O’Reilly Automotive (NASDAQ: ORLY) is a retailer specializing in auto parts, which, despite its seemingly mundane business model, has seen remarkable growth; a $10,000 investment at the turn of the century has grown to over $1.2 million today. The company’s growth strategy mirrors that of typical retailers, focusing on increasing sales from existing stores, expanding its store locations, or a combination of both. This raises the intriguing question of whether investing $10,000 in O’Reilly Automotive now could similarly yield millionaire status in the future.
