박찬: trading record in brief
박찬 (chief executive) discloses dealings in 오이솔루션 to DART (FSS). Over a trading history stretching from 6 May 2021 to 1 October 2026, the count stands at 35 filings.
In open-market terms, that means 4 purchases worth €806k on one side and 9 sales worth €1.3M on the other. No amount is published for 9 filings, which the totals therefore leave out. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Since January 2026: 2 purchases and 6 sales on the market.
Clusters matter here: 2 out of 4 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster.
The record was last updated on 1 October 2026 with an open-market sale in 오이솔루션. The latest purchase dates back some time: it was published 215 days ago, on 8 April 2026. Typically, a trade is published a median of 6 days after it takes place. Until a filing is published, the market cannot know about the trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Source: insider filings from DART (FSS). Past trades are no guide to future returns.
