The end of the earnings season is always a good time to take a step back and see who shined (and who not so much). Let’s take a look at how hvac and water systems stocks fared in Q2, starting with Trane Technologies (NYSE: TT).
Many HVAC and water systems companies sell essential, non-discretionary infrastructure for buildings. Since the useful lives of these water heaters and vents are fairly standard, these companies have a portion of predictable replacement revenue. In the last decade, trends in energy efficiency and clean water are driving innovation that is leading to incremental demand. On the other hand, new installations for these companies are at the whim of residential and commercial construction volumes, which tend to be cyclical and can be impacted heavily by economic factors such as interest rates.
