3M Company vs Stryker Corporation

WatchlistMMM / SYKPrices through Oct 22, 2026

Why these are rivals: #1 and #2 by market value ($114B vs $84B) in Nasdaq's "Medical/Dental Instruments" industry; SEC SIC 3841 / 3841 (same major group); #1 and #2 by market value ($114B vs $84B) with SEC SIC 3841 (Surgical & Medical Instruments & Apparatus).

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