Tracking 56 insiders so far; 11 have scorable discretionary buys (rankings need a reported buy price and a current close — sells, 10b5-1 plan trades, and unpriceable rows don't rank). The roster grows daily as new Form 4 filings are observed. Built from public SEC Form 4 filings (open-market transactions). Returns compare the reported trade price to the latest daily close and are approximations, not audited performance; records accumulate from when WhaleTrack first observed each insider. Past performance does not predict future results. Not investment advice. See our Terms.
