What are mutual funds?
A mutual fund is a company that pools money from many investors and invests the money in securities such as stocks, bonds, and short-term debt. The combined holdings of the mutual fund are known as its portfolio. Investors buy shares in mutual funds. Each share represents an investor’s part ownership in the fund and the income it generates.organized with the condition.
As with any business, running a mutual fund involves costs. Funds pass along these costs to investors by charging fees and expenses. Fees and expenses vary from fund to fund. A fund with high costs must perform better than a low-cost fund to generate the same returns for you.

Even small differences in fees can mean large differences in returns over time. For example, if you invested $10,000 in a fund with a 10% annual return, and annual operating expenses of 1.5%, after 20 years you would have roughly $49,725. If you invested in a fund with the same performance and expenses of 0.5%, after 20 years you would end up with $60,858.

It takes only minutes to use a mutual fund cost calculator to compute how the costs of different mutual funds add up over time and eat into your returns. See the Mutual Fund Glossary for types of fees.

Avoiding fraud
By law, each mutual fund is required to file a prospectus and regular shareholder reports with the SEC. Before you invest, be sure to read the prospectus and the required shareholder reports. Additionally, the investment portfolios of mutual funds are managed by separate entities know as “investment advisers” that are registered with the SEC. Always check that the investment adviser is registered before investing.
