How current is AMERICAN CENTURY MUNICIPAL TRUST's holdings data on StockSifting?
Holdings data for AMERICAN CENTURY MUNICIPAL TRUST on StockSifting is sourced from its most recent SEC EDGAR N-PORT filing.
Under SEC rules, registered investment companies must file N-PORT reports monthly, but these are made publicly available approximately 60 days after the reporting period end date. This means the holdings shown on this page reflect the fund's portfolio from roughly two months prior — not today's exact positions.
The Report date displayed at the top of this page indicates exactly when the underlying data was current. If the fund has made significant portfolio changes since that date — responding to market events, earnings releases, or macro shifts — those changes will not be reflected here until the next N-PORT filing is released.
For the most up-to-date holdings before the public disclosure window, refer to the fund's official website or SEC EDGAR directly. StockSifting is best used for fundamental research and historical portfolio analysis, not real-time trading decisions.
