Insider transactions and SEC Form 4

SEC Form 4 is a disclosure filed by company insiders — directors, officers, and beneficial owners of more than 10% of a company’s equity — when they buy, sell, or exercise options in the company’s securities. It must generally be filed within two business days of the transaction and appears in the SEC EDGAR system.

Each filing shows the insider’s name and role, the transaction date, price, share count, and the holding before and after, so you can see whether insiders are building or reducing a stake.

Form 4 is a record of transactions that happened. It is separate from the law against trading on material non-public information. An insider can lawfully buy or sell company stock and report it on Form 4; the illegal act is trading based on undisclosed inside information.

Many insider sales are pre-arranged under planned trading programs, and option grants are often set by a board compensation committee rather than chosen by the insider. Aerarium Research keeps the filing source visible so each transaction can be read in context.

An insider sale is not proof a company is in trouble. Insiders sell for diversification, taxes, or personal reasons, and routine sales are common. A single buy is not a signal that a price will rise — even insiders time the market poorly.

The more meaningful pattern is consistent, unusual activity across several insiders, not one transaction. Form 4 also covers only company insiders, not large institutional flows, which are disclosed elsewhere.
