Mutual funds pool money from the investing public and use that money to buy other securities, usually stocks and bonds. The value of the mutual fund company depends on the performance of the securities it decides to buy. So, when you buy a unit or share of a mutual fund, you are buying the performance of its portfolio or, more precisely, a part of the portfolio's value. Investing in a share of a mutual fund is different from investing in shares of stock. Unlike stock, mutual fund shares do not give its holders any voting rights. A share of a mutual fund represents investments in many different stocks (or other securities) instead of just one holding.
That's why the price of a mutual fund share is referred to as the net asset value (NAV) per share, sometimes expressed as NAVPS. A fund's NAV is derived by dividing the total value of the securities in the portfolio by the total amount of shares outstanding. Outstanding shares are those held by all shareholders, institutional investors, and company officers or insiders. Mutual fund shares can typically be purchased or redeemed as needed at the fund's current NAV, which—unlike a stock price—doesn't fluctuate during market hours, but it is settled at the end of each trading day.
The average mutual fund holds hundreds of different securities, which means mutual fund shareholders gain important diversification at a low price. Consider an investor who buys only Google stock before the company has a bad quarter. He stands to lose a great deal of value because all of his dollars are tied to one company. On the other hand, a different investor may buy shares of a mutual fund that happens to own some Google stock. When Google has a bad quarter, she loses significantly less because Google is just a small part of the fund's portfolio.

How Mutual Funds Work


A mutual fund is both an investment and an actual company. This dual nature may seem strange, but it is no different from how a share of AAPL is a representation of Apple Inc. When an investor buys Apple stock, he is buying partial ownership of the company and its assets. Similarly, a mutual fund investor is buying partial ownership of the mutual fund company and its assets. The difference is that Apple is in the business of making innovative devices and tablets, while a mutual fund company is in the business of making investments.
Investors typically earn a return from a mutual fund in three ways:
  1. 1. Income is earned from dividends on stocks and interest on bonds held in the fund's portfolio. A fund pays out nearly all of the income it receives over the year to fund owners in the form of a distribution. Funds often give investors a choice either to receive a check for distributions or to reinvest the earnings and get more shares.

  2. 2. If the fund sells securities that have increased in price, the fund has a capital gain. Most funds also pass on these gains to investors in a distribution.

  3. 3. If fund holdings increase in price but are not sold by the fund manager, the fund's shares increase in price. You can then sell your mutual fund shares for a profit in the market.
If a mutual fund is construed as a virtual company, its CEO is the fund manager, sometimes called its investment adviser. The fund manager is hired by a board of directors and is legally obligated to work in the best interest of mutual fund shareholders. Most fund managers are also owners of the fund. There are very few other employees in a mutual fund company. The investment adviser or fund manager may employ some analysts to help pick investments or perform market research. A fund accountant is kept on staff to calculate the fund's NAV, the daily value of the portfolio that determines if share prices go up or down. Mutual funds need to have a compliance officer or two, and probably an attorney, to keep up with government regulations.
Most mutual funds are part of a much larger investment company; the biggest have hundreds of separate mutual funds. Some of these fund companies are names familiar to the general public, such as Fidelity Investments, The Vanguard Group, T. Rowe Price, and Oppenheimer Funds.

Types of Mutual Funds


Mutual funds are divided into several kinds of categories, representing the kinds of securities they have targeted for their portfolios and the type of returns they seek. There is a fund for nearly every type of investor or investment approach. Other common types of mutual funds include money market funds, sector funds, alternative funds, smart-beta funds, target-date funds, and even funds-of-funds, or mutual funds that buy shares of other mutual funds.

Equity Funds


The largest category is that of equity or stock funds. As the name implies, this sort of fund invests principally in stocks. Within this group are various subcategories. Some equity funds are named for the size of the companies they invest in: small-, mid-, or large-cap. Others are named by their investment approach: aggressive growth, income-oriented, value, and others. Equity funds are also categorized by whether they invest in domestic (U.S.) stocks or foreign equities. There are so many different types of equity funds because there are many different types of equities. 

Index Funds


Another group, which has become extremely popular in the last few years, falls under the moniker "index funds." Their investment strategy is based on the belief that it is very hard, and often expensive, to try to beat the market consistently. So, the index fund manager buys stocks that correspond with a major market index such as the S&P 500 or the Dow Jones Industrial Average (DJIA). This strategy requires less research from analysts and advisors, so there are fewer expenses to eat up returns before they are passed on to shareholders. These funds are often designed with cost-sensitive investors in mind.

Balanced Funds


Balanced funds invest in a hybrid of asset classes, whether stocks, bonds, money market instruments, or alternative investments. The objective is to reduce the risk of exposure across asset classes.This kind of fund is also known as an asset allocation fund. There are two variations of such funds designed to cater to the investors objectives.
Some funds are defined with a specific allocation strategy that is fixed, so the investor can have a predictable exposure to various asset classes. Other funds follow a strategy for dynamic allocation percentages to meet various investor objectives. This may include responding to market conditions, business cycle changes, or the changing phases of the investor's own life.
While the objectives are similar to those of a balanced fund, dynamic allocation funds do not have to hold a specified percentage of any asset class. The portfolio manager is therefore given freedom to switch the ratio of asset classes as needed to maintain the integrity of the fund's stated strategy.

