Methodology

From go-live

1. 1. Source. SEC EDGAR Form 4 filings, checked every three minutes.
2. 2. Qualification. Open-market purchase (transaction code P) of at least $100,000 in total by an officer or director; issuer listed on the NYSE or Nasdaq for at least six months with a market capitalization of at least $300 million at filing; filing date equal to the (last) transaction date in ET. Excluded: purchases under 10b5-1 plans, private transactions, SPACs, and companies that completed a SPAC or reverse merger less than six months before the filing. Indirect holdings via a trust, fund or spouse are included and labeled.
3. 3. Alert. Sent at the moment the filing appears on the dashboard, one per filing.
4. 4. Entry. The regular-session opening price of the first trading day after the filing. If unavailable after the nightly run, the entry stays pending and is flagged; no substitute price is used.
5. 5. Holding period and exit. The exit is the close of day 252: 252 NYSE trading days after the entry day (day 0), at that day's official closing price. If that close is unavailable, the last available official close before it, flagged.
6. 6. Sell signal. Sent overnight after the close of day 251, before the open of the exit day; the exit is the close of day 252.
7. 7. Portfolio. Equal-weighted average of all positions. From go-live. Open positions use the latest official close and closed positions use the exit price. Returns are adjusted for splits, excluding dividends and costs.
8. 8. History. The August 31 to September 29, 2026 test period has been archived.
