Daesung Industrial Co., Ltd.: what insiders have been doing
Daesung Industrial Co., Ltd. is a Energy company. Its directors and officers file their transactions with DART (FSS). Between 22 October 2025 and 22 October 2026, 13 insiders published 22 filings.
Open-market activity splits into 16 purchases totalling €4.7M and 5 sales totalling €199k; 12 insiders sit on the buying side and 3 insiders on the selling side. No amount is published for 5 filings, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Among those who bought: 9 board members, 2 chief executives and 1 senior executive. Biggest ticket of the year: €2.4M, bought by 김영대 and made public on 4 May 2026 (2.4% of market cap).
In all, 14 purchases were made within 30 days of a purchase by another insider of the company. Purchases made close together by different insiders form what is called a cluster. The last insider purchase was made public on 5 August 2026, 97 days ago. The median gap between a trade and its publication by DART (FSS) is 10 days. That lag is the time during which only the insider knows about the trade.
With 22 filings in twelve months, the company is more active than the median of 7 filings across the 2,650 companies we follow on the same exchange. Looking back to 2021, when coverage begins, insiders filed 22 purchases and 5 sales.
In the same sector, recent insider purchases at ASTA Energy Solutions AG and Compagnie de l'Odet also feature in our signals. Source: insider filings from DART (FSS). Past trades are no guide to future returns.
