What Is a Mutual Fund?

A mutual fund is a financial product in which money pooled from many investors is invested collectively by a professional asset management company in stocks, bonds, and other assets, with the investment results distributed back to investors.

How it works

Funds contributed by investors are held separately by a trust bank and invested in stocks, bonds, and other assets according to the instructions of the asset management company. A key feature is the ability to diversify across multiple assets with a small amount of money, and the fund's investment policy is set out in advance in its prospectus.

What to keep in mind

The movement of the fund's "net asset value," which shows investment performance, and the level of the ongoing "expense ratio," can be checked beforehand in the prospectus and investment reports. Past investment performance does not guarantee future results, and it is possible for the value to fall below the original amount invested.

Frequently Asked Questions

Is the principal invested in a mutual fund guaranteed?
No. A mutual fund is a financial product that invests in stocks, bonds, and similar assets, and unlike a bank deposit, it has no principal guarantee. Its net asset value moves up and down with the market, and it is possible to lose money relative to the purchase price.
What costs are involved in a mutual fund?
Costs can include a purchase fee, an ongoing expense ratio (management fee) charged throughout the holding period, and a redemption fee charged upon sale. Because the fee structure varies by fund, it is important to check the prospectus.
