Atec Co. Ltd. Stock: price and insider trades · South Korea

Atec Co. Ltd. belongs to the Technology sector. Filings by its managers are published through DART (FSS). 5 insiders have disclosed 25 filings since 22 October 2025.

Every open-market trade in the period is a purchase: 21 purchases worth €1.7M, from 4 insiders, and not a single sale. The totals exclude 8 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. The buyers include 2 board members, 1 major shareholder and 1 senior executive. At €413k, the purchase published on 11 March 2026 by 신승영 is the largest of the period (1.0% of market cap).

In the case of 12 purchases, another manager of the company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The last purchase on record was published on 2 September 2026, which is 69 days ago. Typically, a trade is published a median of 7 days after it takes place. This delay matters because a trade only becomes useful information once it is public.

Compared with its exchange (2,650 companies, median 7 filings), a count of 25 filings is above the norm. Over the whole record (from 2021), the tally stands at 24 purchases and 7 sales.

Elsewhere in the same sector, our signals recently picked up insider purchases at Hanza AB. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
