JAYAMAS MEDICA INDUSTRI Tbk, PT: what insiders have been doing
Headquartered in Indonesia, JAYAMAS MEDICA INDUSTRI Tbk, PT is a listed company. Filings by its managers are published through OJK / IDX. In the past year (24 October 2025 to 24 October 2026), 6 filings came from 5 insiders.
The flow runs one way only: 5 insiders bought (6 purchases totalling €141k) and nobody sold on the market. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. One trade stands out by size: a purchase of €61k from Louis Krisnadi Hartanto, disclosed on 15 July 2026, or 0.022% of market capitalisation. Among those who bought: 4 senior executives and 1 board member.
In all, 4 purchases were made within 30 days of a purchase by another insider of the company. Purchases made close together by different insiders form what is called a cluster. The last purchase on record was published on 29 July 2026, which is 86 days ago. Filings reach the OJK / IDX feed a median of 5 days after the trade. Until a filing is published, the market cannot know about the trade.
Across the 246 companies tracked on its exchange, the median is 3 filings; at 6 filings, this issuer sits above that mark. Looking back to 2026, when coverage begins, insiders filed 6 purchases and no sales.
Every figure here comes from the filings published by OJK / IDX and describes the past, not future prices; it is not investment advice.
