One thing I noticed on 'Invisible Hands' so far is how much the global macro managers focus on the business side of things as opposed to the market side. Volatility, redemptions, cash for liquidity, communicating with clients, etc. And how much those that didnt got hurt in 2008 when liquidity dried up and clients started to redeem.
I dont find that aspect much fun to be honest, right now I trade through a corporation so I can be taking client money, I'm talking with some people to do that but I'm not yet sure I will go down that path. I'm willing to tolerate bigger drawdowns then what the clients would so they would hurt the returns. Some of that can be offset by the fees I suppose but I find really fun is to research and put trades on, not explain why I lost money in the month or have do deal with withdraws.
I suppose a solution is to propose a half-yearly withdraw window, and only take clients who accept this
