Duk San Neolux Co.,Ltd: what insiders have been doing
Every trade that managers of Duk San Neolux Co.,Ltd disclose to DART (FSS) is tracked on this page. The company sits in the Technology sector. Over the twelve months to 1 November 2026, 13 filings were filed, from 9 insiders.
The record shows 7 purchases on the open market worth €31.9M, made by 7 insiders, against 4 sales worth €16k by 3 insiders. 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. Biggest ticket of the year: €30.9M, bought by 삼성자산운용 and made public on 10 March 2026 (6.2% of market cap). The buyers include 2 major shareholders, 1 board member and 1 senior executive.
Compared with its exchange (2,655 companies, median 7 filings), a count of 13 filings is above the norm. Looking back to 2021, when coverage begins, insiders filed 9 purchases and 22 sales.
The last purchase on record was published on 1 July 2026, which is 130 days ago. Between a trade and the moment it shows up on DART (FSS), the median delay is 6 days. This delay matters because a trade only becomes useful information once it is public.
Other companies in the same sector with recent insider buying flagged by our signals: Basler Aktiengesellschaft and Lime Technologies AB (publ). This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
