진코스텍: what insiders have been doing
진코스텍, classified in the Chemicals sector, is a listed company. Its insiders report their share dealings to DART (FSS). Between 2 November 2025 and 2 November 2026, 3 insiders published 5 filings.
Open-market activity splits into 3 purchases totalling €1.4M and 1 sale; 3 insiders sit on the buying side and 1 insider on the selling side. No amount is published for 3 filings, which the totals therefore leave out. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Among those who bought: 1 board member and 1 chief executive. Biggest ticket of the year: €1.4M, bought by 김임준 and made public on 26 March 2026.
For context, the typical company on the same exchange (median of 2,655 companies) published 7 filings over the same period, against 5 filings here. The full history, which starts in 2022, counts 7 purchases against 6 sales.
The most recent open-market purchase was published on 21 October 2026, 19 days ago. The median gap between a trade and its publication by DART (FSS) is 7 days. Until a filing is published, the market cannot know about the trade.
