A stock is worth what people will pay for it. That’s it. Sure, there are models you can use to come up with a seemingly reasonable valuation, but that’s just a tool you use to make a wild ass guess.
Exactly. I think gold is worthless because it's just a lump of metal that doesn't do anything useful. But apparently there's enough people that like shiny metal and therefore it's worth a lot. GME might just be an aesthetic purchase more than anything.
