The problem is that the future is uncertain, and price is guided by feelings and impressions. People think Tesla is a great company for a variety of reasons that have nothing to do with math. They trust Elon Musk, they think Tesla has a technological advantage, etc. Of course a lot of people also look at balance sheets and hard facts before making a purchase. The price of Tesla's stock is composed of the coordinated actions of all these people. It turns out that adhering to your narrow idea of value does not help you accurately predict the price of a stock, or even the market as a whole for that matter.
