A chief marketing officer (CMO) is the senior executive who leads a company's efforts to attract and keep customers by managing brand image, advertising, pricing signals and market research. Investors monitor the CMO because their strategies directly affect sales growth, customer loyalty and the success of product launches—think of the CMO as the person designing a store’s storefront and promotions to draw and retain shoppers, which impacts revenue and valuation.
