정찬수

정찬수 (chief executive) discloses dealings in 2 companies, chiefly 디에이테크놀로지 and 라온로보틱스. Over a trading history stretching from 31 July 2025 to 14 October 2026, the count stands at 4 filings.

Purchases make up the whole of the open-market record (3 purchases, €708k). No amount is published for 1 filing, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. 2026 to date brings 3 purchases and no sales.

Of 3 purchases, 2 formed part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

Most recently, on 14 October 2026, the filings show a transaction in 디에이테크놀로지. The most recent open-market purchase was published on 14 May 2026, 164 days ago. Between a trade and the moment it shows up on DART (FSS), the median delay is 6 days. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
