Correlation aside, the last 12 months split them widely, with APA ahead by 91.6 points (+94.1% versus +2.5%). The relationship is regime-dependent: the rolling one-year correlation swung between -0.50 and 0.08 over the past three years, so this pair behaves very differently depending on the market environment. One caveat on sizing: APA is 26.1 times as volatile as the other leg, so an equal-dollar split is far from equal-risk.
