Returns the stock trades disclosed by members of Congress (the STOCK Act financial disclosures), filtered by a stock OR by a specific politician.
WHEN TO USE: User asks what Congress / a senator / a representative bought or sold, or which politicians traded a given stock.
Examples:
- "What stocks did Nancy Pelosi trade?"
- "Has any member of Congress bought NVDA?"
- "Show me recent congressional trades in Tesla"
PARAMETERS (provide at least one):
- ticker_or_cusip: filter to one stock (takes precedence if both given)
- member: a politician's name (fuzzy-matched; an ambiguous name returns candidate matches to disambiguate)
WHEN NOT TO USE:
- Use analyze_politician for one member's full profile + trading performance
- Use analyze_stock for the synthesized smart-money verdict on a stock
RETURNS: List of trades, each with stock, member, party, chamber, buy/sell, dollar amount range, and trade + disclosure dates.
