Tesla
As an example of how disjointed markets are from reality, look at the latest very public announcement that musk is buying 1B of tesla. he probably owns around 100B. It pushed up the price over 10% after the announcement. So for a 1B "investment", musk gets a 10B immediate return. And what wouldn't surprise me at all is if musk already had a plan in place (because he is an insider) to sell a big chunk of shares in the near future to recoup more than the 1B he "spent". Meanwhile, tesla sales are in the tank, and the prognosis for sales isn't good either. But why care, musk bought another B worth of stock, it must go up.
Me I'm one of those boring investors. I know everyone has to sit down when the music stops on those pie in the sky corps. I buy into companies with profits, dividends and low P/E's. Oddly I don't gamble when I'm in Vegas for a convention either. I think I see a pattern.
