Correlation Analysis

Cross-asset correlation analysis for diversification assessment, risk management, pairs trading signal generation, and portfolio construction.

Why Correlation Matters

Correlation measures how assets move together. In crypto markets this is critical for:

Diversification: holding correlated assets provides no diversification benefit — you are effectively holding one concentrated position
Risk management: portfolio risk depends on the correlation structure, not just individual asset volatility
Pairs trading: highly correlated assets that temporarily diverge create mean-reversion opportunities
Portfolio construction: optimal allocation requires accurate correlation estimates
Crash protection: understanding tail dependence reveals whether assets crash together

Correlation Methods

Pearson Correlation

Linear correlation assuming normality. Most common but least robust for crypto.

import pandas as pd
import numpy as np

# Always compute on returns, never on prices
returns_a = prices_a.pct_change().dropna()
returns_b = prices_b.pct_change().dropna()

pearson_corr = returns_a.corr(returns_b)  # default is Pearson

Range: -1 (perfect inverse) to +1 (perfect co-movement)
Assumes: linear relationship, normally distributed returns, no outliers
Limitation: crypto returns are heavy-tailed — Pearson underestimates extreme co-movement

Spearman Rank Correlation

Converts values to ranks, then computes Pearson on ranks. Captures monotonic (not just linear) relationships.

spearman_corr = returns_a.corr(returns_b, method='spearman')

More robust to outliers and non-linear relationships
Better for crypto due to heavy-tailed return distributions
Slightly lower power than Pearson when normality holds

Kendall Tau Correlation

Counts concordant vs discordant pairs. Most robust to outliers.

kendall_corr = returns_a.corr(returns_b, method='kendall')

Most robust to outliers of the three methods
Computationally slower on large datasets
Best for small samples or heavily skewed data

Rolling Correlation

Static correlation hides regime changes. Rolling correlation reveals how relationships evolve.

Window-Based Rolling Correlation

# Rolling Pearson correlation
rolling_corr = returns_a.rolling(window=60).corr(returns_b)

# Multiple windows for different time horizons
windows = {
    'short': 20,    # ~1 month of trading days
    'medium': 60,   # ~3 months
    'long': 120,    # ~6 months
}
for label, w in windows.items():
    df[f'corr_{label}'] = returns_a.rolling(w).corr(returns_b)

EWMA Correlation

Exponentially weighted — more responsive to recent changes.

def ewma_correlation(x: pd.Series, y: pd.Series, span: int = 60) -> pd.Series:
    """Compute EWMA correlation between two return series."""
    cov_xy = x.mul(y).ewm(span=span).mean() - x.ewm(span=span).mean() * y.ewm(span=span).mean()
    std_x = x.ewm(span=span).std()
    std_y = y.ewm(span=span).std()
    return cov_xy / (std_x * std_y)

Typical Windows

Window	Days	Use Case
Short	20	Tactical trading, pairs entry/exit
Medium	60	Strategy allocation, regime detection
Long	120	Portfolio construction, strategic allocation

Correlation Matrix Analysis

Computing the Full Matrix

# Build return matrix for multiple assets
returns = pd.DataFrame({
    'BTC': btc_returns,
    'ETH': eth_returns,
    'SOL': sol_returns,
    'AVAX': avax_returns,
})

# Correlation matrix (Pearson)
corr_matrix = returns.corr()

# Spearman (better for crypto)
spearman_matrix = returns.corr(method='spearman')

Eigenvalue Decomposition

Decompose the correlation matrix to identify driving factors.

eigenvalues, eigenvectors = np.linalg.eigh(corr_matrix.values)

# Sort descending
idx = eigenvalues.argsort()[::-1]
eigenvalues = eigenvalues[idx]
eigenvectors = eigenvectors[:, idx]

# First eigenvalue = market factor (explains most variance)
# Subsequent eigenvalues = sector/style factors
market_factor_pct = eigenvalues[0] / eigenvalues.sum() * 100

First eigenvector: the market factor — when this dominates (>60% variance), everything moves together
Subsequent eigenvectors: sector or style factors
Small eigenvalues: noise / idiosyncratic risk

