Quote from sle:
This might be true for retail pikers (also known as "profitable independent traders" on this forum), but in real life any large risk-taking enterprise is a multifaceted venue with a long of people pooling different strategies and different skills. The real objection to my points is that usually the diversification effect can be easily achieved at the general partner level (assuming a hedge fund) without any serious collaboration between the traders themselves.
This said, pretty much every successful hedge fund starts up the way I described it, as a multi-skill partnership between a few smart guys (usually later becoming a multi-billion dollar AUM-hogging monstrosity). That is true even for most funds with a single "headline" partner, there is usually a few guys that you just don't hear about as much. FoF and the seeders usually really like to hear that there is a diverse set of skills and strategies being pooled together.
I think the key problem is that such a partnership would work if you have either worked together of known each other for a while because it requires more trust then any other business model. E.g. if I partner up with someone, he'll know all about my volatility trading "secrets" and I'd know about his, thus diluting the value of the intellectual property. I definitely can't imagine it working at a prop firm where everyone is coming and going all the time.
