On November 17, 2025, Illumina dumped 1,000,000 shares of GRAL — $79.85M. On December 3, the CEO, CFO, and President sold a combined $7.59M on the same day, all discretionary. Tracenotes' cluster detector would have flagged it that morning. On February 20, 2026, the NHS-Galleri trial missed its primary endpoint and the stock fell roughly 50%.
For three weeks in summer 2021, CEO Ernie Garcia III sold 60,000 shares a day. His father sold $3.6B in parallel. Sixteen months later the stock traded at $3.55 — a 99% drawdown. The same family is selling again, in similar size, at similar prices — this time under a 10b5-1 plan.

Form 4 is the SEC disclosure required when a company insider — an officer, director, or 10% owner — buys or sells the company’s stock. By law these filings must be submitted within two business days of the trade, so they are a near-real-time view of what insiders are doing.
Tracenotes scans EDGAR for new Form 4 filings every six hours, with watchlist tickers prioritized on every run. When a cluster forms (three or more insiders trade in the same direction within 14 days), users tracking that ticker get an email alert in the next Morning Brief.
Three or more distinct insiders buying or selling within a 14-day window. Multi-insider activity is a stronger signal than a single trade because three different people independently reach the same view. Tracenotes excludes pre-scheduled 10b5-1 sales from cluster detection.
Yes. Form 4 filings are public, filed with the SEC, and freely available on EDGAR. We aggregate and surface what is already published. No insider tips, no non-public information.
EDGAR is the source. But you have to know what you are looking for, search ticker by ticker, and read raw XML. Tracenotes does the cluster math, ranks signals by significance, and emails you when patterns form across the tickers you track.
Sourced directly from SEC EDGAR — the same data your broker, an analyst, or a regulator would use. We do not synthesize, infer, or estimate. If a transaction shows up on Tracenotes, the Form 4 is on EDGAR with the same numbers.
