An exchange-traded fund (ETF) is a type of security that tracks an index, sector, commodity, or another asset, but which can be purchased or sold on a stock exchange the same way a regular stock can. An ETF can be structured to track anything from the price of an individual commodity to a large and diverse collection of securities. ETFs can even be structured to track specific investment strategies.
A well-known example is the SPDR S&P 500 ETF (SPY), which tracks the S&P 500 Index. ETFs can contain many types of investments, including stocks, commodities, bonds, or a mixture of investment types. An exchange-traded fund is marketable security, meaning it has an associated price that allows it to be easily bought and sold.
An ETF is a type of fund that holds multiple underlying assets, rather than only one like a stock does. Because there are multiple assets within an ETF, they can be a popular choice for diversification.
An ETF can own hundreds or thousands of stocks across various industries, or it could be isolated to one particular industry or sector. Some funds focus on only U.S. offerings, while others have a global outlook. For example, banking-focused ETFs would contain stocks of various banks across the industry.
Inverse ETFs attempt to earn gains from stock declines by shorting stocks. Shorting is selling a stock, expecting a decline in value, and repurchasing it at a lower price. An inverse ETF uses derivatives to short a stock. Essentially, they are bets that the market will decline. When the market declines, an inverse ETF increases by a proportionate amount. Investors should be aware that many inverse ETFs are exchange-traded notes (ETNs) and not true ETFs. An ETN is a bond but trades like a stock and is backed by an issuer like a bank. Be sure to check with your broker to determine if an ETN is a good fit for your portfolio.
In the U.S., most ETFs are set up as open-ended funds and are subject to the Investment Company Act of 1940 except where subsequent rules have modified their regulatory requirements. Open-end funds do not limit the number of investors involved in the product.
ETFs provide lower average costs because it would be expensive for an investor to buy all the stocks held in an ETF portfolio individually. Investors only need to execute one transaction to buy and one transaction to sell, which leads to fewer broker commissions because there are only a few trades being done by investors. Brokers typically charge a commission for each trade. Some brokers even offer no-commission trading on certain low-cost ETFs reducing costs for investors even further.
An ETF's expense ratio is the cost to operate and manage the fund. ETFs typically have low expenses because they track an index. For example, if an ETF tracks the S&P 500 Index, it might contain all 500 stocks from the S&P, making it a passively managed fund that is less time-intensive. However, not all ETFs track an index in a passive manner.
Exchange Traded Funds | Mutual Funds | Stocks |
ETFs are a type of index funds that track a basket of securities. | Mutual funds are pooled investments into bonds, securities, and other instruments that provide returns. | Stocks are securities that provide returns based on performance. |
ETF prices can trade at a premium or at a loss to the net asset value of the fund. | Mutual fund prices trade at the net asset value of the overall fund. | Stock returns are based on their actual performance in the markets. |
ETFs are traded in the markets during regular hours just like stocks are. | Mutual funds can be redeemed only at the end of a trading day. | Stocks are traded during regular market hours. |
Some ETFs can be purchased commission-free and are cheaper than mutual funds because they do not charge marketing fees. | Some mutual funds do not charge load fees, but most are more expensive than ETFs because they charge administration and marketing fees. | Stocks can be purchased commission-free on some platforms and generally do not have charges associated with them after purchase. |
ETFs do not involve actual ownership of securities. | Mutual funds own the securities in their basket. | Stocks involve physical ownership of the security. |
ETFs diversify risk by tracking different companies in a sector or industry in a single fund. | Mutual funds diversify risk by creating a portfolio that spans multiple asset classes and security instruments. | Risk is concentrated in a stock's performance. |
ETF trading occurs in-kind, meaning they cannot be redeemed for cash. | Mutual fund shares can be redeemed for money at the fund's net asset value for that day. | Stocks are bought and sold using cash. |
Because ETF share exchanges are treated as in-kind distributions, ETFs are the most tax-efficient amongst all three types of financial instruments. | Mutual funds offer tax benefits when they return capital or include certain types of tax-exempt bonds in their portfolio. | Stocks are taxed at ordinary income tax rates or at capital gains rates. |
