You appear to have a point you're trying to make, and you're hammering the reality of the markets until you can make the point. I'm confused because I don't think I know your point, so I have to keep pointing out where your claims are wrong. You've just made another one:
"Companies that do well after being taken over by someone else don't count, because as a former shareholder in the taken-over company, you don't get exposure to the success after takeover."
Companies being taken over in stock deals is very common. If they do well afterward, your stock in the company that took them over will rise. That rising did get mixed with whatever else the company was doing, so if it was a massive company swallowing something tiny, then it wouldn't make so much of a difference, but people have frequently been exposed to the results of a takeover unless they chose to sell. If the takeover was at the peak of the bubble, it's likely those results are something you don't want to be involved in, but people still had to actively make that choice. But as I said, calculating that would be hard, so I didn't try to make any claims based on it.
As for private companies not counting, well, duh. That's why I mentioned them as the biggest problem in finding counterexamples; I'd think something like "Netflix was founded around then, and their shipping videos around probably would have made them bubbly", but I'd check and find they only went on the market in 2004, so that doesn't prove anything because they weren't in the bubble, or at least the public part I get numbers for. When I thought of a name and it was in the bubble, the chances were relatively good that it was up from its peak. The seven companies I listed were the result of checking about twelve, with two that didn't make it back and three that weren't on the market. I didn't have to pick and choose to get them, and even if I did, it would still be very different from your "two and only two" inaccurate report.
The fact remains that what you said was wrong with multiple clear counterexamples. You first attempted to downplay this by focusing on one of the seven and a time period of your choosing, even though using the then-to-now time period you originally used works with that one too. You ignored plenty of examples that were even clearer disproofs. And now you're putting effort into explaining how the things I didn't count don't count. At the start of this process, I assumed that you were simply mistaken. Now, it appears that you've got a point to make and are telling the rest of reality to get in line. I don't know where you heard the "only Apple and Amazon" claim before, but sorry, they were wrong. If you keep defending them, you will also be wrong.