Minimum Variance Portfolio

from numpy.linalg import inv

cov_matrix = returns.cov()
ones = np.ones(len(cov_matrix))
inv_cov = inv(cov_matrix.values)

# Minimum variance weights
weights = inv_cov @ ones / (ones @ inv_cov @ ones)

Hierarchical Clustering

Group assets by correlation similarity to identify natural clusters.

from scipy.cluster.hierarchy import linkage, fcluster
from scipy.spatial.distance import squareform

# Convert correlation to distance
dist_matrix = np.sqrt(2 * (1 - corr_matrix.values))
np.fill_diagonal(dist_matrix, 0)

# Hierarchical clustering
condensed = squareform(dist_matrix)
linkage_matrix = linkage(condensed, method='ward')

# Cut at threshold to get clusters
clusters = fcluster(linkage_matrix, t=1.0, criterion='distance')

Applications:

Sector detection: assets in the same cluster behave similarly
Diversification: select one asset per cluster for maximum diversification
Risk allocation: allocate risk budget across clusters, not individual assets

Tail Dependence

Normal correlation understates co-movement during crashes. Tail dependence measures how often assets experience extreme returns simultaneously.

Lower Tail Dependence

def tail_dependence(x: pd.Series, y: pd.Series, quantile: float = 0.05) -> float:
    """Estimate lower tail dependence coefficient.

    Measures P(Y < q | X < q) for quantile q.
    Higher values mean assets crash together more often.
    """
    threshold_x = x.quantile(quantile)
    threshold_y = y.quantile(quantile)
    joint_extreme = ((x < threshold_x) & (y < threshold_y)).sum()
    marginal_extreme = (x < threshold_x).sum()
    return joint_extreme / marginal_extreme if marginal_extreme > 0 else 0.0

Crypto-Specific Tail Behavior

In crypto markets, tail dependence typically exceeds normal correlation:

Normal correlation of 0.6 between two altcoins might have tail dependence of 0.8
During market panics, correlations spike toward 1.0 across all risk assets
This means diversification benefits disappear exactly when needed most

Regime-Dependent Correlation

Correlation is not constant — it changes with market regime.

Regime	Typical Correlation	Implication
Bull (trending up)	0.4–0.7	Moderate — some diversification works
Range-bound	0.2–0.5	Lower — best diversification environment
Bear (crash)	0.8–0.95	Very high — diversification fails
Recovery	0.5–0.7	Declining from crash highs

Detecting Correlation Regime Shifts

def correlation_zscore(rolling_corr: pd.Series, lookback: int = 252) -> pd.Series:
    """Z-score of rolling correlation vs its own history."""
    mean = rolling_corr.rolling(lookback).mean()
    std = rolling_corr.rolling(lookback).std()
    return (rolling_corr - mean) / std

# Flag regime shift when z-score exceeds threshold
zscore = correlation_zscore(rolling_corr_60d)
regime_shift = zscore.abs() > 2.0

Crypto-Specific Correlation Patterns

Typical Correlation Ranges

Pair	Normal Range	Notes
BTC / ETH	0.7–0.9	Highest among majors
BTC / SOL	0.6–0.85	SOL more volatile, slightly less correlated
BTC / Altcoin	0.5–0.8	Varies by market cap and sector
Meme / BTC	0.2–0.5	Lower normal correlation
Meme / Meme	0.1–0.4	Low normal but high tail dependence
Stablecoin / BTC	-0.1–0.1	Should be near zero

Key Observations

Most altcoins are highly correlated with BTC (0.6–0.9) — the market factor dominates
Meme and PumpFun tokens show lower normal correlation but higher tail dependence
SOL ecosystem tokens correlate strongly with SOL price
Stablecoins should be uncorrelated with risk assets — if correlation appears, investigate (depeg risk)
Correlation tends to increase during high-volatility regimes
New token launches may show temporarily low correlation until price discovery stabilizes

Integration with Other Skills

risk-management: use correlation to compute portfolio-level VaR and stress scenarios
portfolio-analytics: correlation matrix feeds optimal allocation algorithms
regime-detection: correlation regime shifts are an input to regime classification
cointegration-analysis: pairs with high correlation are candidates for cointegration testing
position-sizing: correlation-adjusted sizing prevents correlated concentration
