The end of an earnings season can be a great time to discover new stocks and assess how companies are handling the current business environment. Let’s take a look at how Onterris (NYSE: ONT) and the rest of the waste management stocks fared in Q2.

Waste management companies can possess licenses permitting them to handle hazardous materials. Furthermore, many services are performed through contracts and statutorily mandated, non-discretionary, or recurring, leading to more predictable revenue streams. However, regulation can be a headwind, rendering existing services obsolete or forcing companies to invest precious capital to comply with new, more environmentally-friendly rules. Lastly, waste management companies are at the whim of economic cycles. Interest rates, for example, can greatly impact industrial production or commercial projects that create waste and byproducts.

Market Update

Over the past year, investors have been forced to repeatedly answer the same question: what is the market’s biggest risk? The answer has changed several times, and each shift has reshaped market leadership.

Late in 2025 and early 2026, artificial intelligence became the market’s primary uncertainty. Investors questioned whether AI would erode software pricing power and weaken competitive moats as AI made it easier to replicate once-differentiated products.

By the spring, technology took a back seat to geopolitics. The U.S. conflict with Iran briefly became the market’s dominant narrative, raising concerns about oil prices, inflation, and global growth. But as energy markets remained orderly and fears of a prolonged supply disruption faded, investors quickly turned their focus back to fundamentals.
