Methodology & FAQ

How We Track SNPS Insider Transactions

Form 4 disclosures are sourced directly from SEC EDGAR and re-ingested on every pipeline cycle. A complete description of transaction-code handling, the open-market vs grant distinction, and the Rule 10b5-1 plan-reference heuristic is documented in the Methodology.

What is an SEC Form 4 filing for SYNOPSYS INC?

Form 4 is a transaction-level disclosure that corporate insiders (officers, directors, and beneficial owners of more than 10% of a registered class of equity securities) must file with the SEC within two business days of any change in their beneficial ownership of SYNOPSYS INC (SNPS) shares.

What is a Rule 10b5-1 trading plan?

Rule 10b5-1 is an SEC rule that lets insiders schedule trades in advance under a written plan, providing an affirmative defense against insider-trading allegations as long as the plan was adopted in good faith and not while in possession of material non-public information. Form 4 rows marked "10b5-1" on this page indicate the underlying trade was executed under such a plan; rows without the badge are discretionary or did not reference a plan in the Form 4 footnotes.

How is "insider buying" different from a stock grant or option exercise?

An insider buy (SEC transaction code P) is an open-market purchase of SYNOPSYS INC (SNPS) stock executed at the prevailing market price using the insider's personal capital. Stock grants (code A) and option exercises (code M) are compensation events, not directional trades; they are tracked separately and excluded from the "conviction" signal because they are not discretionary purchases.

How recent is the data?

Form 4 transactions are typically reported within two business days of execution. Pactolio re-ingests the EDGAR feed on a nightly cycle and reflects new filings on the next ingest run, typically within 24 hours of EDGAR acceptance. The table on this page covers the most recent 1-year window.
