Arcelor Mittal NY Registry Shares NEW vs Steel Dynamics Inc.

WatchlistMT / STLDPrices through Oct 22, 2026

Why these are rivals: #2 and #3 by market value ($48B vs $35B) in Nasdaq's "Steel/Iron Ore" industry; SEC SIC 3312 / 3312 (same major group); #2 and #3 by market value ($48B vs $35B) with SEC SIC 3312 (Steel Works, Blast Furnaces & Rolling Mills (Coke Ovens)).

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