PPG Industries Inc. vs RPM International Inc.
WatchlistPPG / RPMPrices through Oct 22, 2026
Why these are rivals: #1 and #2 by market value ($24B vs $13B) in Nasdaq's "Paints/Coatings" industry; SEC SIC 2851 / 2851 (same major group); #1 and #2 by market value ($24B vs $13B) with SEC SIC 2851 (Paints, Varnishes, Lacquers, Enamels & Allied Prods).
Rivals, but right now the price gap does not have a measured habit of closing, so there is no paper idea, whatever the gap.
