Amazon.com Inc. vs CDW Corporation

WatchlistAMZN / CDWPrices through Oct 22, 2026

Why these are rivals: #1 and #3 by market value ($2831B vs $19B) in Nasdaq's "Catalog/Specialty Distribution" industry; SEC SIC 5961 / 5961 (same major group); #1 and #3 by market value ($2831B vs $19B) with SEC SIC 5961 (Retail-Catalog & Mail-Order Houses).

Rivals, but right now the price gap does not have a measured habit of closing, so there is no paper idea, whatever the gap.