Money Market Funds


The money market consists of safe (risk-free), short-term debt instruments, mostly government Treasury bills. This is a safe place to park your money. You won't get substantial returns, but you won't have to worry about losing your principal. A typical return is a little more than the amount you would earn in a regular checking or savings account and a little less than the average certificate of deposit (CD). While money market funds invest in ultra-safe assets, during the 2008 financial crisis, some money market funds did experience losses after the share price of these funds, typically pegged at $1, fell below that level and broke the buck.

Income Funds


Income funds are named for their purpose: to provide current income on a steady basis. These funds invest primarily in government and high-quality corporate debt, holding these bonds until maturity in order to provide interest streams. While fund holdings may appreciate in value, the primary objective of these funds is to provide steady cash flow​ to investors. As such, the audience for these funds consists of conservative investors and retirees. Because they produce regular income, tax-conscious investors may want to avoid these funds.

International/Global Funds

An international fund (or foreign fund) invests only in assets located outside your home country. Global funds, meanwhile, can invest anywhere around the world, including within your home country. It's tough to classify these funds as either riskier or safer than domestic investments, but they have tended to be more volatile and have unique country and political risks. On the flip side, they can, as part of a well-balanced portfolio, actually reduce risk by increasing diversification, since the returns in foreign countries may be uncorrelated with returns at home. Although the world's economies are becoming more interrelated, it is still likely that another economy somewhere is outperforming the economy of your home country.

Specialty Funds


These types of mutual funds forgo broad diversification to concentrate on a certain segment of the economy or a targeted strategy. Sector funds are targeted strategy funds aimed at specific sectors of the economy, such as financial, technology, health, and so on. Sector funds can, therefore, be extremely volatile since the stocks in a given sector tend to be highly correlated with each other. There is a greater possibility for large gains

Regional funds make it easier to focus on a specific geographic area of the world. This can mean focusing on a broader region (say Latin America) or an individual country (for example, only Brazil). An advantage of these funds is that they make it easier to buy stock in foreign countries, which can otherwise be difficult and expensive. Just like for sector funds, you have to accept the high risk of loss, which occurs if the region goes into a bad recession.

Socially-responsible funds (or ethical funds) invest only in companies that meet the criteria of certain guidelines or beliefs. For example, some socially-responsible funds do not invest in "sin" industries such as tobacco, alcoholic beverages, weapons, or nuclear power. The idea is to get competitive performance while still maintaining a healthy conscience. Other such funds invest primarily in green technology, such as solar and wind power or recycling.


Advantages of Mutual Funds



There are a variety of reasons that mutual funds have been the retail investor's vehicle of choice for decades. The overwhelming majority of money in employer-sponsored retirement plans goes into mutual funds. Multiple mergers have equated to mutual funds over time.

Diversification


Diversification, or the mixing of investments and assets within a portfolio to reduce risk, is one of the advantages of investing in mutual funds.
Buying a mutual fund can achieve diversification cheaper and faster than by buying individual securities. Large mutual funds typically own hundreds of different stocks in many different industries.
It wouldn't be practical for an investor to build this kind of a portfolio with a small amount of money.

Easy Access


Trading on the major stock exchanges, mutual funds can be bought and sold with relative ease, making them highly liquid investments. Also, when it comes to certain types of assets, like foreign equities or exotic commodities, mutual funds are often the most feasible way—in fact, sometimes the only way—for individual investors to participate.
Economies of scale
Buying one spares the investor of the numerous commission charges needed to create a diversified portfolio. Buying only one security at a time leads to large transaction fees, which will eat up a good chunk of the investment. Also, the $100 to $200 an individual investor might be able to afford is usually not enough to buy a round lot of the stock, but it will purchase many mutual fund shares. The smaller denominations of mutual funds allow investors to take advantage of dollar cost averaging.
Because a mutual fund buys and sells large amounts of securities at a time, its transaction costs are lower than what an individual would pay for securities transactions. Moreover, a mutual fund, since it pools money from many smaller investors, can invest in certain assets or take larger positions than a smaller investor

Professional Management


A primary advantage of mutual funds is not having to pick stocks and manage investments. Instead, a professional investment manager takes care of all of this using careful research and skillful trading. Investors purchase funds because they often do not have the time or the expertise to manage their own portfolios, or they don't have access to the same kind of information that a professional fund has. A mutual fund is a relatively inexpensive way for a small investor to get a full-time manager to make and monitor investments. Most private, non-institutional money managers deal only with high-net-worth individuals—people with at least six figures to invest. However, mutual funds, as noted above, require much lower investment minimums. So, these funds provide a low-cost way for individual investors to experience and hopefully benefit from professional money management.

Example of a Mutual Fund


One of the most famous mutual funds in the investment universe is Fidelity Investments' Magellan Fund (FMAGX). Established in 1963, the fund had an investment objective of capital appreciation via investment in common stocks.The fund's glory days were between 1977 and 1990, when Peter Lynch served as its portfolio manager. Under Lynch's tenure, Magellan regularly posted 29% annual returns, almost double that of the S&P 500.
Even after Lynch left, Fidelity's performance continued strong, and assets under management (AUM) grew to nearly $110 billion in 2000, making it the largest fund in the world. By 1997, the fund had become so large that Fidelity closed it to new investors and would not reopen it until 2008.
As of April 2019, Fidelity Magellan has over $16 billion in assets and has been managed by Jeffrey Feingold since 2011, with Sammy Simnegar becoming a co-manager in Feb. 2019.The fund's performance has pretty much tracked or slightly surpassed that of the S&P 500.
