What the Number Means

With a correlation of -0.19, Energy (XLE) and Financials (XLF) are essentially uncorrelated at daily frequency. Either the relationship operates at a different time horizon or the shared driver has been dominated by idiosyncratic noise during the observation window.

Recent vs Long-Run Behavior

Last 90 Days
-0.185
5-Year Baseline
+0.494

The historical positive relationship between Energy (XLE) and Financials (XLF) has inverted. Recent 90-day correlation is -0.19 versus a long-run reading of 0.49. 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 Financials (XLF) returns. A beta above 1 means the first asset amplifies moves of the second.

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 Financials (XLF), 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.
