BorgWarner Inc. vs Magna International Inc.
Why these are rivals: #2 and #3 by market value ($17B vs $12B) in Nasdaq's "Auto Parts:O.E.M." industry; SEC SIC 3714 / 3714 (same major group); #1 and #2 by market value ($17B vs $12B) with SEC SIC 3714 (Motor Vehicle Parts & Accessories).
Rivals, but right now the price gap does not have a measured habit of closing, so there is no paper idea, whatever the gap.
- Co-movement: daily return correlation, 252 sessions: 0.47 (needs >= 0.60)
- Mean reversion: ADF t-statistic of the spread: -2.69 (needs <= -2.873 (5% critical value))
