정광훈: trading record in brief

This profile gathers the share dealings of 정광훈 in 제이엠아이, where the filings describe the role as chief executive. Between 13 December 2022 and 21 October 2026, the trades on record add up to 14 filings.

Purchases make up the whole of the open-market record (12 purchases, €432k). The totals exclude 7 filings filed without an amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price. In 2026 alone, the filings show 8 purchases and no sales.

A typical purchase (the median) is worth €71k. Measured against the company's value, the median purchase equals 0.44% of market capitalisation, across 5 purchases where it is known. The 10 purchases reviewed show no overlap with other insiders buying the same stock within a month. Ninety days after publication, 5 purchases show a median change of -3.0%, with the price up in 40% of them. These figures describe past trades and do not predict future prices.

On 21 October 2026 came the latest disclosure, a transaction in 제이엠아이. The clock since the last published purchase (11 August 2026) now reads 89 days. Filings reach the DART (FSS) feed a median of 7 days after the trade. 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.
