DexCom Stock Just Fell to a 5-Year Low. Is It a No-Brainer Buy at This Price?

Core Viewpoint - DexCom's stock has declined by 25% since the beginning of 2025, despite a generally positive stock market environment, raising questions about its future performance and potential buying opportunities [1][2]. Financial Performance - DexCom reported third-quarter earnings on October 30, with revenue of $1.2 billion, reflecting a year-over-year increase of 22%. However, this growth is compared to a period of slow growth last year, leading to skepticism among investors regarding its sustainability [4]. Market Concerns - Investors are increasingly bearish on DexCom due to the emergence of GLP-1 weight loss drugs, which may reduce the demand for continuous glucose monitoring (CGM) devices. These drugs have shown effectiveness in lowering glucose levels for diabetes patients, potentially impacting DexCom's market [5][6]. Stock Valuation - DexCom's stock is currently trading at levels not seen since the COVID-19 crash of 2020, with a forward price-to-earnings (P/E) multiple of 26, which is lower than its historical average. This situation may present a buying opportunity for investors [7][8].
