JPMorgan analyst Mark Murphy raised his price target for Tableau Software to $140 and keeps an Overweight rating on the shares. Tableau entering a period of more stable growth and reported a good Q4, exceeding revenue and earnings estimates, Murphy tells investors in a research note. The analyst points out that the stock is already up 11% year-to-date on top of a 73% return in 2018. While the stock is susceptible to short-term profit taking, what's significant is Tableau reaffirming 2019 revenue guidance with an incremental point of pro forma operating margin, says the analyst.
