A sales load is a common fee charged for the buying and selling of mutual fund shares through an intermediary. However, there are certain types of mutual funds that do not impose this charge, known as no-load funds. These funds can be advantageous for investors as they do not have to pay an additional fee, allowing them to potentially earn a higher return on their investment. It is important for investors to understand the various fees associated with mutual funds in order to make informed decisions about their investments.
