Insider Radar reads SEC Form 4 filings every morning and surfaces the one signal that matters: insiders buying their own stock on the open market. It filters out grants and option exercises, flags clusters where multiple insiders buy the same ticker, and ranks each by role (CEO/CFO/director/10% owner) and dollar size. Includes notable discretionary insider selling. Not investment advice.
Track what insiders and 13 top funds, from Berkshire to Pershing Square, are buying and selling, straight from SEC filings. Fund-by-fund 13F changes, consensus buys, any-ticker lookup and insider red flags, every number linked to its source.
Say “dashboard” and see the deals that actually closed this week — 8-K Item 2.01: acquired or sold, target, counterparty, amount — each row linked to EDGAR.
Pick a fund or a ticker and get what top investors bought, sold or exited last quarter, plus where several funds agree. Built from live 13F filings with source links. Public data only, not investment advice.
Get a fast verdict before checkout — spot overpriced, risky, or impulse buys and skip the purchases you'd regret.
