Exchange traded funds are a type of investment fund that offer the best attributes of two popular assets: They have the diversification benefits of mutual funds while mimicking the ease with which stocks are traded.
What does "ETF" mean?
An exchange traded fund, or ETF, is a basket of investments like stocks or bonds. Exchange traded funds let you invest in lots of securities all at once, and ETFs often have lower fees than other types of funds. ETFs are traded more easily too.
But like any financial product, ETFs aren’t a one-size-fits-all solution. Evaluate them on their own merits, including management costs and commission fees (if any), how easily you can buy or sell them, how they fit into your existing portfolio and their investment quality.
How do ETFs work?
Exchange traded funds work like this: The fund provider owns the underlying assets, designs a fund to track their performance and then sells shares in that fund to investors. Shareholders own a portion of an ETF, but they don’t own the underlying assets in the fund. Even so, investors in an ETF that tracks a stock index may get lump dividend payments, or reinvestments, for the stocks that make up the index. (Related: Learn how to invest in index funds, or compare index funds and ETFs.)
While ETFs are designed to track the value of an underlying asset or index — be it a commodity like gold or a basket of stocks such as the S&P 500 — they trade at market-determined prices that usually differ from that asset. What’s more, because of things like expenses, longer-term returns for an ETF will vary from those of its underlying asset.
Here is the abbreviated version of how ETFs work:
1. An ETF provider considers the universe of assets, including stocks, bonds, commodities or currencies, and creates a basket of them, with a unique ticker.
2. Investors can buy a share of that basket, just like buying shares of a company.
3. Buyers and sellers trade the ETF throughout the day on an exchange, much like a stock.

Investors have flocked to exchange traded funds because of their simplicity, relative cheapness and access to a diversified product. Here are the pros:
While it’s easy to think of diversification in the sense of the broad market verticals — stocks, bonds or a particular commodity, for example — ETFs also let investors diversify across horizontals, like industries. It would take a lot of money and effort to buy all the components of a particular basket, but with the click of a button, an ETF delivers those benefits to your portfolio. Diversification can help safeguard your portfolio against market volatility. If you invested in just one industry, and that industry had a really bad year, it's likely your portfolio would have performed poorly too. By investing across different industries, company sizes, geographies and more, you give your portfolio more balance. Because ETFs are already well-diversified, you don't have to worry about creating it within your portfolio.
Anyone with internet access can search the price activity for a particular ETF on an exchange. In addition, a fund’s holdings are disclosed each day to the public, whereas that happens monthly or quarterly with mutual funds. This transparency allows you to keep a close eye on what you're invested in. Say you really don't want to be invested in oil. You'd be able to spot those additions to your ETF more easily than with a mutual fund.
ETFs have two major tax advantages over mutual funds.
If you invest in a mutual fund, you may have to pay capital gains taxes (or, the profits from the sale of an asset, like a stock) through the lifetime of your investment. This is because mutual funds, particularly those that are actively managed, often trade assets more frequently than ETFs. Most ETFs, on the other hand, only incur capital gains taxes when you go to sell the investment. This means you'll pay less tax on your ETF investment overall.
As mutual fund managers are actively buying and selling investments, and incurring capital gains taxes along the way, the investor may be exposed to both long-term and short-term capital gains tax. If you're invested in an ETF, you get to decide when to sell, making it easier to avoid those higher short-term capital gains tax rates.

Exchange traded funds may work well for some investors, but they aren't perfect. Here are the cons:
ETF costs may not end with the expense ratio. Because ETFs are exchange-traded, they may be subject to commission fees from online brokers. Many brokers have decided to drop their ETF commissions to zero, but not all have.
Potential liquidity issues
As with any security, you’ll be at the whim of the current market prices when it comes time to sell, but ETFs that aren’t traded as frequently can be harder to unload.
Risk the ETF will close
The primary reason this happens is that a fund hasn’t brought in enough assets to cover administrative costs. The biggest inconvenience of a shuttered ETF is that investors must sell sooner than they may have intended — and possibly at a loss. There’s also the annoyance of having to reinvest that money and the potential for an unexpected tax burden.
How much do ETFs cost?
Exchange traded funds can vary significantly when it comes to cost. The median price of the most popular ETFs by trading volume is $59.42. The most expensive ETF in that list tops out at $473.56 and the lowest comes in at $3.43. That range may feel intimidating, but it also means there is an ETF for every budget. It may help to outline how much you're willing to spend on an ETF before you dive in.
When researching ETFs you'll also need to consider the fund's expense ratio, or the fee the fund charges to manage and maintain it. Because most ETFs are passively managed, ETF expense ratios are typically pretty low compared with other types of funds.

ETFs vs. mutual funds vs. stocks
When comparing exchange traded funds with other investments, ETFs stand out in a number of ways. Lower investment costs, better diversification and an increasing number of options are just a few of the benefits of ETFs.
ETFs vs. mutual funds
Generally speaking, ETFs have lower fees than mutual funds — and this is a big part of their appeal.
ETFs also offer better tax-efficiency than mutual funds. There's generally more turnover within a mutual fund (especially those that are actively managed) relative to an ETF, and such buying and selling can result in capital gains. Similarly, when investors go to sell a mutual fund, the manager will need to raise cash by selling securities, which also can accrue capital gains. In either scenario, investors will be on the hook for those taxes.
The two products also have different management structures (typically active for mutual funds, passive for ETFs, though actively managed ETFs do exist).
ETFs vs. stocks
ETFs are made up of stocks, but there is no such thing as an "ETF stock." You can purchase a share of an ETF, but you cannot purchase stock in an ETF. ETFs are made up of individual stocks and other investments.
Like stocks, ETFs can be traded on exchanges and have unique ticker symbols that let you track their price activity. Unlike stocks, which represent just one company, ETFs represent a basket of stocks. Since ETFs include multiple assets, they may provide better diversification than a single stock. That diversification can help reduce your portfolio’s exposure to risk.
ETFs are sometimes focused around certain sectors or themes. For example, SPY is one of the ETFs that tracks the S&P 500, and there are fun ones like HACK for a cyber-security fund and FONE for an ETF focused on smartphones.
Here are a few of the key differences between ETFs, mutual funds and stocks.

