Planned insider sales
Notices (SEC Form 144) that executives and other insiders file before selling shares, and whether a sale was reported afterwards.
About this data
- What it is
- Before an executive, director or large owner sells restricted or control shares, they file a short notice with the SEC, called Form 144, saying how many shares they plan to sell, through which broker and roughly when. This feed lists those notices, and for each one shows whether a sale was reported afterwards on a Form 4 and how many days later.
- Who files it
- The person selling, or their broker, on the day the sale is placed. Electronic notices start in April 2023.
- How current
- We collect new notices throughout the day on SEC business days.
- Terms
- Form 144The notice an insider or other affiliate of a company files with the SEC before selling restricted or control shares, so the shares can be sold under Rule 144. The notice says how many shares, through which broker, and roughly when.10b5-1 planA Rule 10b5-1 trading plan lets an insider set up future sales in advance, on a schedule or at set prices, at a time when they do not hold inside information. A notice that gives a plan adoption date says the sale is made under such a plan.
- Worth knowing
- A notice is a plan, not a sale: the person may sell fewer shares, later, or not at all. The value is the one the filer typed, at a price they chose, not what the shares sell for. Many sales are routine, made to diversify or pay taxes, or under a 10b5-1 plan set up months earlier. A blank in the last column does not mean no sale: the person may not have to file a Form 4 (an ordinary affiliate does not), the sale may be recent, or the Form 4 may name a different spelling of the person. We match by the filer's number first and by name second. Information, not investment advice.
All of this comes from public filings.

| Filed | Insider | Company | Shares to sellA notice is a plan, not a sale. The person may sell fewer shares, sell later, or not sell at all, and the number of shares is what they expect to sell on the day they file. | ValueThe aggregate market value the filer typed on the notice: the shares times a price the filer chose. It is not what the shares will sell for. | PlanA Rule 10b5-1 trading plan lets an insider set up future sales in advance, on a schedule or at set prices, at a time when they do not hold inside information. A notice that gives a plan adoption date says the sale is made under such a plan. | Expected sale | Sale reportedInsiders who are officers, directors or hold more than 10% report their sales on a Form 4, within two business days. We look for the first Form 4 with an open-market sale by the same person in the same company within 90 days of the notice, and show how many days after the notice it was filed. A blank means we found none: the person may not have sold, may not have to file a Form 4, or the Form 4 may be one we do not have. | Notice |
