Overview Tab

The Overview tab provides an aggregate view of congressional disclosure activity for the selected period. It includes summary figures for total trades, buy and sell amounts, followed by three sections:

  • Sector Allocation Heatmap: Sector distribution of disclosed trades by party and chamber.
  • Amount by Ticker & Sector: Disclosed volume by asset across the full ticker universe.
  • Top 20 Politicians: Top politicians ranked by total disclosed volume for the selected period.

The tab also includes a Filters panel at the top, which applies to all three sections. It contains a time range selector with preset options (Month, Quarter, Year) and a custom date range picker. The panel is sticky and can be collapsed using the arrow in the top-right corner.
