Nomura Instinet analyst Andrew Marok upgraded Activision Blizzard to Buy from Neutral and raised his price target for the shares to $64 from $49. The game maker closed yesterday down $1.12 to $54.91. Last month's launch of World of Warcraft Classic has driven "strong, above-expectations" engagement in the franchise, Marok tells investors in a research note. Further, Overwatch has recently added new features and last week announced a launch on the Nintendo Switch, the analyst points out. He believes these provides a "much more favorable backdrop" heading into November's BlizzCon, where he expects Activision will see the reveal of a World of Warcraft expansion for 2020 release and at least one of Diablo 4 or Overwatch 2.
