A mutual fund is a type of financial vehicle made up of a pool of money collected from many investors to invest in securities like stocks, bonds, money market instruments, and other assets. Mutual funds are operated by professional money managers, who allocate the fund’s assets and attempt to produce capital gains or income for the fund’s investors. A mutual fund’s portfolio is structured and maintained to match the investment objectives stated in its prospectus.

Mutual funds give small or individual investors access to professionally managed portfolios of equities, bonds, and other securities. Each shareholder, therefore, participates proportionally in the gains or losses of the fund. Mutual funds invest in a vast number of securities, and performance is usually tracked as the change in the total market cap of the fund—derived by the aggregating performance of the underlying investments.

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. Ergo, the price of a mutual fund is also updated when the NAVPS is settled.

The average mutual fund holds over a hundred 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.

Investors typically earn a return from a mutual fund in three ways:

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. 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. 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.

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. Experts advocate diversification as a way of enhancing a portfolio’s returns, while reducing its risk. Buying individual company stocks and offsetting them with industrial sector stocks, for example, offers some diversification. However, a truly diversified portfolio has securities with different capitalizations and industries and bonds with varying maturities and issuers. 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

Mutual funds also provide 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.

Disadvantages of Mutual Funds

Liquidity, diversification, and professional management all make mutual funds attractive options for younger, novice, and other individual investors who don’t want to actively manage their money. However, no asset is perfect, and mutual funds have drawbacks too.

Fluctuating Returns

Like many other investments without a guaranteed return, there is always the possibility that the value of your mutual fund will depreciate. Equity mutual funds experience price fluctuations, along with the stocks that make up the fund. The Federal Deposit Insurance Corporation (FDIC) does not back up mutual fund investments, and there is no guarantee of performance with any fund. Of course, almost every investment carries risk. It is especially important for investors in money market funds to know that, unlike their bank counterparts, these will not be insured by the FDIC.

Cash Drag

Mutual funds pool money from thousands of investors, so every day people are putting money into the fund as well as withdrawing it. To maintain the capacity to accommodate withdrawals, funds typically have to keep a large portion of their portfolios in cash. Having ample cash is excellent for liquidity, but money that is sitting around as cash and not working for you is not very advantageous. Mutual funds require a significant amount of their portfolios to be held in cash in order to satisfy share redemptions each day. To maintain liquidity and the capacity to accommodate withdrawals, funds typically have to keep a larger portion of their portfolio as cash than a typical investor might. Because cash earns no return, it is often referred to as a “cash drag.”

High Costs

Mutual funds provide investors with professional management, but it comes at a cost—those expense ratios mentioned earlier. These fees reduce the fund’s overall payout, and they’re assessed to mutual fund investors regardless of the performance of the fund. As you can imagine, in years when the fund doesn’t make money, these fees only magnify losses. Creating, distributing, and running a mutual fund is an expensive undertaking. Everything from the portfolio manager’s salary to the investors’ quarterly statements cost money. Those expenses are passed on to the investors. Since fees vary widely from fund to fund, failing to pay attention to the fees can have negative long-term consequences. Actively managed funds incur transaction costs that accumulate over each year. Remember, every dollar spent on fees is a dollar that is not invested to grow over time.
