How correlated are CET and VXX?
On 3 years of weekly data the CET/VXX correlation comes out at -0.73, negative, meaning they tend to move in opposite directions. Little has changed lately, as the 1-year reading of -0.68 lands near the 3-year figure. The 5-year figure is -0.63, and annualized covariance runs at -568.2 %².
VXX is close to the least connected end of CET's tracked universe, ranking #38 of 38. The last year tells two different stories: CET led by 65.4 percentage points, +15.7% for CET against -49.7% for VXX. One caveat on sizing: VXX is 4.8 times as volatile as the other leg, so an equal-dollar split is far from equal-risk.
