Public record, not advice. These are periodic transaction reports that members of Congress file under the STOCK Act, collected from the Clerk of the House and the Senate Office of Public Records. Filings dated January 2, 2026 to October 5, 2026, collected October 6, 2026. Trades are due within 45 days, but some are filed months or even years later, so check each trade date. A disclosure says nothing about why a trade was made. It is not a recommendation to buy or sell anything, and MarketCast does not give investment advice.

How to read this

Amounts are ranges. Filers report a bracket such as $1,001 to $15,000, not an exact figure.
Dates lag. Trades are due within 45 days and some are reported much later, so compare the trade date with the filing date.
Accounts vary. Reports can cover a spouse, a dependent child, or an account a financial adviser manages.
Counts are not conviction. Several lots of one stock in a single filing can be one decision, and a partial sale is counted as a sale.

Common questions

Which members of Congress have disclosed trades in Martin Marietta Materials Inc.?

2 members filed 9 disclosed trades in Martin Marietta Materials Inc. (MLM) in the filings collected here. The table lists them with dates and amount ranges.

Why do disclosed trades show a range instead of an exact amount?

The STOCK Act reporting forms use set dollar brackets, so filers choose a range such as $1,001 to $15,000 instead of stating the exact amount.

How current are these disclosures?

Members are supposed to report a trade within 45 days, but some filings arrive months or years late. Each line shows both the trade date and the filing date, and the data window is at the top of the page.

Does a trade by a member of Congress mean I should buy or sell?

No. Disclosures are a public record of what was filed. They do not say why a trade was made, and they arrive after the fact. MarketCast does not give investment advice.
