A filing can describe the member, a spouse, a dependent, or a joint asset. Amounts are statutory ranges, not execution prices. See how to read congressional stock-trade disclosures before treating a delayed row as a trading signal.

What LRCX 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.

LRCX congressional trades — FAQ

Who in Congress traded LRCX?

House Clerk and Senate eFD periodic reports for 2025 and 2026 contain 38 verified LRCX rows from 14 members: Alan Armstrong, Byron Donalds, Cleo Fields, David Taylor, and 10 other members. Image-only filings are excluded, and this is not a live brokerage statement.

Does this page show current LRCX 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 LRCX amounts shown as ranges?

Congressional periodic transaction reports use statutory value bands such as $1,001 - $15,000; $15,001 - $50,000; $50,001 - $100,000. Yield Theory keeps those ranges instead of inventing a midpoint, exact trade size, or return.

How complete is LRCX congressional-trade coverage?

This snapshot covers every machine-readable House and Senate periodic transaction report for 2025 and 2026 (176 members). Image-only House filings and paper Senate filings are not included, so missing rows are not proof that no other lawmaker traded LRCX.

Yield Theory is not affiliated with any elected official. This page uses the 2025–2026 House Clerk and Senate eFD periodic report snapshot generated 2026-10-06. 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 LRCX and in what range. Membership is the monthly sourced call, plus a five-minute check when the evidence moves. $39/month or $249/year.
