About FIBUX

Fidelity Flex U.S. Bond Index Fund is an open-end mutual fund that primarily aims to mirror the overall performance of the U.S. investment-grade bond market. By tracking the Bloomberg U.S. Aggregate Bond Index, the fund invests at least 80% of its assets in a diversified pool of U.S. bonds, including government, corporate, and mortgage-backed securities. Employing statistical sampling, the fund manages interest rate sensitivity, credit quality, and sector representation to efficiently replicate the benchmark’s risk-return characteristics with thousands of underlying holdings. Launched in 2017 by Fidelity Investments, it features no minimum investment and is positioned as a passively managed, intermediate core bond fund. The fund’s structure makes it a representative vehicle for broad fixed income market exposure, serving both institutional and individual investors interested in tracking aggregate U.S. bond performance. Its significant asset size, competitive fee structure, and monthly income distribution also highlight its role as a core fixed income component in diversified portfolios seeking stability and income.
