서현정: trading record in brief
서현정 (chief executive) discloses dealings in 대한과학 to DART (FSS). Over a trading history stretching from 30 March 2021 to 29 October 2026, the count stands at 11 filings.
The open-market record is one-sided, with 11 purchases worth €18k and not one sale. The amount is not disclosed for 10 filings. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Since January 2026: 3 purchases and no sales on the market.
The 8 purchases reviewed show no overlap with other insiders buying the same stock within a month.
On 29 October 2026 came the latest disclosure, an open-market purchase in 대한과학. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
