Methodology & FAQ
Methodology: SEC Form 4 Insider Trading Coverage
Data is extracted from Form 4 filings submitted to the SEC EDGAR system for the U.S. large-cap issuer universe. Each row reflects a disclosed transaction by a named corporate insider.
- Who files: Officers, directors, and beneficial owners of more than 10% of any class of the issuer's voting equity must report on Form 4, generally within two business days.
- Transaction types: We classify lines as Buy, Sell, Grant, Exercise, or Other according to the filing. The Transaction Drilldown supports filtering these types independently of the chart bundle.
- Top-15 leaderboard: The static table ranks large-cap issuers by aggregate open-market buy dollar volume over the last 90 days so large-dollar conviction is not drowned out by tiny share-count trades.
- Transaction Drilldown: Pick a ticker or industry to load individual Form 4 rows for your timeframe and type filters; sort columns and follow tickers to institutional-ownership pages for 13F context.
What is SEC Form 4 and who must disclose insider transactions?
Under Section 16 of the Securities Exchange Act of 1934, "insiders"—defined as officers, directors, and beneficial owners of more than 10% of a class of equity—must report transactions to the SEC. These disclosures must be submitted via Form 4 within two business days of the transaction date. Pactolio aggregates these filings specifically for the U.S. large-cap universe to surface institutional-grade conviction signals.
How are insider transactions classified on this page?
Each reported line is mapped to a transaction type: Buy (open-market purchase), Sell (open-market sale), Grant (equity compensation award), Exercise (option exercise), or Other. The Transaction Drilldown lets you choose which types appear in the detailed table; charts and KPIs use a broader default set unless noted.
How is the Top 15 Large-Cap Companies by Insider Buying table ranked?
The static leaderboard ranks large-cap issuers by aggregate dollar value of open-market insider purchases (Buy) over the last 90 days in our database. We use dollar volume rather than raw share count so a large-dollar purchase is not dominated by low-price, small-dollar trades.
How does the Transaction Drilldown work?
Select a company (ticker) or an industry to load individual Form 4 transaction rows from our API for the timeframe and transaction-type filters you choose. Sort any column and use “Show more” to page through results. Ticker cells link to the corresponding institutional-ownership page for 13F holder context.
Why does the default leaderboard emphasize insider buying?
Open-market insider selling is common for liquidity, tax, diversification, and compensation-related reasons and is often a weaker directional signal than discretionary buying. The large-cap top-issuer ranking therefore highlights buy dollar volume; selling and other activity remain visible in charts and in the drilldown when you include those transaction types.
