What the Number Means

A correlation of 0.38 signals only a weak tendency to move together. 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
+0.382
5-Year Baseline
+0.287

Recent correlation tracks the long-run relationship closely. No meaningful divergence. The historical pattern between Real Estate (XLRE) and 20Y+ Treasury (TLT) is intact and should continue to serve as a reasonable baseline for positioning.

Observations252

Correlation measures directional co-movement; R² quantifies the fraction of variance explained by the linear relationship. Beta is the slope coefficient from regressing Real Estate (XLRE) returns on 20Y+ Treasury (TLT) 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 Real Estate (XLRE) and 20Y+ Treasury (TLT), 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.
