Here’s companies you don’t short: companies that are going up like a Falcon 9 Heavy!
This is a terrible strategy almost always. If you really think you need to short something, an option contract is almost (99% of the time) a better alternative. You limit your losses in a predictable fashion and the gains can be nearly as much — often more.
Ya’ll motherfuckers don’t understand risk — and that goes for the people who write the algorithms.
Companies you short (which I never really recommend) are for example RIM after the iPhone is released, etc.
“Masters of the universe” my ass. Dumber than dirt is more like it.
