The more you believe that the more you should expect the stock price to move on announcements like this one.

I think the other users point was that in the past the prices didn’t move because people assumed that other people knew what was going on (and they were not selling or driving prices down).

Accordingly the price might not move because of similar assumptions.

To be clear that’s just how I read that comment. I know nothing about this situation with Microsoft.
