Start with the extortion and the purloined FBI data.
That was very late in the game. Even so, there were plenty of rumors. And a lot of stuff came out as a result of Tony's big fight with Whatshisname.
For the most part, what they did was simply research stocks, exchange information, and short stocks that deserved shorting.
Tony's great flaw was that he thought he needed an edge, in the form of Royer. He also thought it was cool to buddy up to an FBI agent who was, in my view, far more corrupt than Tony.
