Entry is the close on the day after publication, the first price a reader could act on. Prices in the listing currency. Past moves are not a forecast.
조현준, listed as chief executive, has filed trades across 3 companies (mainly through DART (FSS)), most often in 효성, 현대자동차 and 효성티앤씨. We count 25 filings; the first trade dates from 2 September 2022 and the latest from 7 October 2026.
The open-market side counts 10 purchases for €519k alongside 4 sales. The totals exclude 12 filings filed without an amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price. 2026 to date brings 2 purchases and 1 sale.
2 out of 10 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster.
The latest filing, published on 7 October 2026, reports a transaction in 효성. The most recent open-market purchase was published on 10 April 2026, 191 days ago. Typically, a trade is published a median of 7 days after it takes place. This delay matters because a trade only becomes useful information once it is public. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
