How correlated are CRL and WMT?
Over the past 3 years, CRL and WMT moved with a correlation of -0.22, which is negative, meaning they tend to move in opposite directions. The relationship has been stable: the 1-year correlation (-0.20) sits close to the 3-year figure. Over 5 years the correlation is -0.01, and the annualized covariance of weekly returns is -237.2 %².
Out of 33 assets tracked against CRL, WMT lands near the bottom at #30. Correlation aside, the last 12 months split them widely, with CRL ahead by 74.4 points (+82.1% versus +7.7%). Do not treat this figure as fixed: across three years the rolling one-year correlation ranged all the way from -0.33 to 0.31. Note the risk asymmetry: CRL runs 2.1 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.
