Data provided bySource: Twelve DataAbout VIMAX#
Objective: “Vanguard Mid-Cap Index Fund (the “Fund”) seeks to track the performance of a benchmark index that measures the investment return of mid-capitalization stocks.”
How it invests: “The Fund employs an indexing investment approach designed to track the performance of the CRSP US Mid Cap Index (the “Target Index”), a broadly diversified index of stocks of mid-size U.S. companies, as determined by the index provider. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the stocks that make up the Target Index. The Fund attempts to replicate the Target Index by investing all, or substantially all, of its assets in the stocks that make up the Target Index, holding each stock in approximately the same proportion as its weighting in the Target Index.”
Same portfolio as VO (ETF, 0.03% a year): VIMAX 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.
