How correlated are RIO and SCCO?
On 3 years of weekly data the RIO/SCCO correlation comes out at 0.70, strong. Little has changed lately, as the 1-year reading of 0.71 lands near the 3-year figure. The 5-year figure is 0.74, and annualized covariance runs at 719.6 %².
Few assets follow RIO as closely as SCCO, which ranks #1 of 19 tracked partners. The last year tells two different stories: SCCO led by 57.3 percentage points, +77.2% for RIO against +134.5% for SCCO. One caveat on sizing: SCCO is 1.6 times as volatile as the other leg, so an equal-dollar split is far from equal-risk.
