Who trades how
Each fund's 13F book placed by turnover (how much of the book changes in a year) and concentration (share of the book in its 10 largest companies). Bubble size is the 13F book. Patient, concentrated owners sit top-left; fast, diversified books sit bottom-right. Click a fund to open its page.

Stake and insider filings by the 25 funds. Activist 13Ds and Form 4 trades arrive weeks to months before the matching 13F; passive 13Gs usually arrive with it. "Head start" is the days between this filing and the 13F that covers the same quarter.
Filings per month
Congress trades
Stock trades reported by House and Senate members (STOCK Act reports), grouped by the month they were filed, which is when the public could first see them. Blue = more buying than selling, red = more selling. Counts are used instead of dollars because amounts are reported as ranges and a few large trades dominate.
