Who drives the trading activity in this ticker
A handful of Congress members often explain most of the trading volume in a single ticker. Click through to a member profile to see their wider track record across all tickers. You can combine this with the What-If dashboard to design rules like “only follow trades by my top performers in BRK”.
Members of the US House and Senate must file Periodic Transaction Reports (PTRs) when they trade individual stocks or certain funds. This page aggregates all disclosed BRK trades from those PTR filings and normalizes them into a structured view.
All BRK trades shown here are derived from public PTR disclosures published by the US House and Senate. The Insiders Lab fetches, cleans and deduplicates these filings so you do not have to parse PDFs and XML manually.
You can use Congress trading in BRK as a signal, but it should not replace your own research or risk management. The platform shows who traded BRK, how often and how large, so you can combine that information with fundamentals, technicals and your own playbook.
From this page you can send BRK into the What-If dashboard, filter Congress Signals to BRK only, and drill into the member profiles that account for most of the volume. PRO users can also access backtests, hit ratios and AI Co-Pilot prompts specific to BRK.
You can treat congressional activity in BRK as a structured input into your research process. For example, you might only care when a small group of historically strong members file large BRK trades inside specific market regimes or macro backdrops.
The Insiders Lab helps by cleaning and normalizing public PTR data, making it easy to spot clusters of activity, repeat behaviour by certain members and changes in trading intensity over time. The goal is not to replace your strategy, but to give you a clean lens on how elected officials interact with BRK in their own portfolios.
