최승훈: trading record in brief

최승훈, listed as chief executive, has filed trades across 2 companies (mainly through DART (FSS)), most often in 대성미생물 and 기아. The record holds 9 filings, for trades running from 1 April 2026 to 1 June 2026.

On the market, this insider has only ever bought: 9 purchases, €53k in total. The totals exclude 5 filings filed without an amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.

The median purchase comes to €13k. Relative to company size, the median is 0.061% of market cap (4 purchases with a known value). On 3 out of 4 purchases, another insider of the same company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster. For 4 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 0% of cases, with a median move of -5.2%. These figures describe past trades and do not predict future prices.

The latest filing, published on 1 June 2026, reports an open-market purchase in 대성미생물. Between a trade and the moment it shows up on DART (FSS), the median delay is 1 day. This delay matters because a trade only becomes useful information once it is public. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
