It maintains 80%+ allocation to fixed-income instruments—including U.S. Treasury and corporate securities—adjusting dynamically based on volatility. ## Investment Strategy ABXB is designed to provide investors with exposure to a diversified portfolio of fixed-income securities through a dynamic, quantitative approach. The ETF invests in five bond-rated ETFs, selecting them based on a momentum model. This model aims to identify ETFs that are exhibiting strong performance characteristics within the fixed-income market. The fund maintains at least 80% of its assets in fixed-income instruments, including U.S. Treasury and corporate securities, offering exposure to a broad range of credit qualities and maturities. The fund dynamically adjusts its allocations based on market volatility, seeking to reduce risk during periods of heightened uncertainty. With nearly 100% exposure to the United States, ABXB focuses primarily on the U.S. fixed-income market. This ETF may appeal to investors seeking a quantitatively managed fixed-income solution with the potential for dynamic adjustments based on market conditions. ## Risk Profile ABXB's risk profile is influenced by its investment strategy and asset allocation. As a fund that invests in other ETFs, ABXB is subject to the risks associated with the underlying ETFs, including interest rate risk, credit risk, and market risk. The fund's dynamic allocation strategy, while intended to mitigate risk, may not always be successful in doing so. The expense ratio of 0.63% can create an expense drag on performance, especially in lower-return environments. With nearly 100% of its exposure in the United States, ABXB has minimal geographic diversification, making it vulnerable to economic and political developments within the U.S. fixed-income market. Investors should carefully consider these risks before investing in ABXB. Past performance does not guarantee future results. ## Country Allocation - United States: 99.8% - Other: 0.2% ## Market Context In the current market environment, fixed-income ETFs like ABXB play a crucial role in portfolio diversification and risk management. Given the uncertainty surrounding interest rates and economic growth, investors are increasingly seeking actively managed fixed-income solutions that can adapt to changing market conditions. ABXB's quantitative momentum strategy may appeal to investors looking for a differentiated approach to fixed income investing. However, the ETF faces competition from a wide range of other fixed-income ETFs, including those with lower expense ratios and more established track records. The performance of ABXB will depend on the effectiveness of its momentum model and its ability to navigate the complexities of the fixed-income market. ## Frequently Asked Questions ### What is ABXB and what does it track?
