How correlated are CRF and ETB?
On 3 years of weekly data the CRF/ETB correlation comes out at 0.67, strong. Little has changed lately, as the 1-year reading of 0.58 lands near the 3-year figure. The 5-year figure is 0.49, and annualized covariance runs at 199.7 %².
In CRF's tracked universe of 12 assets, ETB sits right near the top at #3. Their recent paths diverged sharply: over the last 12 months ETB outperformed by 15.9 percentage points (-1.7% for CRF against +14.2% for ETB). One caveat on sizing: CRF is 1.5 times as volatile as the other leg, so an equal-dollar split is far from equal-risk.
