Understanding Correlations

Correlation (-1 to +1)

Measures how closely two securities move together. +1 means perfect positive correlation, -1 means perfect inverse, 0 means no relationship.

Stability (0 to 1)

How consistent the correlation has been over time. Higher stability means more reliable, lower means the relationship is erratic.

Adjusted Score

Correlation × Stability. This penalizes unstable correlations - a 0.8 correlation with 0.5 stability is less useful than 0.6 correlation with 0.9 stability.

Regimes

Index-Tracker: Moves closely with indices. Partial: Some index influence. Independent: Marches to its own drum.
