Borussia Dortmund GmbH & Co. Kommanditgesellschaft auf Aktien Stock: price and insider trades · Germany

Borussia Dortmund GmbH & Co. Kommanditgesellschaft auf Aktien, founded in 1909, is a Media & Communication company based in Dortmund, Germany. Its directors and officers file their transactions with BaFin. 2 insiders have disclosed 7 filings since 18 October 2025.

Every open-market trade in the period is a purchase: 7 purchases worth €607k, from 2 insiders, and not a single sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. On the buying side, the filings list 1 board member and 1 senior executive among the declarants. The largest single trade was a purchase of €222k by Geske, Bernd, published on 17 December 2025.

For context, the typical company on the same exchange (median of 287 companies) published 5 filings over the same period, against 7 filings here. Over the whole record (from 2025), the tally stands at 11 purchases and no sales.

In all, 2 purchases were made within 30 days of a purchase by another insider of the company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. The clock since the last published purchase (27 August 2026) now reads 51 days. Between a trade and the moment it shows up on BaFin, the median delay is 8 days. Under the Market Abuse Regulation, managers have three business days to notify their trades.
