If you are looking for income, diversification, and exposure to a specific asset class, bonds can play an important role in your portfolio. In addition to individual bonds and bond mutual funds, bond exchange-traded funds (ETFs) offer another way to obtain the benefits of fixed income.

Which is right for you? Here are a few key things to know about bond ETFs—and some ETFs to consider.

The big bond world

When it comes to individual bonds, you have a lot of choices. It can be a daunting task to choose the right one for your investment plan, given the size and diversity of the $100 trillion bond universe1.

Buying bonds in the past was more complicated as the bond market used to be more opaque and fragmented. Today, with visibility into recent trades, depth of available inventory, and access to most of the available secondary market offerings, you are able to get a better snapshot of a bond’s value and its liquidity than ever before—although bond markets may still see improvements in the future on market structure and transparency.

In addition, bond mutual funds and bond ETFs are often a low-cost way to buy a diversified basket of bonds, even if you have a relatively small amount of money to invest. For a detailed comparison of the features of bonds, bond mutual funds, and bond ETFs, see the table below.

Bonds vs. bond funds vs. bond ETFs
Income potential Growth potential Principal preservation Fees or expense ratios Investment and diversification
Individual bonds Fixed-rate bonds offer periodic payments of fixed amounts. Other types of bonds may vary payments. None if bought at par value and held to maturity without default. Bonds can be purchased and sold in the secondary market prior to maturity at a profit or loss. Principal or par value of the bond returned at maturity, subject to the creditworthiness of the issuer. Secondary market sale can result in a profit or loss and day-to-day values will fluctuate. Brokerage fees may apply. No fee or charge for new-issue bonds, Treasuries, CDs, and munis. If not held to maturity, transaction cost (bid/ask) will be impacted by position size. The minimum is generally $1,000 to $5,000, depending on the type of bond. To be diversified, you may need to buy a basket of bonds.
Bond mutual funds Regular fund distributions, though amounts vary depending on the underlying bond holdings of the fund. Potential for capital appreciation and loss. Most bond funds do not have a maturity date, so principal will fluctuate. Most funds can be bought and sold daily. Mutual funds charge a fee represented by the expense ratio, which reflects operating expenses as a percentage of the fund’s average net asset, as well as any transaction or load fees. Most funds have a $2,500 to $10,000 minimum investment. Bond funds are portfolios of bonds, which can offer broad diversification, depending on the fund’s investment objective.
Bond ETFs Regular fund distributions, though amounts vary depending on the underlying holdings of the fund. Potential for capital appreciation and loss. ETFs can be bought and sold intraday on an exchange. Most ETFs do not have a maturity date, so principal will fluctuate. Net expense ratios are comparable to similar mutual funds, and trading fees depend on product and platform. ETFs may trade at a premium or discount to net asset value (NAV), and are subject to a bid/ask spread. No minimum investment required. Bond ETFs are portfolios of bonds, which can offer broad diversification, depending on the fund’s investment objective. Some are narrowly focused.

Bond funds up close

While bond mutual funds have been around longer, bond ETFs are growing in popularity. Since the first U.S.-listed bond ETF was launched in 2002, bond ETFs have quickly accumulated roughly $400 billion in assets—although that is still just a fraction of the $3.3 trillion bond mutual fund market.2

Bond ETFs are similar to bond mutual funds in that both hold a basket of individual bonds and are professionally managed, either passively (the fund attempts to mirror the performance of a bond index or benchmark) or actively (the fund attempts to outperform a bond index or benchmark). To date, most bond ETFs are passively managed.

Both bond mutual funds and bond ETFs can provide exposure to a variety of markets, sectors, maturities, and credit qualities.

Their tax treatment is similar, too. When it comes to individual bonds, you generally pay income taxes on interest received at ordinary income rates, unless the bond is tax exempt, but you don’t pay capital gains taxes unless you sell the bond before maturity at a profit. With a bond ETF or fund, you will likely pay both income taxes on interest paid, typically through a monthly dividend, and capital gains when they are paid out, typically through an annual dividend. Many passively managed bond ETFs seek to avoid paying capital gains through tax aware portfolio management.

However, there are some differences. Whereas a bond mutual fund’s price is set at the end-of-day market price, a bond ETF is bought or sold at the intraday market price, which may be different than the ETF's net asset value (NAV).3

Bond mutual funds generally provide holdings disclosure monthly and discourage short-term trading of fund shares. In comparison, bond ETFs are required to disclose their holdings daily to support daily exchange trading activity. Depending on distribution models and to control short-term trading, bond mutual funds may be subject to redemption or transaction fees; bond ETFs are not. Instead, bond ETFs are subject to bid-ask spreads and brokerage commissions or fees.

“Bond ETFs might be most appropriate for those fixed income investors who like the advantages of ETFs, including intraday trading and holdings transparency,” explains Lee Sterne, ETF strategist with Fidelity. “Bond ETFs let you tactically pick and choose when you want to enter and exit the market, based on prevailing market conditions.”

Bond ETF risks

Of course, just as bond ETFs provide certain advantages, they also have risks. Bond ETFs have risks similar to individual bonds and bond mutual funds, such as maturity, interest rate, and credit risk. Bond ETFs also have tracking risk, and their potential valuation may be at a premium or discount to NAV.

Additionally, since bond ETFs are a relatively new product, some may not have a long-enough track record to analyze how they might react to different market conditions and phases of the business cycle.

Abundance of bond ETF opportunities

You should decide for yourself whether bond ETFs, bond mutual funds, or individual bonds are right for you. Or a combination of these different types of products might be suitable, depending on your specific investing objectives, risk constraints, and time horizon. Whatever route you choose, a strong case for active bond management can be made in today’s market, given the size and complexity of the bond universe.

In general, the bond market is volatile, and fixed income securities carry interest rate risk. (As interest rates rise, bond prices usually fall, and vice versa. This effect is usually more pronounced for longer-term securities). Fixed income securities also carry inflation risk, liquidity risk, call risk and credit and default risks for both issuers and counterparties. Lower-quality fixed income securities involve greater risk of default or price changes due to potential changes in the credit quality of the issuer. Foreign investments involve greater risks than U.S. investments, and can decline significantly in response to adverse issuer, political, regulatory, market, and economic risks. Any fixed-income security sold or redeemed prior to maturity may be subject to loss.

Before investing in any mutual fund or exchange-traded fund, you should consider its investment objectives, risks, charges, and expenses. Contact Fidelity for a prospectus, offering circular or, if available, a summary prospectus containing this information. Read it carefully.
Past performance is no guarantee of future results.
Neither diversification nor asset allocation ensures a profit or guarantees against loss.
Any fixed income security sold or redeemed prior to maturity may be subject to a substantial gain or loss. Increases in real interest rates can cause the price of inflation-protected debt securities to decrease.
Interest income generated by Treasury bonds and certain securities issued by U.S. territories, possessions, agencies, or instrumentalities is generally exempt from state income tax but is generally subject to federal income and alternative minimum taxes and may be subject to state alternative minimum taxes.
