MRK congressional trades — FAQ

Who in Congress traded MRK?

House Clerk periodic reports for 2025 and 2026 contain 41 verified MRK rows from 16 members: Bruce Westerman, Byron Donalds, C. Franklin, Gilbert Cisneros, and 12 other members. Image-only filings are excluded, and this is not a live brokerage statement.

Does this page show current MRK holdings?

No. STOCK Act filings disclose reportable transactions after the fact, usually within 45 days, as amount ranges and owners. They do not prove a current position, an exact share count, or why the trade happened.

Why are MRK amounts shown as ranges?

House periodic transaction reports use statutory value bands such as $15,001 - $50,000; $1,001 - $15,000. Yield Theory keeps those ranges instead of inventing a midpoint, exact trade size, or return.

How complete is MRK congressional-trade coverage?

This snapshot covers every machine-readable House periodic transaction report for 2025 and 2026 (142 members). Image-only filings and Senate eFD filings are not included, so missing rows are not proof that no other lawmaker traded MRK.

Yield Theory is not affiliated with any elected official. This page uses the 2025–2026 House Clerk periodic report snapshot generated 2026-09-20. It is not a complete lifetime portfolio, a performance track record, or investment advice.

A disclosure is not a thesis.

This page shows who reported MRK and in what range. Membership is the monthly sourced call, plus a five-minute check when the evidence moves. $15/month or $150/year.
