Introduction to BND vs. AGG
Overview of Bond ETFs
In bond ETFs, investors enjoy affordable costs and diversification modes of fixed-income products. These funds are distributed across many bond indices; therefore, one could invest in the entire range of bonds without having to buy them as individual securities. The Vanguard Total Bond Market ETF (BND) and iShares Core U.S. Aggregate Bond ETF (AGG) are the two most popular bond ETFs. Their main purpose is income generation through diversified portfolios of U.S. investment-grade bonds.
Why Compare BND and AGG?
BND and AGG are among the biggest and most popular bond ETFs, usually considered as core holding diversifying portfolios. They are typically the same regarding objectives, but include minor differences in makeup, expense ratios, and performance metrics that may influence decisions for a certain investor. The differences should be understood before going ahead with deciding which option is better to have.
Understanding BND and AGG
What Is BND? (Fund Composition, Holdings, Issuer)
Managed by Vanguard, BND looks to track the Bloomberg U.S. Aggregate Float-Adjusted index. It contains combinations of U.S. Treasury securities, corporates, and mortgage-backed securities. With thousands of underlying holdings, BND offers its holders broad exposure to the U.S. bond market.
What Is AGG? (Fund Composition, Holdings, Issuer)
This is an exchange-traded bond fund managed by the iShares division of BlackRock and is designed to replicate the performance of the Bloomberg U.S. Aggregate Bond Index. Similar to its counterpart, BND, AGG consists of U.S. Treasury bonds, corporate bonds, and mortgage-backed securities. This slight difference in performance can be attributed to a somewhat different weighting methodology used by AGG.
