By 3-year correlation, VRT places #7 of the 33 assets tracked against PWR. The last year tells two different stories: VRT led by 45.4 percentage points, +63.1% for PWR against +108.5% for VRT. The relationship is regime-dependent: the rolling one-year correlation swung between 0.27 and 0.83 over the past three years, so this pair behaves very differently depending on the market environment. One caveat on sizing: VRT is 1.7 times as volatile as the other leg, so an equal-dollar split is far from equal-risk.
