Amer Sports Inc. vs lululemon athletica inc.
Why these are rivals: #2 and #3 by market value ($17B vs $10B) in Nasdaq's "Apparel" industry; SEC SIC 2300 / 2300 (same major group); #1 and #2 by market value ($17B vs $10B) with SEC SIC 2300 (Apparel & Other Finishd Prods of Fabrics & Similar Matl).
Rivals, but right now the price gap does not have a measured habit of closing, so there is no paper idea, whatever the gap.
