While there are certainly exceptions, as a general rule a "short" is quite a bit smarter than the average "bull". You have to have your shit together to know what the bulls know, and then know what they don't know as well. On top of that, you have to have your shit together to make money in a realm where the big players keep changing the rules on you when you are proven correct. These guys have to play against nothing less than cheaters and and unlimited army of ignorant investors who buy whatever Jim Cramer tells them to buy, and yet still make money at it.
It is the bulls who are "stuck" in the past, as they refuse to learn the present until it comes up and kicks them in the face.
