17 Best ETFs for Beginners Looking to Start Investing in 2026

8. iShares Core U.S. Aggregate Bond ETF (AGG) - Alternative Bond Market Exposure

The iShares Core U.S. Aggregate Bond ETF (AGG) provides another excellent option for beginning investors seeking broad exposure to the U.S. investment-grade bond market, tracking the same Bloomberg U.S. Aggregate Float Adjusted Index as BND while offering the research and platform benefits of the BlackRock iShares ecosystem. AGG encompasses the full spectrum of U.S. investment-grade bonds, including Treasury securities, government agency bonds, corporate bonds, and mortgage-backed securities, providing comprehensive fixed-income diversification through a single, efficiently managed fund. With an expense ratio of 0.03%, identical to BND, AGG demonstrates the competitive pricing that has made core bond ETFs accessible to investors of all sizes, while the fund's substantial assets under management and high daily trading volume ensure excellent liquidity for investors who need to buy or sell shares. The fund's average duration and credit quality characteristics closely mirror those of BND, making the choice between these two funds largely a matter of personal preference regarding fund provider, platform integration, or specific portfolio management tools. For beginning investors, AGG offers access to professional bond portfolio management that automatically handles complex tasks such as reinvestment of maturing bonds, credit quality monitoring, and duration management, which would be challenging and expensive for individual investors to manage independently. The broad diversification provided by AGG helps protect against various risks including credit risk, interest rate risk, and inflation risk, while providing steady income that can be particularly valuable during periods of stock market volatility. BlackRock's extensive research capabilities and educational resources can provide additional value for new investors seeking to understand fixed-income investing and its role in long-term portfolio construction.
