Methodology#

Holdings and weights are sourced from the fund’s portfolio as disclosed to the SEC on Form N-PORT — a public filing. Portfolio filings are quarterly (public ~60 days after quarter end), so we anchor on the latest one and roll each weight forward daily by that holding’s price move, keeping the numbers current between filings; positions in stocks ChartRow doesn’t track carry their filed weight unchanged and show “—” where we have no data. Returns are total returns (dividends reinvested). One row per issuer: a bond fund holds many individual bonds from the same borrower, so we combine them — every U.S. Treasury note and bond becomes one line, as does each corporate issuer — which is how the fund’s own literature presents the portfolio. AGG tracks US Bond Market — for the index itself (returns by year, sector history, valuation), see the US Bond Market research pages. Past performance does not predict future returns; not investment advice.
