What the Number Means

A correlation of -0.24 signals only a weak tendency to move in opposite directions. On most days the two move independently. Do not expect one to reliably predict the other. Look for conditional relationships within specific regimes or event windows.

Recent vs Long-Run Behavior

Last 90 Days
-0.243
5-Year Baseline
+0.479

The historical positive relationship between Energy (XLE) and Industrials (XLI) has inverted. Recent 90-day correlation is -0.24 versus a long-run reading of 0.48. This kind of decoupling tends to mark regime transitions. Often one asset is responding to a newly dominant driver while the other is anchored to the old narrative.

Correlation measures directional co-movement; R² quantifies the fraction of variance explained by the linear relationship. Beta is the slope coefficient from regressing Energy (XLE) returns on Industrials (XLI) returns. A beta above 1 means the first asset amplifies moves of the second.

Year-by-year correlation reveals how the relationship has held up across different macro regimes. Sharp year-over-year swings in correlation often mark the transition between stress and calm periods.

Extremes in rolling 90-day correlation often coincide with regime changes, forced deleveraging, or the arrival of a dominant new macro theme that overwhelms normal relationships.

Methodology

Correlations are computed on daily log-adjacent returns for Energy (XLE) and Industrials (XLI), aligned on shared trading dates. We use the Pearson product-moment coefficient, which measures the linear relationship between two return series.

Windows are the most recent N observations for 30D, 90D, and 1Y (252 trading days); the 5Y figure uses all aligned data up to 1,260 observations. Beta is the OLS slope from regressing the first series on the second. Data updates daily with a 24-hour revalidation cadence.

Correlation is not causation and backward-looking statistics can fail when regimes shift. Positions sized on historical correlation assumptions should be stress-tested against scenarios where the relationship breaks. For informational purposes only.
