These investment funds try to profit from the performance of a predeterminated market (a country, a region, equities, bonds, etc.) The goal of these funds is to overperform the predeterminated benchmark index of the individual markets.
These funds don't have a predeterminated market, or a target asset allocation. The investment policy of the funds allow the portfolio manager almost complete flexibility in the way assets are allocated -certainly by paying maximal attention to the compliance with the law-, and all promise to deliver returns that beat the prevailing rate of interest.
