When an executive buys or sells shares of their own company, they cannot do it quietly. Federal law forces them to tell the SEC, fast, and the filing is public the moment it lands. This is corporate insider reporting, and it is completely separate from the congressional kind.
Who counts as an insider
Under Section 16 of the Securities Exchange Act of 1934, an "insider" is:
- An officer of the company, like the CEO or CFO.
- A member of the board of directors.
- Any beneficial owner of more than 10% of a class of the company's stock.
These people are presumed to know more about the business than the public, so the law makes their trades transparent.
The three forms
The two-business-day rule is the key difference from Congress. A Form 4 is due within two business days of the trade, not 45. That makes insider data far more timely than congressional data.
Where to find the filings
Everything is filed electronically on the SEC's EDGAR system at sec.gov. You can search any company and pull its Form 4 history directly. EDGAR is authoritative but bare-bones, so most people use a tracker that turns the raw filings into a readable feed. ChartRead does this for free and pairs each insider buy with a chart read on the ticker.
Not every insider trade is a real signal
This is where most people go wrong. A Form 4 can report several very different things, and only one of them is a strong signal:
- An open-market purchase means the insider spent their own cash to buy shares at the market price. That is the bullish signal worth watching.
- An option exercise or a stock grant is just compensation being collected. It is not a vote of confidence, even though it shows up as shares acquired.
- A sale can mean almost anything: taxes, a house, diversification. Insiders sell for a hundred reasons but buy for essentially one.
Filter for real buys. A tracker that lumps grants and exercises in with cash purchases will make routine compensation look like conviction. The buy that matters is the open-market purchase.
The bottom line
Insider reporting is fast, public, and legally required. The trades themselves are legal, what is illegal is trading on material non-public information, which the SEC polices separately. Used well, a clean Form 4 feed shows you when the people who run a company are putting their own money behind it.
