Please provide a link to the world of warcraft stock on the stock exchange. No one is bossing you around, you are evading the question and answering something no one asked. Your logic completely falls apart when you consider there is no wow stock. Wow could shut down and the stock could still gain value due to other products, other releases, the reduced operational costs increasing profits, etc.
You also fail to understand that stocks are impacted to a far greater degree by external factors. So the stocks could dramatically change without wow or any of the many other games under the same umbrella being a factor at all.
