How often each insider bought, and what the price did after
Directors and supervisory board members of Dutch listed companies must report every trade in their own company’s shares to the regulator AFM. This page does two separate things with those filings. It counts the open-market purchases each insider reported, and for the insiders whose figures we show it measures what the share price did afterwards. The two stay two: they are never added, multiplied or folded into one score. A combined figure over both — how often someone bought, weighed against what the price did afterwards — would be a new model, and this page does not have one. What stands below is the count; the measured figures are part of the subscription.
Both run on the Dutch AFM register only. The American (SEC Form 4) and German (BaFin) filings on the register page are facts without scores; we keep no per-insider aggregate and no insider page for them, so they can appear in neither list here.
This page is free to read, and it stops after 5 rows. Those are the 5 insiders with the most reported open-market purchases, out of 334. Reading the whole list, and the page behind every filer, is part of the subscription. So is the measured buy-following figure next to each name, over five windows and with its reference beside it. What that costs is on the pricing page.
Open-market buys per insider
5 of 334Shown here: the 5 insiders with the most reported open-market purchases, of 334 who have ever reported one. The register holds 945 insiders in all; the other 611 filed only other kinds of transaction and cannot appear in a count of purchases. Every filing behind these counts is in the register.
This counts filings, not money and not time. An insider who bought a small amount every month stands above one who bought once for many times the sum; the amounts are in the register and are not what this list orders on. The count runs over the whole register at once, not over a recent window — the first and last transaction next to every line say when that activity was.
