제이아이테크 Stock: price and insider trades · South Korea

KR·Mcap ₩126.2BChemicals

No insider purchase over the last 90 days. The latest, by 함석헌, was filed 13 Jul 2026.

제이아이테크: what insiders have been doing

제이아이테크 belongs to the Chemicals sector. Filings by its managers are published through DART (FSS). Between 2 November 2025 and 2 November 2026, 3 insiders published 9 filings.

Purchases and sales both appear in the filings: 4 purchases (1 insider) and 3 sales (3 insiders). No amount is published for 7 filings, which the totals therefore leave out. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. On the buying side, the filings list 1 major shareholder and 1 chief executive among the declarants.

The latest purchase dates back some time: it was published 119 days ago, on 13 July 2026. The median gap between a trade and its publication by DART (FSS) is 6 days. The shorter that gap, the sooner other investors can see what insiders have done.

With 9 filings in twelve months, the company is more active than the median of 7 filings across the 2,655 companies we follow on the same exchange. Looking back to 2022, when coverage begins, insiders filed 10 purchases and 8 sales.

Elsewhere in the same sector, our signals recently picked up insider purchases at Symrise AG and Titan. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
