What’s the difference between correlation and cointegration?
Correlation measures whether two assets’ daily returns move together. Cointegration asks something stronger: whether the gap between their prices — their ratio — is tethered and tends to pull back toward its usual level. Two assets can be highly correlated yet drift apart for months; that is correlation without cointegration.
