How correlated are BAX and QQQ?

Over the past 3 years, BAX and QQQ moved with a correlation of 0.21, which is weak. The relationship has been stable: the 1-year correlation (0.18) sits close to the 3-year figure. Over 5 years the correlation is 0.27, and the annualized covariance of weekly returns is 158.3 %².

By 3-year correlation, QQQ places #33 of the 43 assets tracked against BAX. Correlation aside, the last 12 months split them widely, with QQQ ahead by 19.7 points (+6.6% versus +26.3%). The relationship is regime-dependent: the rolling one-year correlation swung between -0.04 and 0.47 over the past three years, so this pair behaves very differently depending on the market environment. One caveat on sizing: BAX is 2.0 times as volatile as the other leg, so an equal-dollar split is far from equal-risk.
