Laseroptek Co., Ltd.: what insiders have been doing
Laseroptek Co., Ltd. belongs to the Health Care sector. Filings by its managers are published through DART (FSS). Between 2 November 2025 and 2 November 2026, 8 insiders published 17 filings.
The record shows 8 purchases on the open market worth €682k, made by 4 insiders, against 2 sales worth €217k by 2 insiders. No amount is published for 3 filings, which the totals therefore leave out. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Biggest ticket of the year: €362k, bought by 주홍 and made public on 30 March 2026 (1.5% of market cap). On the buying side, the filings list 2 chief executives, 1 board member and 1 senior executive among the declarants.
For context, the typical company on the same exchange (median of 2,655 companies) published 7 filings over the same period, against 17 filings here. Our records for Laseroptek Co., Ltd. go back to 2024, with 23 purchases and 11 sales on the open market in total.
In the case of 5 purchases, another manager of the company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster. The last insider purchase was made public on 23 April 2026, 201 days ago. The median gap between a trade and its publication by DART (FSS) is 13 days. The shorter that gap, the sooner other investors can see what insiders have done.
Other companies in the same sector with recent insider buying flagged by our signals: Dynavox Group AB and UCB. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
