To those of you shorting Amazon and AMD, thank you for your money. I will spend it on frivolous and unnecessary things that you can no longer afford, just like a good capitalist.

If you short on the basis of which stock “deserves” to be worth what money, you are forever doomed. This is not how the market works. There is no “deserve.” There is only what is and what is not. Fundamental analysis is not sensible when the market is not rational. Hint: contrary to what you’ve been told, most of the time the market is not rational. Examining the fundamentals except over the very long term will not help you here. Your algorithms also will not help you as they can only use past data. Past data cannot determine the future.

It’s actually easier to make money now that the market is so algorithmic. I worried that the opposite would be true a few years ago, but the algorithms by nature are far dumber than humans, and far easier to predict.
