"Active fund" is a term used to describe a type of mutual fund that is managed by a human portfolio manager. This type of fund is often compared to "passive funds," like index funds, which track a specific index rather than being managed by an individual. However, there are several synonyms that are often used interchangeably with "active fund," including "actively managed fund," "managed fund," and "dynamic fund." These terms all describe funds that are continually monitored and adjusted by a professional manager to aim for higher returns than the market average. While active funds can come with higher fees, they may also offer the potential for greater returns.
