Data provided bySource: Twelve DataAbout VSIGX#
Objective: “Vanguard Intermediate-Term Treasury Index Fund (the “Fund”) seeks to track the performance of a market-weighted Treasury index with an intermediate-term dollar-weighted average maturity.”
How it invests: “The Fund employs an indexing investment approach designed to track the performance of the Bloomberg U.S. Treasury 3-10 Year Index (the “Target Index”), which includes bonds issued by the U.S. Treasury (not including inflation-protected securities, floating rate securities, and certain other security types), all with maturities between 3 and 10 years. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the bonds that make up the Target Index.”
Same portfolio as VGIT (ETF, 0.04% a year): VSIGX is another share class of the same fund, so what differs between them is the fee and how each is bought.

Annualized returns (CAGR)#
Data provided bySource: Twelve DataCompound annual growth rate per holding period, total return (dividends reinvested), from weekly adjusted closes. Each column is anchored at the date under it; horizons the fund’s history can’t span are omitted.
Fund flows#
Net creations minus redemptions per period, from the fund’s SEC Form N-PORT filings (series-level: where a fund shares its portfolio with mutual-fund share classes, flows cover all classes combined). Quarterly filings publish with a ~60-day lag, so recent months appear as filings land. Flow data begins mid-2019 — Form N-PORT did not exist before then, for any fund.
