Reference excerpt

A mutual fund is an investment fund that pools money from many investors to purchase securities. The term is typically used in the United States, Canada, and India. In Europe, UCITS funds, primarily registered in Luxembourg and Ireland, are considered mutual funds, while similar structures include the SICAV and the open-ended investment company (OEIC) in the UK. While exchange-traded funds are generally more popular with investors due to their tradability, lower fees, and tax advantages, mutual funds are popular in the U.S. among sponsors of 401(k) plans since open-end funds are priced only at the end of the trading day and fractional shares are easily purchased, making it easy for direct investment from payroll. Mutual funds are often classified by their principal investments: stock fund, bond fund, money market fund, or hybrid fund. Funds may also be categorized as index funds, which are passively managed funds that track the performance of an index, such as a stock market index or bond market index, or actively managed funds, which seek to outperform stock market indices but generally charge higher fees. The types of securities that a particular fund may invest in are set forth in the fund's prospectus, a legal document that describes the fund's investment objective, investment approach and permitted investments. The investment objective describes the type of income that the fund seeks. The primary structures of mutual funds are open-end funds, whereby shares are purchased and sold directly from the issuers at the net asset value, and less commonly, closed-end funds, which are sold on securities exchanges and for which no more shares can be created. Mutual funds have advantages and disadvantages compared to direct investing in individual securities. The advantages of mutual funds include economies of scale, diversification, market liquidity, and professional investment management. A mutual fund is technically a mutual organization. It is organized by a management company, which does not own the fund but receives a management fee. Mutual funds are regulated by governmental bodies and are subject to securities laws. Fund managers are required to publish information including performance, comparisons of performance to benchmarks, fees charged, and securities held. A single mutual fund may have several share classes, for which larger investors pay lower fees.

Market size At the end of 2023, open-end mutual fund assets worldwide were $69.0 trillion. The countries with the largest mutual fund industries are:

United States: $38.8 trillion Luxembourg: $5.8 trillion Ireland: $4.5 trillion China: $3.4 trillion Germany: $2.7 trillion Australia: $2.6 trillion France: $2.5 trillion Japan: $2.2 trillion United Kingdom: $2.0 trillion Canada: $1.8 trillion In the United States, at the end of 2024, 24% of household financial assets were invested in mutual funds. Almost half of U.S. mutual funds assets were held in individual retirement accounts, 401(k) plans, or other defined contribution retirement plans. Mutual funds accounted for 38% of the assets in individual retirement accounts and 60% of the assets in 401(k) plans.

History

Early history The first modern investment funds, the precursor of mutual funds, were established in the Dutch Republic. In response to the financial crisis of 1772–1773, Amsterdam-based businessman Abraham (or Adriaan) van Ketwich formed a trust named Eendragt Maakt Magt ("unity creates strength"). His aim was to provide small investors with an opportunity to diversify. The first investment trust in the UK, the Scottish American Investment Trust formed in 1873, is considered the "most obvious progenitor" to the mutual fund, according to Diana B. Henriques. One of the earliest investment companies in the U.S. similar to a modern mutual fund was the Boston Personal Property Trust that was founded in 1893; however, its original intent was as a workaround to Massachusetts law restricting corporate real estate holdings rather than investing. Early U.S. funds were generally closed-end funds with a fixed number of shares that often traded at prices above the portfolio net asset value. The first open-end mutual fund with redeemable shares was established on March 21, 1924, as the Massachusetts Investors Trust, which is still in existence today and managed by MFS Investment Management. In the U.S., there were nearly six times as many closed-end funds as mutual funds in 1929. After the Wall Street Crash of 1929, the United States Congress passed a series of acts regulating the securities markets in general and mutual funds in particular.

Worked examples

Example 1 — a first encounter with Mutual fund

Start with the simplest possible case. Write down what Mutual fund claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mutual fund before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mutual fund ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mutual fund

In research: Mutual fund appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mutual fund in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mutual fund is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dutch inventions, Institutional investors, Mutual funds, so understanding it makes those chapters shorter.
In everyday life: Look for Mutual fund outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
