How correlated are A and SPKL?

On 3 years of weekly data the A/SPKL correlation comes out at -0.15, negative, meaning they tend to move in opposite directions. Little has changed lately, as the 1-year reading of -0.21 lands near the 3-year figure. The 5-year figure is n/a, and annualized covariance runs at -55.0 %².

By 3-year correlation, SPKL places #24 of the 33 assets tracked against A. Correlation aside, the last 12 months split them widely, with A ahead by 28.4 points (+33.9% versus +5.5%). One caveat on sizing: A is 2.6 times as volatile as the other leg, so an equal-dollar split is far from equal-risk.

How is this computed?

Pearson correlation on weekly returns: ρ(A,B) = cov(rA, rB) / (σA · σB), over windows of 52, 156 and 260 weeks. Covariance is annualized (×52) and expressed in %². Full definitions on the methodology page.
