Goldman Sachs analyst Robert Jones added Iqvia Holdings (IQ) to his firm's Americas Conviction List while keeping a Buy rating on the shares. The analyst lowered his price target for the shares to $151 from $152. He sees "several drivers of upside" in 2019 against a "very healthy" industry backdrop. Iqvia's backlog growth along with an industry leading book-to-bill indicate its offering is resonating in the market, Jones tells investors in a research note. He believes the company's upcoming commentary accompanying 2019 guidance could serve as a potential catalyst for the shares. Jones is also positive on shares of Icon (ICLR).
