For most companies stock value is meaningless in terms of achieving things. It doesn't put more money in their pocket to pursue development unless they do additional stock offering, which is very unusual for a mature company.
That's not true: from my understanding equity compensation plans fit in here, and that's the vast majority of companies (or really nearly all of them, at least for executive staff).
IF comp is tied to revenue, it doesn't matter if the stock goes to the moon.
The stock goes up because investors think that revenue will go up if they pay fewer salaries.
