How correlated are CRM and SO?

Over the past 3 years, CRM and SO moved with a correlation of -0.23, which is negative, meaning they tend to move in opposite directions. Recent behaviour matches the longer record: -0.24 over 1 year against -0.23 over 3. Over 5 years the correlation is -0.04, and the annualized covariance of weekly returns is -140.2 %².

By 3-year correlation, SO places #60 of the 68 assets tracked against CRM. Neither side won the trailing year by much: +1.6% against -1.4%. Do not treat this figure as fixed: across three years the rolling one-year correlation ranged all the way from -0.45 to 0.21. One caveat on sizing: CRM is 2.3 times as volatile as the other leg, so an equal-dollar split is far from equal-risk.
