Seoul Electronics & Telecom Co., Ltd.: what insiders have been doing
Seoul Electronics & Telecom Co., Ltd. belongs to the Technology sector. Filings by its managers are published through DART (FSS). Between 10 November 2025 and 10 November 2026, 6 insiders published 10 filings.
Open-market activity splits into 7 purchases totalling €4.2M and 3 sales; 4 insiders sit on the buying side and 2 insiders on the selling side. The totals do not cover 8 filings with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The buyers include 3 major shareholders and 1 board member. At €2.2M, the purchase published on 29 May 2026 by 다온인터내셔널 is the largest of the period.
With 10 filings in twelve months, the company is more active than the median of 7 filings across the 2,630 companies we follow on the same exchange. Over the whole record (from 2021), the tally stands at 9 purchases and 5 sales.
Within a 30-day window, 5 purchases overlapped with buying by a second insider. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The most recent open-market purchase was published on 20 July 2026, 113 days ago. Filings reach the DART (FSS) feed a median of 8 days after the trade. 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: Core Scientific, Inc./tx and Gitlab Inc. Source: insider filings from DART (FSS). Past trades are no guide to future returns.
