# Track Insider Trading

Insider transactions are among the most closely watched signals in the stock market. When a CEO buys shares with personal funds, it signals confidence. When multiple executives sell simultaneously, it can raise concerns. These transactions must be reported to the SEC within two business days on Form 4, making them one of the most timely disclosures available.

Searching for Form 3 (initial ownership), Form 4 (changes in ownership), and Form 5 (annual summary) filings reveals the trading activity of company insiders -- officers, directors, and large shareholders. The pattern of insider activity often tells a story that earnings reports and press releases do not.

This is valuable for event-driven traders who use insider activity as a signal, fundamental analysts looking for confirmation of their thesis, corporate governance researchers studying executive compensation patterns, and journalists investigating potential conflicts of interest. Insider trading data is public but scattered across thousands of filings -- structured search makes it actionable.
