제이오: what insiders have been doing

This page follows insider dealings at 제이오 as filed with DART (FSS), a company from the Chemicals sector. 5 insiders have disclosed 6 filings since 2 November 2025.

Only sales appear on the open market, 6 sales in all, filed by 5 insiders. The totals do not cover 6 filings with an undisclosed amount.

Typically, a trade is published a median of 1 day after it takes place. That lag is the time during which only the insider knows about the trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.

Compared with its exchange (2,655 companies, median 7 filings), a count of 6 filings is below the norm. Looking back to 2023, when coverage begins, insiders filed 25 purchases and 29 sales.

Other companies in the same sector with recent insider buying flagged by our signals: Symrise AG and Titan. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
