김정훈 (senior executive) discloses dealings in 4 companies, chiefly 옵티코어, GS글로벌 and 온코닉테라퓨틱스. We count 16 filings; the first trade dates from 8 March 2023 and the latest from 13 May 2026.

Both buying and selling appear: 5 purchases worth €264k, against 1 sale. The totals do not cover 3 filings with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. 2026 to date brings 4 purchases and 1 sale.

The median purchase comes to €29k. Measured against the company's value, the median purchase equals 0.012% of market capitalisation, across 3 purchases where it is known. On 3 out of 5 purchases, another insider of the same 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. Ninety days after publication, 3 purchases show a median change of -45.8%, with the price up in 0% of them. These figures describe past trades and do not predict future prices.

The latest filing, published on 13 May 2026, reports a transaction in 옵티코어. The latest purchase dates back some time: it was published 184 days ago, on 17 April 2026. The median gap between a trade and its publication by DART (FSS) is 5 days. Until a filing is published, the market cannot know about the trade. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
