What is Insider Trading?
Understanding legal insider trading and how corporate executives' stock transactions provide investment signals.
Definition
Insider trading refers to the buying or selling of a company's securities by individuals who have access to material, non-public information about the company. There are two types:
Legal Insider Trading
When corporate insiders (executives, directors, employees with >10% ownership) buy or sell shares of their own company and properly report these transactions to the SEC via Form 4 filings.
This is completely legal and happens every day. These transactions are publicly disclosed and can provide valuable insights into how executives view their company's future prospects.
Illegal Insider Trading
When someone trades securities based on material, non-public information obtained through a breach of fiduciary duty or other relationship of trust and confidence.
This is a federal crime punishable by fines and imprisonment. Examples include trading on information about an upcoming merger before it's publicly announced.
What InsiderNode Tracks
Important: We Only Track Legal Insider Trading
InsiderNode exclusively tracks legal, publicly disclosed insider transactions filed with the SEC. We analyze Form 4 filings to identify when executives, directors, and major shareholders buy or sell their company's stock.
These legal transactions can be valuable investment signals because:
- Insiders know their company best — They have access to detailed operational and financial information
- Real money at stake — When executives buy stock with their own cash, they're putting their money where their mouth is
- Historical performance matters — Some insiders consistently outperform the market, while others don't
- Cluster buying is a strong signal — When multiple insiders buy at the same time, it often indicates confidence in the company's prospects
