This Market-Beating Auto Stock Just Raised Its Full-Year 2021 Outlook

O'Reilly Automotive (NASDAQ: ORLY), the largest domestic chain by market capitalization, just reported stellar first-quarter 2021 results on April 28th, demonstrating continued strength in the business even as the country slowly moves past the health crisis. At the same time, management raised same-store sales (comps) and diluted earnings per share (EPS) forecasts for the full year 2021. Mind you, the company had an easy year-over-year comparison, but sales did eclipse $3 billion, which was on par with the impressive second and third quarters of 2020.
