Let’s dig into the relative performance of Advanced Drainage (NYSE:WMS) and its peers as we unravel the now-completed Q3 hvac and water systems earnings season.

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

As a result of the Fed’s rate hikes in 2022 and 2023, inflation has come down from frothy levels post-pandemic. The general rise in the price of goods and services is trending towards the Fed’s 2% goal as of late, which is good news. The higher rates that fought inflation also didn't slow economic activity enough to catalyze a recession. So far, soft landing. This, combined with recent rate cuts (half a percent in September 2024 and a quarter percent in November 2024) have led to strong stock market performance in 2024. The icing on the cake for 2024 returns was Donald Trump’s victory in the U.S. Presidential Election in early November, sending major indices to all-time highs in the week following the election. Still, debates around the health of the economy and the impact of potential tariffs and corporate tax cuts remain, leaving much uncertainty around 2025.
