How correlated are AES and EIX?
On 3 years of weekly data the AES/EIX correlation comes out at 0.37, moderate. Little has changed lately, as the 1-year reading of 0.31 lands near the 3-year figure. The 5-year figure is 0.47, and annualized covariance runs at 389.9 %².
Within AES's tracked universe of 31 assets, EIX comes in at #18 by 3-year correlation. Their recent paths diverged sharply: over the last 12 months EIX outperformed by 24.5 percentage points (+15.9% for AES against +40.4% for EIX). On a rolling one-year basis the correlation drifted between 0.20 and 0.64, a moderate band. Note the risk asymmetry: AES runs 1.6 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.
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.
