Insider trading data from 30+ official regulatory sources
Every transaction on InsiderLens is sourced directly from mandatory regulatory filings. Never scraped, never estimated, never delayed.
How insider transactions are regulated worldwide
In the United States, Section 16 of the Securities Exchange Act of 1934 requires corporate insiders (officers, directors, and holders of more than 10% of a company's shares) to report transactions to the SEC via Form 3 (initial holdings), Form 4 (changes in ownership), and Form 5 (annual summary). Filings are publicly available within 2 business days on the EDGAR system. In the European Union, the Market Abuse Regulation (MAR, Regulation EU 596/2014) Article 19 requires Persons Discharging Managerial Responsibilities (PDMRs) and their closely associated persons to disclose transactions within 3 business days. Each EU member state's national competent authority (NCA) publishes these notifications.
Why insider transactions matter
Academic research consistently shows that insider transactions contain predictive information about future stock returns. Lakonishok & Lee (2001) found that insider purchases in US stocks outperform the market by approximately 7-10% annually. Jeng, Metrick & Zeckhauser (2003) confirmed that insider purchases earn abnormal returns of over 6% per year, while insider sales show no significant predictive power. More recently, Cziraki, De Goeij & Renneboog (2014) showed similar patterns in European markets, with insider purchases in EU-listed firms generating excess returns of 5-8% over 12 months. Cluster purchases, where multiple insiders buy shares within a 14-day window, have been shown by Alldredge & Cicero (2015) to produce even stronger signals, with abnormal returns exceeding 10% over the following quarter.
Data normalization methodology
InsiderLens normalizes insider transaction data from heterogeneous sources into a unified schema. The pipeline processes each filing through 6 stages:
matching filings to companies via ISIN, CIK, LEI, or ticker+exchange pairs
deduplication of insider identities across sources using name normalization (NFKD decomposition, accent stripping)
200+ multilingual role patterns mapped to 11 canonical roles (CEO, CFO, Board Member, etc.)
source-specific codes and keywords mapped to 14 canonical types (Buy, Sell, Grant, Exercise, etc.)
all amounts converted to USD using ECB exchange rates with weekend/holiday lookback
SHA-256 hash per filing to prevent double-counting across overlapping sources
