Both percentages are the stock’s move, not Dyaarl Lee Anderson Jr.’s return: a disclosure gives a band, never an amount, so nobody can say how much was bought or what it made. They run to the last close we hold — 11 Sep 2026, except where a name has since delisted, when the row names its own last session. We publish no close, no volume and no dollar figure behind them. 9 of the 9 rows shown carry a percentage; the rest are dashes with the reason on the row.

Positions come from the unitedstates/congress-legislators roster, the Office of Government Ethics and the SEC’s Form 4 index. Every disclosed line names its own source and links the document the government published; we print what the filing says and never a price we did not read from it. Headlines and links come from the GDELT Global Knowledge Graph — the story stays with the publisher. The portrait, where we have one, is the public-domain Congressional Bioguide photograph.

Some filings reach us as photographs of paper rather than as a form we can read as text. Those are shown here only once they have been read and checked, so this page can hold fewer lines than the filings behind it contain. The link on every row opens the original document, which is always the full record.
