US insider trading data from Form 4 filings
Form 4 is the filing a company's officers, directors and owners of more than 10% of its shares send to the SEC when they buy or sell its stock, within two business days of the trade. We read the Form 4 filings of the US companies we cover every day and sort each trade by what it actually was: a purchase with the insider's own money, a sale under a trading plan set months in advance, shares taken as pay, or shares the company awarded them.

01 · What we add
Every trade, sorted by what it was
Purchase
Bought on the open market with the insider's own money.
Plan purchase
Bought through a company plan, such as dividends reinvested or an employee stock purchase plan.
Took pay in stock
The insider was owed cash, such as fees or a salary, and took shares instead. The filing's footnote says so.
Sale
Sold on the open market, outside any plan set in advance.
Sale, trading plan
Sold under a Rule 10b5-1 plan set up months before, so the date was fixed in advance.
Grants, option exercises, shares held back for tax and gifts are kept, and they never count as insiders buying or selling.

Insider trades: common questions
What is a Form 4?
A Form 4 is the filing an officer, a director or an owner of more than 10% of a company's shares sends to the SEC when they buy or sell its stock. It is due within two business days of the trade, and it shows the date, the number of shares, the price and how many shares the insider holds afterwards.
What is a Rule 10b5-1 trading plan?
A Rule 10b5-1 plan is set up in advance, at a time the insider holds no inside information, and it fixes when and how many shares will be sold or bought. Trades under it run on the plan's schedule, so the date of a planned sale says little about what the insider thought that day.
Why are purchases and sales kept apart?
Insiders sell for many reasons, such as taxes, a house or spreading out their wealth, and most sales run on plans set in advance. An open-market purchase is rarer: the insider spends their own money at the market price. Sorting each trade by type lets you see which one you are looking at.
How quickly does a new Form 4 show up?
We read new Form 4 filings every day, so a trade filed today appears within a day.
Which companies are covered?
US-listed companies in the S&P 500, S&P MidCap 400 and S&P SmallCap 600, and larger companies based outside the US that file with the SEC. More companies are added as the dataset grows.
