2 insiders bought €248k of shares over the last 90 days, the latest by ALBERT DüRR, filed 16 Oct 2026.
Cluster: 2 buyers in 30 daysThis page follows insider dealings at Erbud S.A. as filed with KNF, a company from the Industrials sector. 3 insiders have disclosed 13 filings since 22 October 2025.
Every open-market trade in the period is a purchase: 4 purchases worth €269k, from 2 insiders, and not a single sale. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Biggest ticket of the year: €225k, bought by DGI Fundacja Rodzinna and made public on 30 September 2026 (0.35% of market cap).
For context, the typical company on the same exchange (median of 553 companies) published 3 filings over the same period, against 13 filings here. Since 2025, the database holds 4 purchases and no sales by insiders of the company.
In all, 1 purchase was made within 30 days of a purchase by another insider of the company. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The most recent open-market purchase was published on 16 October 2026, 7 days ago. Between a trade and the moment it shows up on KNF, the median delay is 1 day. For comparison, MAR article 19 gives managers three business days to notify a trade.
This summary is built from KNF disclosures alone and does not predict where the share price will go.
Entry is the close on the day after publication, the first price a reader could act on. Prices in the listing currency. Past moves are not a forecast.
This score ranks the purchase within its own market. A position size is suggested only on the venues of the backtested strategy universe; elsewhere, signals stay on watch. Not investment advice.
Transparent value + quality ranking, distinct from the insider signal.
