Sejong Telecom, Inc.: what insiders have been doing
This page follows insider dealings at Sejong Telecom, Inc. as filed with DART (FSS), a company from the Telecom sector. The last twelve months, up to 31 October 2026, brought 20 filings signed by 2 insiders.
Both sides are active: 14 purchases worth €5.2M and 2 sales, from 1 insider and 1 insider respectively. The totals exclude 12 filings filed without an amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. 세종 filed the largest purchase, €2.3M, on 9 April 2026, which represents 4.8% of the company's market value. Those buying include 1 major shareholder.
With 20 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 2021), the tally stands at 19 purchases and 10 sales.
The clock since the last published purchase (31 August 2026) now reads 70 days. Between a trade and the moment it shows up on DART (FSS), the median delay is 3 days. This delay matters because a trade only becomes useful information once it is public.
Every figure here comes from the filings published by DART (FSS) and describes the past, not future prices; it is not investment advice.
