Three dates to check before calling a valuation fresh

Distinguish filing dates, valuation-event dates and audit checks, and understand what the source calendar does—and does not—publish.

The holdings baseline date

This is the date attached to the configured portfolio or filing dataset. The disclosed weights and holding fair values refer to that baseline. A newer company announcement does not automatically update the fund’s ownership, cash balance or share count. The look-through tool keeps baseline dates next to weights so readers can see when a comparison combines different reporting periods.

The valuation event date

This belongs to the financing, transaction or other source record used by the model. It is the date relevant to valuation age. A company announcement from February remains a February announcement when checked in November. Our source calendar groups records by their supplied event or publisher date, not by the time a collector downloaded the page. Records without a reliable date are not assigned today’s date simply to populate the calendar.

The review or retrieval time

A check time records when evidence was reviewed or retrieved. It is operational context, not proof of a new valuation. The source view distinguishes the audit check from the underlying event. A source can be checked today and still be old, inaccessible or unusable for the model. The page-update timestamp likewise describes the page, not a new fund filing.

Read calendar labels literally

Publisher announcements, historical valuation records and excluded model inputs are distinct categories. The calendar links to source documents; it is not a promise that every headline changed estimated NAV. Proposed transactions, combined-entity values and mismatched subjects may be relevant to research while remaining excluded from the calculation. Our short context notes explain the relationship to a recorded fund exposure without inventing an article’s missing facts.

A practical reading order

Start with the fund’s reporting date, follow the issuer link in the look-through view, and compare the valuation event with its source. Then inspect any exclusions on the source page. If the dataset lacks a primary document or position weight, keep that limitation in the conclusion. A richer page should make those gaps easier to see rather than hide them behind a recent publication date.
