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 company, not per ticker: when a fund holds more than one share class of the same company (Alphabet's GOOGL and GOOG, for example), we combine them into a single row whose weight is the sum of its classes. Past performance does not predict future returns; not investment advice.
