CVS Health shares jumped higher than broader indexes. More recently, CVS health has started opening stores it calls “HealthHubs” that have dietitians and are geared toward helping customers monitor chronic conditions like diabetes and stay on top of their health. She came to CVS Health when Aetna was acquired and served as an executive with another insurer, Cigna, before that. CVS Health will become the largest company in that group, topping General Motors, which is led by Mary Barra. CVS Health Corp., based in Woonsocket, Rhode Island, runs one of the nation’s largest drugstore chains with about 9,900 retail locations.
