EMCOR Group Inc. vs Comfort Systems USA Inc.
WatchlistEME / FIXPrices through Nov 10, 2026
Why these are rivals: #2 and #3 by market value ($45B vs $31B) in Nasdaq's "Engineering & Construction" industry; SEC SIC 1731 / 1731 (same major group); #2 and #3 by market value ($45B vs $31B) with SEC SIC 1731 (Electrical Work).
Rivals, but right now the price gap does not have a measured habit of closing, so there is no paper idea, whatever the gap.
