Since 2012, the Stop Trading on Congressional Knowledge (STOCK) Act requires certain federal officials, including members of Congress, to publicly disclose their financial transactions over $1000 in those involving stocks, bonds, and some commodities. This is done through the Periodic Transaction Report (OGE Form 278-T), which must be filed within 30 days of notification of the transaction, but no later than 45 days after the transaction. Political figures on Capitol Hill often have access to information that could influence market movements before it becomes public. By following their trades through this API, you can:
  • Monitor when senators purchase stocks in sectors before favorable legislation
  • Identify House of Representatives members’ trading patterns around regulatory announcements
  • Analyze timing between committee hearings and politician stock transactions
  • Identify politicians with consistently late filings (beyond the 45-day requirement)
