ResMed's GLP-1 selloff reflects a temporary fear that misreads the business. Sleep apnea affects hundreds of millions of mostly undiagnosed people, leaving decades of growth even with weight-loss drugs, and people on these drugs get diagnosed faster because they see doctors more. ResMed has a wide moat in a near-duopoly with Philips, which lost share after its recalls, high and stable margins and ROIC, and sticky software. A long-term compounder at a very reasonable valuation. x.comÂ
