What company insiders bought

Why buying and selling are not symmetrical. An executive sells for any number of reasons: a house, a tax bill, simple diversification. There is one reason to spend your own money buying more of the company you already work for. That asymmetry is why the purchases come first here and why most of what a Form 4 reports is left out entirely.

Only open market purchases and sales appear. A grant, an option exercise, or shares surrendered to cover tax on vesting are compensation, not a decision, and adding them in would show heavy selling at nearly every company all the time. A PLAN chip means the trade was made under a Rule 10b5-1 arrangement set up months earlier, so its timing was not a decision taken that week.

Bought in the last 14 days

Every open market purchase by an officer or director in the last fortnight, most recent first. This is the section to read: a Form 4 is due within two business days of the trade, so this is the freshest thing on the site.

The largest purchases of the last 180 days

Ordered by size, not by date. These are the biggest 12 of the last six months, so the most recent row here is the most recent LARGE purchase, not the most recent purchase. Sorting the date column re-orders these 12 and does not reach further back.

Also ordered by size. Shown for completeness and worth far less attention: there were 208 insider sales in the last fortnight alone, against 35 purchases, and almost all of them are diversification rather than an opinion.

Only individuals appear on these boards. A company filing as a director is taking a strategic position rather than spending its own money on its own employer, which is a different act and one the institutional pages already cover; those filings appear on the security pages instead.

Form 4 is due within two business days of the trade, which makes it the most timely thing on this site: a 13F arrives up to 45 days after a quarter ends. Filings held here cover 2002-02-24 to 2036-08-03. Ten percent owners are excluded from these boards, because they are usually institutions crossing a reporting threshold rather than individuals with a view; they appear on the security pages instead. Nothing here is advice.
