The problem with the stock market is, even if you know with 100% certainty that EM is lying and Tesla is overvalued, you only can cash in that knowledge if the stock price makes contact with reality.

In fact even if every single shareholder in Tesla knows that the price is unsustainable they can still hold out for a greater fool for years. To a large extent you are betting on what the crowd will do, not what the company will do.
