Members of Congress trade individual stocks. Their committee assignments give them access to information ordinary investors don't have. Since 2012, federal law requires them to disclose their trades publicly.

The Politicians tab pulls in those disclosures so you can see the data — and decide what, if anything, to make of it. This lesson is educational, not advisory. Congressional trading data is public, structured, and increasingly studied in the academic literature.

Learning to read it is a skill in financial-data literacy, in the same way reading 13F filings or insider Form 4s is a skill. The lesson does NOT endorse copying any particular politician's trades, and does NOT make claims about specific individuals beyond brief factual reference where required. The STOCK Act requires members of Congress (and certain senior staff and executive-branch officials) to file a Periodic Transaction Report for any securities transaction over $1,000.
