Both buying and selling appear: 10 purchases, against 4 sales. The amount is not disclosed for 14 filings. 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 1 purchase and 1 sale.
No cluster: in 9 purchases, no other insider of the company bought within 30 days.
The newest entry dates from 11 June 2026: an open-market purchase, in RF머트리얼즈. Between a trade and the moment it shows up on DART (FSS), the median delay is 6 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).
