Industry is irrelevant. My point when using them as an example was the fact that on an analytical data driven evaluation, they were WAY over rated @ $240.00 And even now some would argue, still way over rated. Why are their share prices so high? Because people have taken an emotional stance that this they will succeed.
My point is that with ANY stock, hype and emotion are huge drivers when it comes to value.. Isn't hype going to trigger an emotion? Isn't it hype that is used as part of the pump in a pump and dump?
People get their emotions caught up in any stock that represents any industry, regardless of the number of competitors. It's money. To say that people don't simply isn't true.
