The obvious counter-example to this is Slack, a "pure-tech" company whose value has halved since IPO, and there's a similar story with Snapchat (though its value has recovered somewhat in the past year).
It's just that the described path to success is close to impossible in any other space except for pure tech companies, preferably with a software-only product, which means that any company not fitting that description, but boasting absurd high valuations justified by assuming the company will go the path described above does most likely mislead investors.
I say this as a slack stock holder who lost money, so I clearly know what I'm talking about ;-)
It would not be uncommon for an inferior product to win a significant market share. Especially when it comes to Enterprise software.
just because some greater fool declared it was worth $40 at some point doesn’t mean it’s now a bargain if it goes down to $20.
