How correlated are RTX and XLI?
On 3 years of weekly data the RTX/XLI correlation comes out at 0.49, moderate. Little has changed lately, as the 1-year reading of 0.51 lands near the 3-year figure. The 5-year figure is 0.53, and annualized covariance runs at 193.8 %².
By 3-year correlation, XLI places #7 of the 27 assets tracked against RTX. Their recent paths diverged sharply: over the last 12 months RTX outperformed by 16.4 percentage points (+34.7% for RTX against +18.3% for XLI). Do not treat this figure as fixed: across three years the rolling one-year correlation ranged all the way from 0.16 to 0.67. Note the risk asymmetry: RTX runs 1.6 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.
