Dongkuk Steel Mill Company Limited: what insiders have been doing
This page follows insider dealings at Dongkuk Steel Mill Company Limited as filed with DART (FSS), a company from the Chemicals sector. 8 insiders have disclosed 10 filings since 31 October 2025.
Both sides are active: 7 purchases worth €21.0M and 2 sales worth €15.4M, from 6 insiders and 2 insiders respectively. The amount is not disclosed for 5 filings. 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 2 board members, 1 major shareholder and 1 senior executive among the declarants. One trade stands out by size: a sale of €15.4M from 제이에프이스틸인터내셔널유럽, disclosed on 7 May 2026, or 5.3% of market capitalisation.
In the case of 2 purchases, another manager of the company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The last insider purchase was made public on 1 July 2026, 130 days ago. The median gap between a trade and its publication by DART (FSS) is 8 days. This delay matters because a trade only becomes useful information once it is public.
Compared with its exchange (2,655 companies, median 7 filings), a count of 10 filings is above the norm. Over the whole record (from 2023), the tally stands at 43 purchases and 13 sales.
For comparison within the same sector, see the insider buying recorded at Symrise AG and Titan. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
