1 Reason I Haven't Bought Costco Stock -- and Probably Never Will

Core Viewpoint - Costco's strong performance and high-quality offerings have led to a premium valuation, making it less attractive for new investors despite its success in the retail sector [1][9]. Group 1: Company Performance - Costco operates successfully across four continents, avoiding cultural pitfalls that have affected competitors like Walmart and Home Depot [2]. - In the first quarter of fiscal 2026, Costco reported total revenue of $67 billion, reflecting an 8% growth, with net income reaching $2 billion, an 11% increase [6]. Group 2: Valuation Concerns - The company's current P/E ratio stands at approximately 54, significantly higher than Walmart's 45 and Amazon's 28, raising concerns about its valuation relative to growth [4]. - Despite its consistent execution and avoidance of major missteps, Costco's profit growth remains in the low double-digit percentage range, which does not justify its high valuation [7]. Group 3: Investment Outlook - Costco's P/E ratio has not dipped below 30 since 2019, and it last fell below 20 in 2010, indicating that a more attractive valuation for new investors may be a long wait [8]. - Given its premium valuation and moderate growth, Costco is considered a high-quality stock that may not be suitable for new investors seeking better value opportunities [10].
