Mutual funds allow investors to pool their money together into a portfolio that is professionally managed. The key benefits of mutual funds include diversification of risk, professional management, and reduced transaction costs. A mutual fund is made up of a trust that holds the securities in the fund. The trust is managed by a board of trustees and an asset management company. Regulators like SEBI oversee the mutual fund industry in India and work to protect investors. Distribution channels play an important role in helping mutual funds reach retail investors. Agents and brokers are typically compensated through upfront and trail commissions.
