조선내화: what insiders have been doing

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.
With 2 filings in twelve months, the company is quieter than the median of 7 filings across the 2,655 companies we follow on the same exchange. Our records for 조선내화 go back to 2023, with 4 purchases and 9 sales on the open market in total.
