Fund managers are professionals who manage investment funds on behalf of their clients. They make decisions about buying and selling securities, such as stocks or bonds, with the goal of generating returns for the fund's investors while minimizing risk. Fund managers typically have specialized knowledge in a particular area, such as equity or fixed income, and they use this expertise to make informed decisions about which assets to purchase for their funds. They may also employ analysts and other researchers to help them identify promising investment opportunities. In exchange for their services, fund managers typically charge a fee based on the amount of money under management or as a percentage of the fund's performance.
