Wells Fargo analyst Philip Winslow raised his price target for Tableau Software to $90 saying the company reported "strong" Q4 results with revenue, operating income, and earnings above consensus expectations. While the Q1 and fiscal 2018 revenue guidance came in above consensus, operating income and earnings guidance were below consensus as Tableau continues to add headcount, Winslow tells investors in a post-earnings research note. He keeps a Market Perform rating on the stock. Continued slow growth in perpetual license equivalent value and competitive headwinds keep us on the sidelines, Winslow writes.
