So what

Investors are becoming more optimistic that Activision will dominate sales charts during the upcoming holiday season. EA had to delay its Battlefield V release last month, which means Activision's newest Call of Duty: Black Ops title will face a less competitive market in the critical weeks leading up to Black Friday. The video game developer also appears to have a strong contender in the battle royale genre that's set to release in the next few weeks.

Now what

A big launch for Call of Duty: Black Ops 4 might lift Activision's results above the 2018 outlook that CEO Bobby Kotick and his executive team issued in early August. Beyond that, shareholders are looking forward to continued growth in sales and profits as Activision bolsters its deep portfolio of gaming franchises while benefiting from the digital spending shift that's turning video games into recurring revenue generators.
