W. Stammeijer: trading record in brief
This profile gathers the share dealings of W. Stammeijer in Koninklijke KPN N.V. We count 11 filings; the first trade dates from 1 June 2023 and the latest from 23 April 2026.
Every open-market trade on record is a purchase: 10 purchases worth €159k, and no sale. The totals exclude 7 filings filed without an amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. So far in 2026, the count stands at 3 purchases and no sales.
Half of the purchases are above €50k and half below. Of 3 purchases, 3 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster.
The latest filing, published on 23 April 2026, reports an open-market purchase in Koninklijke KPN N.V. These figures are compiled from regulatory filings published by AFM. They describe what insiders did and are not a recommendation.
