Fidelity Short-Term Treasury Bond Index Fund 

This fund typically allocates a minimum of 80% of its assets to the constituent securities of the Bloomberg Barclays U.S. 1-5 Year Treasury Bond Index. It aims to sustain a dollar-weighted average maturity of three years or less, mirroring the benchmark's characteristics. To emulate the index's performance, the advisor employs sophisticated statistical sampling methodologies, evaluating factors such as duration, maturity, interest rate sensitivity, security structure, and credit quality, while utilizing a streamlined selection of holdings rather than holding every security in the index.