How to find the right ETFs for your portfolio
It's important to be aware that while costs generally are lower for ETFs, they also can vary widely from fund to fund, depending on the issuer as well as on complexity and demand. Even ETFs tracking the same index have different costs.
Most ETFs are passively managed investments; they simply track an index. Some investors prefer the hands-on approach of mutual funds, which are run by a professional manager who tries to outperform the market. There are actively managed ETFs that mimic mutual funds, but they come with higher fees. So consider your investing style before buying.
The explosion of this market also has seen some funds come to market that may not stack up on merit — borderline gimmicky funds that take a thin slice of the investing world and may not provide much diversification. Just because an ETF is cheap doesn’t necessarily mean it fits with your broader investment thesis.

Types of ETFs
Exchange traded funds may trade like stocks, but under the hood they more resemble mutual funds and index funds, which can vary greatly in terms of their underlying assets and investment goals. Below are a few common types of ETFs — just note that these categories aren’t mutually exclusive. For example, a stock ETF might also be index-based, and vice versa. These ETFs aren’t categorized by management type (passive or active), but rather by the types of investments held within the ETF.
These comprise stocks and are usually meant for long-term growth. While typically less risky than individual stocks, they carry slightly more risk than some of the others listed here, such as bond ETFs.
Commodities are raw goods that can be bought or sold, such as gold, coffee and crude oil. Commodity ETFs let you bundle these securities into a single investment. With commodity ETFs, it’s especially important to know what’s inside them — do you have ownership in the fund’s physical stockpile of the commodity, or own equity in companies that produce, transport and store these goods? Does the ETF contain futures contracts? Is the commodity considered a “collectible” in the eyes of the IRS? These factors can come with serious tax implications and varying risk levels.

Unlike individual bonds, bond ETFs don’t have a maturity date, so the most common use for them is to generate regular cash payments to the investor. These payments come from the interest generated by the individual bonds within the fund. Bond ETFs can be an excellent, lower-risk complement to stock ETFs.
Foreign stocks are widely recommended for building a diverse portfolio, along with U.S. stocks and bonds. International ETFs are an easy — and typically less risky — way to find these foreign investments. These ETFs may include investments in individual countries or specific country blocs.
The U.S. stock market is divided into 11 sectors, and each is made up of companies that operate within that sector. Sector ETFs provide a way to invest in specific companies within those sectors, such as the health care, financial or industrial sectors. These can be especially useful to investors tracking business cycles, as some sectors tend to perform better during expansion periods, others better during contraction periods. Often, these typically carry higher risk than broad-market ETFs. Sector ETFs can give your portfolio exposure to an industry that intrigues you, such as gold ETFs or marijuana ETFs, with less risk than investing in a single company.
How to invest in ETFs
There are a variety of ways to invest in exchange traded funds, and how you do so largely comes down to preference. For hands-on investors, investing in ETFs is but a few clicks away. These assets are a standard offering among the online brokers, though the number of offerings (and related fees) will vary by broker. On the other end of the spectrum, robo-advisors construct their portfolios out of low-cost ETFs, giving hands-off investors access to these assets. One trend that’s been good for ETF shoppers — many major brokerages dropped their commissions on stock, ETF and options trades to $0.
1. Open a brokerage account
If you're ready to start investing in ETFs on your own, you'll need to have a brokerage account to do so. Brokerage accounts are where your investments live; just because you have one does not mean you're invested in anything. After you open an account you can invest in ETFs from there.
If you need help, you can work with a robo-advisor or a traditional financial advisor.

2. Find the ETFs you want to invest in
This isn't as complicated as it sounds, but there are lots of ETFs on the market, and it can be tricky narrowing it down. You can use online screeners to help you find ETFs with low costs, funds in particular sectors or ETFs that have a socially responsible or environmental focus.

3. Buy the ETF
Using your brokerage's trading function, navigate to the particular ETF you'd like to buy and place the trade. Make sure you double-check your order before you make it official.
4. Hold onto the ETF
How long you hold onto an ETF will depend on your investment strategy, but if you're investing for retirement, it's often a waiting game: The longer you hold it the better. Because of the nature of compound interest, the longer you hang onto an ETF the longer your interest will be accruing interest.
If you have a long investment timeline you'll likely also be able to ride out the highs and lows of the stock market as it trends upward over time.
Do ETFs pay dividends?
Yes, as long as the underlying stocks held within the ETF pay dividends. These companies’ dividends are collected by the ETF issuer and distributed to investors, typically quarterly, based on the number of shares the investor owns in the ETF. However, if none of the underlying companies in the ETF offer dividends, the ETF won’t pay dividends, either. Some ETFs are constructed specifically to maximize dividend income, known aptly as dividend ETFs.

Can you sell an ETF at any time?
Yes. Just like stocks, ETFs can be bought or sold at any time throughout the trading day (9:30 a.m. to 4 p.m. Eastern time), letting investors take advantage of intraday price fluctuations. This differs from mutual funds, which can only be purchased at the end of the trading day, for a price that is calculated after the market closes.
