This profile gathers the share dealings of 유성준 in 대진첨단소재, where the filings describe the role as chief executive. In total, 8 filings cover trades dated from 6 March 2025 to 5 June 2026.

The open-market side counts 2 purchases alongside 5 sales. The totals exclude 7 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. In 2026 alone, the filings show no purchases and 4 sales.

On 5 June 2026 came the latest disclosure, a transaction in 대진첨단소재. The most recent open-market purchase was published on 12 March 2025, 606 days ago. The median gap between a trade and its publication by DART (FSS) is 7 days. That lag is the time during which only the insider knows about the trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Source: insider filings from DART (FSS). Past trades are no guide to future returns.
