G · 14-day leaderboard — open-market insider flow

No open-market insider buying anywhere in the tracked universe in the last 14 days.

Method: Only open-market purchases (Form 4 code P) count as buy signals; sales are shown only when a notable-sale filter trips (C-suite ≥ $1M, any sale ≥ $10M, ≥25% of the seller's position, or 3+ sellers in 14 days), with the seller's post-sale stake shown for scale. Option exercises, grants, gifts and tax-withholding dispositions are counted as noise. Clusters require ≥3 distinct insiders (by reporting CIK) with purchase transaction dates inside a rolling 14-day window, computed over a 120-day local store of Form 4 rows for the tracked tickers. Signal score (0–100): cluster size (40/50/60), $ bought (5/10/15), buyer seniority (3–10), stake increase ≥10%/25% (5/10), buying within 10% of the 52-week low (10), freshness ≤3 days (5). Every row links to its SEC EDGAR filing. Sources: FMP insider trading (latest feed + per-symbol history + statistics), senate/house disclosures, shares float, batch quotes, earnings calendar — 14 API calls this run.
