I am sure that some rare managers have a clue, but unlike many scientific, technical, and trade disciplines, in the realm of gambling, it takes time to distinguish talent from imitation. If you load up on a bunch of financial terms of art, you can create a pretty good screen. If you do well for a time, you will likely even convince yourself of your acumen. My wife and I still laugh about a time that we listened to a FM pitch for about an hour until he said "1 million", and we both corrected him at the same time with: "No, you mean 100 thousand". I haven't read the book, but I found the movie entertaining. The celebrity explanations were terrible and unnecessary, however.

Jared Dillian pointed out that the ones that are any good at it have no reason for you to know they exist. They play with their money, make more of it, and have little reason to involve you in the equation in any way shape or form. In fact, considering how much obfuscation is going on, your awareness of their presence and actions substantially hampers their success. The movie was entertaining, to a point. The book was orders of magnitude better.
