In the quest for diversification, investors often look outside stock-based ETFs and holdings, to hedge market risk, or take advantage of economic events that might run parallel to the overall market. Fixed income exchange-traded funds (ETFs), whose shares are traded on major stock exchanges, are a special type of mutual fund designed to track the performance of a specific bond market index.

Designed and managed by a financial institution or financial information service, bond ETFs track the performance of the overall bond market or of a specific sector (government, corporate, or mortgage-backed), maturity range or credit quality within the larger market. The wide variety of bond ETFs offers investors the opportunity to achieve broad or targeted bond market exposure. Here are the 10 Best AAA grade fixed income ETF offerings for 2019.

1. iPath US Treasury 5-year Bull ETN (DFVL)

The iPath® US Treasury 5-year Bull ETN is designed to provide investors with exposure to the Barclays 5Y US Treasury Futures Targeted Exposure Index™.  The ETNs are unsecured debt obligations of the issuer, Barclays Bank PLC, and are not, either directly or indirectly, an obligation of or guaranteed by any third party.  Any payment to be made on the ETNs, including any payment at maturity or upon redemption, depends on the ability of Barclays Bank PLC to satisfy its obligations as they come due.  An investment in the ETNs involves significant risks, including possible loss of principal, and may not be suitable for all investors.

The Barclays 5Y US Treasury Futures Targeted Exposure Index™(the “Index”) is designed to decrease in response to an increase in the 5-year Treasury note yields and to increase in response to a decrease in 5-year Treasury note yields. The Index targets a fixed level of sensitivity to changes in the yield of the current “cheapest-to-deliver” note underlying the relevant 5-year Treasury futures contract at a given point in time. The Index seeks to achieve its target sensitivity through the allocation of a weighting to the relevant 5-year Treasury futures contract, as traded on the Chicago Board of Trade, underlying the Index. Owning the ETNs is not the same as owning interests in the futures contracts comprising the Index or a security directly linked to the performance of the Index. The expense ratio for the fund is 0.75%.
