value, _, _, crit_values, _ = adfuller(residuals, maxlag=None, autolag="AIC")
cointegrated = p_value < 0.05
```
### 2. Johansen Test
