Suppose I’m the manager of a giant hedge fund. Suppose I’m soliciting you to come into my fund with a few billion of your $100 billion net worth.
Suppose we’re good friends.
You want to come in because you trust me and you know I know how to make money.
However, you’ll only come in if I tell you how the secret trade I’m working really works.
Okay, I’ll tell you. But you can’t tell a soul. Not because what I’m doing is illegal, but because only a few other guys are doing this, and we all know each other, and we’re kind of all in this together – wink, wink – and we don’t want anyone else in our game.
