Examples include the auto parts retailers like O'Reilly Automotive (NASDAQ: ORLY), AutoZone (NYSE: AZO), and Advance Auto Parts (NYSE: AAP). Throw in low gasoline prices encouraging drivers to rack up mileage and ongoing air travel restrictions, and the outlook is good for the auto parts retailers. For example, food safety, clean water, and hygiene company Ecolab (NYSE: ECL) has an opportunity to benefit due to its market leadership in sanitation.
