Aptiv looks cheap against its earnings at about 7x next year's, while auto-parts suppliers usually get 11x. Applying 11x to mid-cycle EPS of $6.60, give or take 12%, puts fair value at $63.92 to $81.35, leaving $44.79 about 30% below the low end. Trailing and forward earnings differ by 196%, so the range is wide, and this is a valuation read only, not fundamental work. x.com
