SunTrust analyst Andrew Jeffrey recommends holding shares of Vantiv (VNTV) on any weakness surrounding a negative report highlighting the company's pricing practices. The analyst recommends adding to positions in Global Payments (GPN) and First Data (FDC). Vantiv and its Mercury unit have been aggressive on pricing, but the practices are tied to value-added technology, not an effort to confuse merchants, Jeffrey tells investors in a research note. The analyst also feels the accusations are "impossible to substantiate." He adds that Global Payments and First Data have not pursued pricing practices similar to Vantiv/Mercury. Jeffrey has a Hold rating on Vantiv. The shares are down 3% to $63.21 after Capitol Forum questioned the company's "deceptive" billings practices.
