대진첨단소재: what insiders have been doing
대진첨단소재 belongs to the Chemicals sector. Filings by its managers are published through DART (FSS). In the past year (1 November 2025 to 1 November 2026), 15 filings came from 4 insiders.
On the market, 2 insiders bought (4 purchases) while 2 insiders sold (6 sales totalling €67k). No amount is published for 9 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. 곽윤창 filed the largest sale, €67k, on 12 March 2026, which represents 0.22% of the company's market value. Among those who bought: 1 board member.
The last insider purchase was made public on 15 January 2026, 299 days ago. Between a trade and the moment it shows up on DART (FSS), the median delay is 7 days. The shorter that gap, the sooner other investors can see what insiders have done. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
With 15 filings in twelve months, the company is more active than the median of 7 filings across the 2,655 companies we follow on the same exchange. Over the whole record (from 2025), the tally stands at 10 purchases and 9 sales.
