Halcyon Technology Public Company Limited: what insiders have been doing
Halcyon Technology Public Company Limited is a listed company based in Thailand, founded in 2002. Its insiders report their share dealings to Thai SEC (Form 59). Over the twelve months to 20 October 2026, 9 filings were filed, from 2 insiders.
Purchases and sales both appear in the filings: 7 purchases (2 insiders, €101k) and 1 sale (1 insider, €49k). The net balance comes to €52k on the buying side. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Rattipat Aramwatanapong filed the largest purchase, €78k, on 7 July 2026.
For context, the typical company on the same exchange (median of 347 companies) published 3 filings over the same period, against 9 filings here. The full history, which starts in 2026, counts 7 purchases against 1 sale.
In the case of 2 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 purchase on record was published on 18 September 2026, which is 51 days ago. The median gap between trade and publication is zero days: most filings appear on the same day. The shorter that gap, the sooner other investors can see what insiders have done.
Every figure here comes from the filings published by Thai SEC (Form 59) and describes the past, not future prices; it is not investment advice.
