고승범

고승범 (chief executive) discloses dealings in 2 companies, chiefly 비케이홀딩스 and SK하이닉스. We count 14 filings; the first trade dates from 14 March 2023 and the latest from 6 May 2026.

On the market, this insider has only ever bought: 3 purchases. 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. In 2026 alone, the filings show 2 purchases and no sales.

Clusters matter here: 1 out of 3 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

Most recently, on 6 May 2026, the filings show an open-market purchase in SK하이닉스. The median gap between a trade and its publication by DART (FSS) is 27 days. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
