While everything you say may be true, this shows a fundamental misunderstanding about how the modern stock market functions. How much value a company creates is at best tangential and often completely orthogonal to how much the stock is worth. The stock market has always been a Keynesian beauty contest, but in the past few decades, strongly shaped and morphed by attention economies. A good example of this is DJT, a company which functionally doesn't do much anything, but in the last year has traded at wildly differing prices. P/E, EBITDA, etc, are all useless metrics in trying to explain this phenomenon.
In other words, NVIDIA is in the red not because the company is suddenly doing worse, but because traders think other traders think it will trade down. That is a self fulfilling prophecy, but only so long as there is sufficient attention to drive that. The same works the other way around as well, so long as there is sufficient attention to drive the AI hype train upwards, related stocks will do well as well.
