Atum Co.,Ltd: what insiders have been doing
Every trade that managers of Atum Co.,Ltd disclose to DART (FSS) is tracked on this page. The company sits in the Technology sector. Over the twelve months to 5 November 2026, 6 filings were filed, from 4 insiders.
The flow runs one way only: 3 insiders bought (5 purchases totalling €1.5M) and nobody sold on the market. The amount is not disclosed for 4 filings. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Those buying include 1 major shareholder and 1 chief executive. 한택수 filed the largest purchase, €1.5M, on 12 May 2026.
The most recent open-market purchase was published on 24 June 2026, 139 days ago. The median gap between a trade and its publication by DART (FSS) is 35 days. The shorter that gap, the sooner other investors can see what insiders have done.
Compared with its exchange (2,656 companies, median 7 filings), a count of 6 filings is below the norm. Looking back to 2023, when coverage begins, insiders filed 7 purchases and 5 sales.
In the same sector, recent insider purchases at Basler Aktiengesellschaft and Lime Technologies AB (publ) also feature in our signals. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
