We probably agree that the stock will eventually reflect value. I think we’d quibble about how long that takes. As the saying goes, the market can remain irrational longer than you can remain solvent. In other words, don’t bet on the market always reflecting reality.
The value of a stock is all pure speculation about how much you can sell it for later.
Look at Tesla. They're doing extremely poorly right now and have been for about a year, and if you look at their stock price you wouldn't think that. They're valued more than, like, every other auto manufacturer combined. Looking at that you'd expect them to hold 50% of the market in all markets they're in. But they don't get anywhere close to that.
The stock market is just gambling. You can't see the other person's hand.
