Comfort Systems (NYSE:FIX) joins the S&P 500 index after quarterly rebalancing on December 5. This change will be effective before the market opens on December 22, replacing LKQ Corp., Mohawk Industries Inc., and Solstice Advanced Materials Inc.

Matt Maley, chief market strategist at Miller Tabak + Co., notes Comfort Systems stock tends to rise leading up to the S&P inclusion. Positive momentum since April dip expected to continue despite potential post-inclusion interest drop.

After an earnings beat in Q3 and upgrades from UBS and Stifel, FIX maintains a consensus buy rating with a 15.21% upside from current levels. The company, founded in 1917, provides mechanical and electrical services, including ventilation, air conditioning, and heating systems.
