서상덕

서상덕, listed as chief executive, has filed trades across 2 companies (mainly through DART (FSS)), most often in 에스투더블유 and 흥구석유. Between 19 September 2025 and 29 July 2026, the trades on record add up to 21 filings.

On the open market, the record shows 15 purchases worth €4.8M and 3 sales worth €13.0M. The totals do not cover 10 filings with an undisclosed amount. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Since January 2026: 12 purchases and 3 sales on the market.

Half of the purchases are above €360k and half below. As a share of market capitalisation, the median purchase stands at 0.54%, based on 7 purchases. Clusters matter here: 3 out of 8 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. Ninety days after publication, 6 purchases show a median change of -57.5%, with the price up in 0% of them. Past outcomes like these are no guarantee of what comes next.

On 29 July 2026 came the latest disclosure, a transaction in 에스투더블유. The last insider purchase was made public on 16 July 2026, 94 days ago. The median gap between a trade and its publication by DART (FSS) is 5 days. 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.
