Costco Wholesale Corporation vs Target Corporation
WatchlistCOST / TGTPrices through Oct 22, 2026
Why these are rivals: #2 and #3 by market value ($441B vs $70B) in Nasdaq's "Department/Specialty Retail Stores" industry; SEC SIC 5331 / 5331 (same major group); #2 and #3 by market value ($441B vs $70B) with SEC SIC 5331 (Retail-Variety Stores).
Rivals, but right now the price gap does not have a measured habit of closing, so there is no paper idea, whatever the gap.
