What DGX filings don’t tell you
A disclosure row records a trade date, an amount bracket, and who owned the asset. It does not say why the trade was made, whether the position is still held, or anything about the business behind the ticker: revenue trends, margins, balance-sheet risk, or valuation. Those answers are in company filings, not congressional ones.

DGX congressional trades: FAQ
Who in Congress traded DGX?
House Clerk and Senate eFD periodic reports for 2025 and 2026 contain 9 verified DGX rows from 4 members: Alan Armstrong, Carol Miller, Julia Letlow, and Julie Johnson. Image-only filings are excluded, and this is not a live brokerage statement.
Does this page show current DGX 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 DGX amounts shown as ranges?
Congressional periodic transaction reports use statutory value bands such as $1,001 - $15,000; $15,001 - $50,000. Yield Theory keeps those ranges instead of inventing a midpoint, exact trade size, or return.
How complete is DGX congressional-trade coverage?
This snapshot covers every machine-readable House and Senate periodic transaction report for 2025 and 2026 (178 members). Image-only House filings and paper Senate filings are not included, so missing rows are not proof that no other lawmaker traded DGX.
Yield Theory is not affiliated with any elected official. This page uses the 2025–2026 House Clerk and Senate eFD periodic report snapshot generated 2026-11-03. 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 DGX and in what range. Membership is the monthly sourced call, plus a five-minute check when the evidence moves. $39/month or $249/year.
