I watched "The Big Short" movie yesterday and loved it. It's about the smart and very single-minded traders who predicted the subprime disaster / GFC and bet millions or billions of other peoples money that it would happen. The film is very entertaining and informative. It didn't dumb things down too much but also it wasn't boring to watch. It is a good film to watch to get a good idea about how to spot opportunities. And how difficult it is to even believe something yourself if no one else has the same opinion but no one else has looked at the facts. A bit like believing the earth goes around the sun, err. back in the day when people didn't believe that. The traders are obviously very math smart but what I take away from it is there willingness to do the due diligence and believe in the numbers over emotion (the emotions of every other person in the USA, indeed the world!) netted them a lot of money.
