When

Period

How far back the list reaches. Filings arrive days after the trade, so the newest rows always lag a little.

89 decisions over 120 months
Who

Role

The position the person holds at the company, read from the title on the filing. A chief executive who is also a director counts as the chief executive.

The trade

Type of trade

Purchases, sales, or cluster buys: companies where 3 or more insiders bought within 30 days. The number beside each is what that choice would give.

89 decisions over 120 months
The trade

Minimum amount

Hides rows under this value. The amount is the shares traded times the price on the filing.

The trade

Plan

  • Discretionary: they chose to sell that week.
  • Scheduled: a 10b5-1 plan fixed the sale months in advance, so the timing says nothing about what they knew.
  • Not stated: filed before the SEC added the box in April 2023, which is most of the older half of this database.

The trade

Share of their own holding

How much of what they already held the trade moved. Selling a tenth of a stake is not the same act as selling all of it.

Ownership

What the chief executive holds

The value of the chief executive’s stock measured against base salary. The salary comes from the company’s own proxy. Companies with no figure are in neither direction.
