The relationship is regime-dependent: the rolling one-year correlation swung between 0.22 and 0.83 over the past three years, so this pair behaves very differently depending on the market environment. One caveat on sizing: CSCO is 1.8 times as volatile as the other leg, so an equal-dollar split is far from equal-risk.
