The period balance: money in, money out
In the Form 4 filings submitted between Oct 27, 2025 and Aug 17, 2026 there is not one open-market purchase of Lockheed Martin Corporation: 7 sales worth $4.0M and zero dollars bought. Of those 7 open-market trades, 4 arrive with no usable amount —the filing reports no price, or reports one out of scale and the derived amount is voided—: they count in the trade count and add zero dollars here.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like Lockheed Martin Corporation's is the norm in the S&P 500, where much of the pay comes as stock. It is not a recommendation to buy or sell: it is what was filed.

Who has traded
Over the 15 months of history, 12 distinct people or entities have filed Lockheed Martin Corporation transactions: none bought on the open market and 6 sold. Counted by CIK, the fixed number the SEC gives each filer, and not by name, which each filer types their own way.
Of the 6 who sold on the open market (7 sales in all), the three biggest sellers account for $4.0M of the $4.0M: 100% of the money in three people.

How to read this data
None of the 7 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. Lockheed Martin has no open-market purchase (code P) in the history, the most common case in the S&P 500: insiders are already paid in stock. The latest filing is from Aug 17, 2026, and a Form 4 arrives up to two business days after the trade.
20 of the 20 rows in the table carry footnotes from the Form 4 itself, folded into the code column and copied verbatim; a row with no footnote means the filing has none.

- Who really moves the market: the types of investorWho sits on the other side of each order, and where a company's own insiders fit among them.
- Supply, demand and price: why it rises and falls constantlyHow a piece of news ends up inside the price, and why the reaction to a filed sale is rarely the one you would expect.
