How correlated are APTV and MAR?
On 3 years of weekly data the APTV/MAR correlation comes out at 0.36, moderate. Recent behaviour matches the longer record: 0.45 over 1 year against 0.36 over 3. The 5-year figure is 0.48, and annualized covariance runs at 332.8 %².
Within APTV's tracked universe of 33 assets, MAR comes in at #18 by 3-year correlation. Correlation aside, the last 12 months split them widely, with MAR ahead by 75.5 points (-43.2% versus +32.3%). The relationship is regime-dependent: the rolling one-year correlation swung between 0.06 and 0.57 over the past three years, so this pair behaves very differently depending on the market environment. Note the risk asymmetry: APTV runs 1.5 times the annualized volatility of the other leg, so equal-weighting the two is not an equal-risk position.
