Those are the NET published numbers to investors. AFTER the brokerage fees and management fees are deducted. How do you think the evil hedge fund managers get rich? working for nothing? In most funds the fees can equal as much as 50% of the gross returns. so take your published return and double them and that is generally what the fund returned gross. Especially if he is working in the Forex (currency) market. if he actually runs the fund or is one of the people that run it, he probably has access to gross returns. You are not going to find this information on the internet. Do you think the banks and fund mangers want people to know they take up to 50% of the gross for themselves in fees? There is also a limit on how much and how big of trades can be made due to liquidity to support the trade. So no one can make enough to take over the universe so you cant take things to ridiculous extremes. Is anyone actually thinking and being logical on here or just going to whatever extreme assumption they can make in order to say it cant be done? Find an investment banker and ask him about the fees they charge. For smaller accounts like is being described here (taking 5k to 5mil for example) it could certainly be done.if he had access to gross returns which if he runs the fund he would obviously have access to. It might be a good idea to actually know what you are talking about before speculating about things you don't really know about. Do you know what fees Soros charged in Quantum? He is worth a few billion (about 25 as last count). Do you think he made that by giving investors all of the return? Private funds can do anything they want on fees. It is all in the subscription agreement and as long as the investor accepts it, then it is fine.
