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.

Market Update

In response to the Fed’s rate hikes in 2022 and 2023, inflation has been gradually trending down from its post-pandemic peak, trending closer to the Fed’s 2% target. Despite higher borrowing costs, the economy has avoided flashing recessionary signals. This is the much-desired soft landing that many investors hoped for. The recent rate cuts (0.5% in September and 0.25% in November 2024) have bolstered the stock market, making 2024 a strong year for equities.
