Cluster: 2 buyers in 30 days대한과학: what insiders have been doing
This page follows insider dealings at 대한과학 as filed with DART (FSS), a company from the Health Care sector. 3 insiders have disclosed 8 filings since 2 November 2025.
Every open-market trade in the period is a purchase: 8 purchases worth €18k, from 3 insiders, and not a single sale. The totals exclude 7 filings filed without an amount. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Among those who bought: 1 major shareholder, 1 board member and 1 chief executive. One trade stands out by size: a purchase of €18k from 서현정, disclosed on 21 April 2026, or 0.11% of market capitalisation.
The most recent open-market purchase was published on 29 October 2026, 12 days ago.
With 8 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. The full history, which starts in 2021, counts 19 purchases against no sales.
In the same sector, recent insider purchases at Dynavox Group AB and UCB also feature in our signals. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
