All filings by Prateep Tangmatitham on record concern Supalai Public Company Limited. Over a trading history stretching from 26 May 2026 to 26 June 2026, the count stands at 14 filings.

The open-market record is one-sided, with 14 purchases worth €4.7M and not one sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price.

A typical purchase (the median) is worth €300k. Measured against the company's value, the median purchase equals 0.028% of market capitalisation, across 10 purchases where it is known. On 14 out of 14 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. For 8 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 75% of cases, with a median move of +1.8%. This is a record of the past, not a forecast.

On 26 June 2026 came the latest disclosure, an open-market purchase for €85k in Supalai Public Company Limited. The median gap between trade and publication is zero days: most filings appear on the same day. Until a filing is published, the market cannot know about the trade.
