IDEX Corporation vs ITT Inc.

WatchlistIEX / ITTPrices through Oct 22, 2026

Why these are rivals: #2 and #3 by market value ($18B vs $17B) in Nasdaq's "Fluid Controls" industry; SEC SIC 3561 / 3561 (same major group); #2 and #3 by market value ($18B vs $17B) with SEC SIC 3561 (Pumps & Pumping Equipment).

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