About InsiderRadar

Why we built this and what we're trying to do.

InsiderRadar is a free SEC insider trading and institutional fund flow tracker. We built it because the data was always public — it just wasn't accessible. SEC EDGAR publishes every Form 4 filing within hours of submission. Hedge fund compliance desks monitor it daily. Retail investors had no clean way to see it without paying $200/month to WhaleWisdom or Fintel.

We changed that. Type in any US stock ticker and see every insider trade from the last 90 days — who bought, who sold, how much, at what price, and whether it was a genuine open-market purchase or just an automated stock award. The data comes directly from SEC EDGAR. No intermediaries, no markup, no subscription.

We also track 13F institutional holdings — the quarterly disclosures that reveal exactly what every major hedge fund owns. Search any fund by name to see their latest portfolio.
