Filings by 김성철 span 2 companies, the busiest being 서진시스템 and 케이티. The record holds 4 filings, for trades running from 5 July 2024 to 8 May 2026.

On the open market, the record shows 3 purchases and 1 sale worth €243k. The totals do not cover 3 filings with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. 2026 to date brings 2 purchases and 1 sale.

1 out of 3 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

Most recently, on 13 May 2026, the filings show an open-market purchase in 케이티. Between a trade and the moment it shows up on DART (FSS), the median delay is 6 days. That lag is the time during which only the insider knows about the trade. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
