Mutual funds use
professional managers to make the decisions regarding which companies' securities should be bought and sold. The managers of the mutual fund decide how the pooled funds will be invested. Investment opportunities are abundant and complex. Fund managers are expected to know what is available, the risks and gains possible, the cost of acquiring and selling the investments, and the laws and regulations in the industry. The ability of the managers to select profitable investments and to sell those likely to decline in value is a key factor for the mutual fund to earn money for the investors.
