this company is like citadel, which is that their main business is market making and non-directional trades. They dont pick directional investments, as most investors do. rather they are in the middle picking up pennies, except many billions of them. But these returns may be exaggerated or there is information missing...20% a year far exceeds the rate capital is being created by the global economy. At that rate, it would eventually own the world and all markets. I think their actual returns, assuming the fund still trades (its operations are very opaque) are much less...maybe 5-6% year. The bigger a fund gets, the more impact its trades have on markets, which limits its size
