What Is An ETF?
An exchange-traded fund (ETF) is a collection of securities—such as stocks—that tracks an underlying index. The best-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 a marketable security, meaning it has an associated price that allows it to be easily bought and sold.
An ETF is called an exchange-traded fund since it’s traded on an exchange just like stocks. The price of an ETF’s shares will change throughout the trading day as the shares are bought and sold on the market. This is unlike mutual funds, which are not traded on an exchange, and trade only once per day after the markets close.
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.
Types of ETFs
- Bond ETFs might include government bonds, corporate bonds, and state and local bonds—called municipal bonds.
- Industry ETFs track a particular industry such as technology, banking, or the oil and gas sector.
- Commodity ETFs invest in commodities including crude oil or gold.
- Currency ETFs invest in foreign currencies such as the Euro or Canadian dollar.
- 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.
Advantages and Disadvantages of ETFs
ETFs provide lower average costs since 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 since 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 since 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 and less time-intensive. However, not all ETFs track an index in a passive manner.
