ADBiotech Co., Ltd.: what insiders have been doing

ADBiotech 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, 9 insiders published 19 filings.

Open-market activity splits into 11 purchases and 5 sales; 7 insiders sit on the buying side and 5 insiders on the selling side. No amount is published for 16 filings, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. On the buying side, the filings list 4 major shareholders and 1 chief 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 19 filings here. Since 2021, the database holds 18 purchases and 34 sales by insiders of the company.

The latest purchase dates back some time: it was published 144 days ago, on 18 June 2026. Filings reach the DART (FSS) feed a median of 7 days after the trade. That lag is the time during which only the insider knows about the trade.

Elsewhere in the same sector, our signals recently picked up insider purchases at Dynavox Group AB and UCB. Source: insider filings from DART (FSS). Past trades are no guide to future returns.
