The Insider Sonar flags 3+ insiders buying together, in real time on paid tiers.
Built from public SEC Form 4 filings (open-market transactions; derivative and plan-based transactions may be excluded). Estimated returns compare the close on the trade date to the latest close and are approximations, not audited performance. Records accumulate from when WhaleTrack first observed this insider — earlier trades may exist on SEC EDGAR. Not investment advice. See our Terms.
