How does InsiderBeacon score an insider buy?
Out of 100, from who bought, how much their stake grew, the size of the trade, whether other insiders bought within ten days, where the price sat in its 52-week range, and whether it was a first or a routine buy. The score is fixed when the filing arrives. The formula and the research behind it.
Data as of Sep 15, 2026, from SEC EDGAR Form 4 filings: open-market purchases (code P) of $25,000 or more, and open-market sales. Every row links to its filing. Scores summarise what a filing says (how the score works); outcomes are hypothetical, from the first close after the filing, and past results don't predict future ones. Disclaimer
