S-Energy Co.,Ltd.: what insiders have been doing
S-Energy Co.,Ltd., classified in the Energy sector, is a listed company. Its insiders report their share dealings to DART (FSS). 4 insiders have disclosed 13 filings since 1 November 2025.
Purchases and sales both appear in the filings: 9 purchases (3 insiders, €3.7M) and 1 sale (1 insider). The amount is not disclosed for 6 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Those buying include 2 board members and 2 chief executives. At €2.6M, the purchase published on 18 March 2026 by 홍성민 is the largest of the period (17.6% of market cap).
In the case of 5 purchases, another manager of the company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster. The clock since the last published purchase (14 August 2026) now reads 87 days. 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.
With 13 filings in twelve months, the company is more active than the median of 7 filings across the 2,655 companies we follow on the same exchange. Our records for S-Energy Co.,Ltd. go back to 2021, with 48 purchases and 2 sales on the open market in total.
For comparison within the same sector, see the insider buying recorded at Compagnie de l'Odet and Scatec ASA. Every figure here comes from the filings published by DART (FSS) and describes the past, not future prices; it is not investment advice.
