Jeong Moon Information. Co., Ltd: what insiders have been doing
Jeong Moon Information. Co., Ltd is a Technology company. Its directors and officers file their transactions with DART (FSS). Between 31 October 2025 and 31 October 2026, 2 insiders published 14 filings.
The flow runs one way only: 2 insiders bought (13 purchases totalling €432k) and nobody sold on the market. The totals exclude 8 filings filed without an amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The largest single trade was a purchase of €192k by 정광훈, published on 29 April 2026, equal to 1.2% of the market capitalisation. Among those who bought: 1 chief executive.
The latest purchase dates back some time: it was published 91 days ago, on 11 August 2026. Typically, a trade is published a median of 7 days after it takes place. This delay matters because a trade only becomes useful information once it is public.
With 14 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. The full history, which starts in 2021, counts 25 purchases against no sales.
Elsewhere in the same sector, our signals recently picked up insider purchases at Basler Aktiengesellschaft and Lime Technologies AB (publ). These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
