Performance Comparison
Comparing historical returns is a crucial factor when assessing the performance of AGG and BND. Over the past decade, AGG has slightly outperformed BND, delivering average annual returns of 4.12% versus 3.90% for BND.
Yields are another important metric to consider when comparing AGG and BND’s performance.
As of September 2021, AGG had a yield of 1.14%, while BND had a yield of 1.51%. AGG tends to generate lower yields due to its focus on high-quality, low-risk bonds. BND may provide slightly higher yields due to its inclusion of corporate bonds.
Investors should also consider volatility when assessing the performance of AGG and BND. AGG has exhibited lower volatility compared to BND, providing more stable returns for risk-averse investors.
AGG has a 3-year standard deviation of 2.71%, compared to BND’s 3-year standard deviation of 2.87%.

While fund flows do not necessarily indicate future performance, they can reflect investor sentiment towards each ETF.
It is important to note that past performance is not a guarantee of future results and that investors should conduct thorough research and seek professional advice before making any investment decisions.
Diversification and Risk Management
Diversification is a key element of managing risk in a portfolio. AGG and BND offer investors exposure to a range of bond types, which can help mitigate specific risk exposure.
AGG’s diversification provides stability, primarily due to its allocation to U.S. government bonds. BND, with its inclusion of corporate bonds, presents a greater potential for higher returns but also involves higher credit risk.
Investors should consider their risk tolerance when selecting between AGG and BND. AGG, with its focus on high-quality bonds, may be appropriate for more risk-averse individuals or conservative portfolios.
BND, with its higher credit exposure, may appeal to investors seeking slightly higher returns and those comfortable with moderate risk. (Note, however, that AGG has outperformed BND over the last decade, as stated above.)
Tax Efficiency and Cost-Effectiveness
AGG has historically been more tax-efficient than BND due to its exposure to tax-exempt municipal bonds. Municipal bonds are generally tax-free at the federal level and, in some cases, at the state and local levels.
Both AGG and BND have relatively low expense ratios compared to other bond ETFs. AGG’s expense ratio is 0.04%, while BND’s expense ratio is 0.035%. However, expense ratios are subject to change, and investors should monitor these costs regularly.
Investors should also consider trading costs when comparing AGG and BND. Trading costs are incurred when buying or selling an ETF, and they can reduce an investor’s returns over time. AGG may have lower trading costs than BND due to its somewhat higher liquidity.
Yield is another important metric to consider when evaluating tax efficiency and cost-effectiveness.
While AGG tends to generate lower yields due to its focus on high-quality bonds, BND may provide slightly higher yields due to its inclusion of corporate bonds. Again, AGG has outperformed BND over the past decade, so these facts are not always predictive.
Investor Considerations
Investors should consider their risk tolerance when choosing between AGG and BND.
AGG may be more appropriate for individuals with a lower risk tolerance due to its focus on high-quality government bonds, while BND may be more appropriate for individuals seeking slightly higher returns and comfortable with moderate risk.
Investors should also consider their investment objectives when choosing between AGG and BND.
AGG may be suitable for income-oriented investors seeking stability, while BND may appeal to investors seeking a balance between risk and potential returns.
Diversification is crucial in managing risk in a portfolio. AGG and BND offer investors exposure to a range of bond types, which can help mitigate specific risk exposure.
Investors should review the underlying holdings of each ETF regularly to ensure they align with their investment objectives.
Monitoring market trends and factors influencing the bond market is essential for investors considering AGG and BND.
Changes in interest rates, inflation, and other macroeconomic factors can impact the performance of both ETFs, and investors should stay informed to make informed investment decisions.

A financial advisor can provide guidance on portfolio construction, risk management, tax considerations, and other relevant factors when choosing between AGG and BND.
