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.
