유디엠텍: what insiders have been doing

Every trade that managers of 유디엠텍 disclose to DART (FSS) is tracked on this page. The company sits in the Technology sector. The last twelve months, up to 2 November 2026, brought 4 filings signed by 2 insiders.

Purchases and sales both appear in the filings: 1 purchase (1 insider) and 3 sales (2 insiders). The amount is not disclosed for 4 filings. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay.

The last purchase on record was published on 31 March 2026, which is 224 days ago. Between a trade and the moment it shows up on DART (FSS), the median delay is 9 days. Until a filing is published, the market cannot know about the trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.

Compared with its exchange (2,655 companies, median 7 filings), a count of 4 filings is below the norm. The full history, which starts in 2024, counts 9 purchases against 6 sales.

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