Jim Cramer is a bad trader. He is so consistently bad, that he is actually one of the best traders in the entire world. Inversing his calls is constantly profitable, so always make sure to set alerts for when he tweets out stock picks to inverse, and watch all his Mad Money videos. (You can watch on 3-5X speed, he talks real slow. All you need is the picks.)
Don't let it slip past that what he does SHOULD be criminal. He is a crook, stealing from his biggest supporters and using their liqudity to make profit. But that's the market: The bad guys always win. Don't like it? Leave.
