For decades, the mutual fund has been the main way ordinary people invest in stocks and bonds. Tens of millions of households hold them, mostly through retirement accounts. A mutual fund lets a person with a few hundred dollars own a professionally managed portfolio that would be impossible to build alone.
How a Mutual Fund Works
A mutual fund pools money from many investors and uses it to buy a collection of securities. Each investor owns shares of the fund, and each share represents a small slice of everything the fund holds. The price of a share is called the net asset value, or NAV. It is calculated once a day, after markets close, by adding up the value of the fund’s holdings and dividing by the number of shares. All purchases and sales that day happen at that price. Investors make money when the holdings rise in value and when the fund passes along dividends and interest.
Types of Funds
Stock funds invest in shares of companies and may focus on a size, such as large or small firms, a style, such as growth or value, or a region. Bond funds hold government or corporate debt and aim for income. Money market funds hold very short-term, low-risk debt and are used as a place to keep cash. Balanced funds mix stocks and bonds. A popular version is the target-date fund, which is built around a retirement year and gradually shifts from stocks toward bonds as that year approaches.
Active and Passive Management
In an actively managed fund, a manager and a team of analysts choose investments in an effort to beat a benchmark. In a passive fund, the portfolio simply copies an index. Active management costs more, because research and trading are expensive. Those costs are a high hurdle. Over long periods, most active funds have delivered lower returns than the indexes they are measured against, which has driven a steady shift of money toward passive funds.
Fees to Watch
The most important cost is the expense ratio, an annual percentage deducted from the fund’s assets. An investor never receives a bill for it, which makes it easy to overlook. Some funds also charge a sales commission called a load, either when shares are bought or when they are sold. Taxes are another cost. When a fund sells holdings at a profit, it must distribute those gains to shareholders, who may owe tax even if they sold nothing themselves. This is less of a concern inside retirement accounts.
Conclusion
Mutual funds offer diversification, professional management, and convenience in a single purchase. They made investing accessible to the middle class and remain the backbone of workplace retirement plans. The differences between funds matter a great deal. Before investing, it is worth checking what a fund actually holds, how it has performed against its benchmark, and above all what it charges.
