Biodyne Co., Ltd.: what insiders have been doing
Biodyne Co., Ltd., classified in the Health Care sector, is a listed company. Its insiders report their share dealings to DART (FSS). From 23 October 2025 to 23 October 2026, the disclosure feed for Biodyne Co., Ltd. logged 8 filings by 3 insiders.
Only purchases show up on the open market, 6 purchases in all, filed by 3 insiders. The totals exclude 6 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. Among those who bought: 2 board members and 1 chief executive.
The last purchase on record was published on 13 July 2026, which is 118 days ago. The median gap between a trade and its publication by DART (FSS) is 7 days. This delay matters because a trade only becomes useful information once it is public.
With 8 filings in twelve months, the company is more active than the median of 7 filings across the 2,650 companies we follow on the same exchange. Over the whole record (from 2021), the tally stands at 8 purchases and 10 sales.
In the same sector, recent insider purchases at Dynavox Group AB and EssilorLuxottica also feature in our signals. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
