Rolling Correlations
Correlations are not static — assets that usually diversify can move together in a crisis. Track how each pair's correlation has shifted over time, and watch the average pairwise correlation as a gauge of how much real diversification your basket provides.

What is the Rolling Correlations?
Correlations aren't constant — track how each pair's relationship has evolved, plus the basket's average correlation.
A pair of assets that usually diversifies can suddenly move together in a crisis — exactly when you need diversification most. The Rolling Correlations tool charts a moving-window correlation for every pair over time and overlays the average pairwise correlation as a gauge of how much real diversification your basket is providing at any moment.

How the Rolling Correlations works
For each window, correlation is recomputed on the returns inside it, producing a time series. The average line aggregates all pairs to show whole-portfolio diversification over time.
