This isn't proof for sure, but anyone who has met a car salesman and a Wall Street professional can see that Rufus acts like the former and not the latter. Rich people care about money, and they don't throw around millions, billions, and trillions as if they were chump change. The game is about making money, not vendettas. That's stuff for the World Wrestling Federation.
If you were rich would you give Rufus billions of dollars? Obviously the market's answer is no. When they see him they want to short every share they can find.
