Stifel analyst Brad Reback upgraded Teradata to Buy from Hold and raised his price target for the shares to $49 from $45. The current valuation creates a risk/reward scenario that is "too compelling to ignore," Reback tells investors in a research note. Teradata's recent strategic moves, including decoupling its software from pre-configured hardware and offering a subscription pricing option, has re-engage the company with its installed base and driven "healthy" recurring revenue growth, the analyst adds. He believes the worst is behind the company and that Teradata should meet its 12% recurring revenue growth target for 2018. As such, the stock "could post meaningful multiple expansion in coming quarters," Reback argues.
