Getting Started
What is Insider Trading Data?
Insider trading refers to the buying or selling of a company's stock by individuals with access to non-public information about the company. While illegal insider trading involves trading on material, non-public information, legal insider trading occurs when corporate insiders—such as CEOs, CFOs, and directors—buy or sell stock in their own companies and report these transactions to the SEC.

Interpreting the Data
While insider trading data can provide valuable insights, it's important to consider the context of each transaction. Insiders may sell shares for various reasons unrelated to their view of the company's prospects (e.g., diversification, tax planning). However, insider buying is often considered a stronger signal, as insiders typically only buy when they believe the stock is undervalued.
Note: Insider trading data should be used as one of many factors in your investment research. Past insider trading patterns do not guarantee future stock performance.
