Net disclosed flow by ticker for Cynthia M. Lummis
NetTickerThe issuer as the ticker's newest trade names it, without the parts that repeat the row: a trailing “(TICKER)” that is the row's ticker, the stock code “[ST]” when it is the row's type (“Stocks (including ADRs)” in the House Clerk's list of asset type codes), and a trailing “Common Stock” or “Ordinary Shares”. No code is shown as words here, since the row nets every trade in the ticker. A name that differs from the filing in any other way is a button: its note gives the text as filed and its code. The filing itself is the exact record.net disclosed flow = sum of purchase bucket bounds minus sum of sale bucket bounds, as a net range net = [pL−sU, pU−sL]. A side with no rows has summed zero — a fact, not an absence. A row with any wholly-undisclosed amount on either side is not rankable and sits in the labeled bucket below the ranked rows, never coerced to zeroBuysSellsnet disclosed flow = sum of purchase bucket bounds minus sum of sale bucket bounds, as a net range net = [pL−sU, pU−sL].

Medians are per member across the 69 Senate members with disclosed rows in this build — one observation each, so a high-volume filer does not become the chamber. Statistics describe the filing record, never intent.

No disclosed trades fall inside this member's committee jurisdictions as of their trade dates · 2 trades predate the membership snapshot's validity window and are unanswerable, not cleared.

Additional disclosure analysis

Most-disclosed tickers

No tickers disclosed in the trailing 24 months.

5 reported transactions

Amounts are the ranges in the filing. Purchases and sales are disclosures, not a statement of current holdings.

Published 2026-10-01

Trade date and filing date are retained separately. Late and unparseable records stay identified in the data.

Annual holdings are not in this view

Periodic transaction reports do not establish a portfolio. Annual holdings and reconciliation require annual financial-disclosure records.
