Fidelity U.S. Bond Index Fund FXNAX NASDAQ

Fidelity U.S. Bond Index Fund (FXNAX) is a passively managed mutual fund that allocates at least 80% of its assets to bonds included in the Bloomberg U.S. Aggregate Bond Index. The fund employs statistical sampling techniques to replicate index returns by selecting a representative subset of securities based on key factors such as duration, maturity, interest rate sensitivity, security structure, and credit quality. This approach allows the fund to achieve broad market exposure while maintaining operational efficiency through a reduced number of holdings. The fund utilizes Fidelity's central fund structure to deliver diversified fixed income exposure to individual investors seeking index-tracking bond investments.
