Looking for the full Form 4 table — every buyer ranked by dollars bought, with country and role filters? Open the insider leaderboard.
Grades are percentile ranks within each insider type, on that type’s own data: Form 4 trades for corporate insiders, reconstructed STOCK Act disclosures (estimates) for Congress, 13F filings (quarter-end approximations) for funds. Return figures are not comparable across types; the grade is. A grade needs 20 trades (funds: four quarters of filings); until then a card reads “Building track record”. Grades and badges recompute nightly from the day a person entered the tracker. Recomputed Oct 25, 2026.
