Can somebody help explain why Activision Blizzard (ATVI) is struggling this week? Down 1.5% when it seems as though it should be trending up

I’m relatively new to investing and own 4 shares of ATVI (big bucks, I know). I was under the understanding that the Microsoft FTC trial last week had played out well for Microsoft and Activision, pending Judge Corley’s final ruling. On top of that, Diablo IV (a live service game based in longevity) was announced as the fastest selling Blizzard game of all time and has surely passed $1bn in sales ($666m was announced within the first week of release). Their quarterly earnings report is due by the 31st of this month and I’m confident that Diablo pre-orders and sales will reflect on that. So why has the movement on share prices only gone down this week? Any insight would be appreciated, I am seeking education on the topic more than anything. Thanks for taking the time to read.
