Looking back on patient monitoring stocks’ Q3 earnings, we examine this quarter’s best and worst performers, including DexCom (NASDAQ: DXCM) and its peers.
Patient monitoring companies within the healthcare equipment industry offer devices and technologies that track chronic conditions and support real-time health management, such as continuous glucose monitors (CGMs) and sleep apnea machines. These businesses benefit from recurring revenue from consumables and software subscriptions tied to device sales (razor, razor blade model). The rising prevalence of chronic diseases like diabetes and respiratory disorders due to an aging population as well as growing adoption of digitization are good for the industry. However, these companies face challenges from high R&D costs and reliance on regulatory approvals. Looking ahead, the sector is positioned for growth due to tailwinds like the rising burden of chronic diseases from an aging population, the shift toward value-based care, and increased adoption of digital health solutions. Innovations in AI and machine learning are expected to enhance device accuracy and functionality, improving patient outcomes and driving demand. However, there are headwinds such as pricing pressures as healthcare costs are a key focus, especially in the US. An evolving regulatory landscape and competition from more tech-forward new entrants could present additional challenges.

Market Update
Thanks to the Fed’s series of rate hikes in 2022 and 2023, inflation has cooled significantly from its post-pandemic highs, drawing closer to the 2% goal. This disinflation has occurred without severely impacting economic growth, suggesting the success of a soft landing. The stock market thrived in 2024, spurred by recent rate cuts (0.5% in September and 0.25% in November), and a notable surge followed Donald Trump’s presidential election win in November, propelling indices to historic highs. Nonetheless, the outlook for 2025 remains clouded by potential trade policy changes and corporate tax discussions, which could impact business confidence and growth. The path forward holds both optimism and caution as new policies take shape.
