Blue Industrial Development Co., Ltd. belongs to the Construction sector. Filings by its managers are published through DART (FSS). Between 1 November 2025 and 1 November 2026, 7 insiders published 32 filings.
Purchases and sales both appear in the filings: 11 purchases (5 insiders, €20.9M) and 6 sales (3 insiders). The amount is not disclosed for 16 filings. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay.

With 32 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 16 purchases against 6 sales.
The latest purchase is recent: it was published 12 days ago, on 28 October 2026. The median gap between a trade and its publication by DART (FSS) is 7 days. Until a filing is published, the market cannot know about the trade.
This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
