Insider trading alerts: what to track and what to ignore

Insider trading alerts help investors follow public disclosures from company executives, directors and major shareholders. The useful part is not simply knowing that an insider filed something. The useful part is understanding what type of transaction happened, how large it was, who filed it, and whether it is part of a wider pattern.

What should a good insider alert include?

  • The company ticker and market.
  • The insider name and role.
  • The transaction code and whether it was a buy, sell or routine event.
  • The transaction date and filing date.
  • The number of shares, price and disclosed value.
  • A direct link to the original regulator filing.

Why source links matter

Insider filing data can be misunderstood when it is copied without context. A serious alert should always include the original SEC EDGAR or UK RNS source link. Nortis keeps source links attached to every alert so the user can verify the exact filing before making any decision.

Which alerts are usually more interesting?

Open-market purchases are often more informative than routine stock awards because the insider is using personal capital. Cluster activity, where multiple insiders file around the same period, can also be worth a closer look. Senior roles such as CEO, CFO, chair or director can make a filing more relevant, but the original filing still matters.

Which alerts are often routine?

Grants, tax withholding and option mechanics often appear in Form 4 filings even when the insider did not make a discretionary open-market trade. Nortis separates these routine events from open-market buys and sells so users do not treat every filing as the same kind of signal.

How Nortis approaches insider alerts

Nortis monitors SEC Form 4 and UK RNS/PDMR disclosures, classifies the transaction type, highlights cluster activity, adds a plain-English summary, and sends alerts to the dashboard and Telegram. It is designed as a research workflow, not as investment advice.
