Surasit Chaitrakulthong

Surasit Chaitrakulthong appears in our data through filings on STC Concrete Product Public Company Limited shares, published by Thai SEC (Form 59). Over a trading history stretching from 21 May 2026 to 28 September 2026, the count stands at 36 filings.

Both buying and selling appear: 28 purchases worth €4,558, against 8 sales worth €14k. Taken together, the sales exceed the purchases by €9,502. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.

In size, the median ticket on the buying side is €68. Relative to company size, the median is 0.0007% of market cap (24 purchases with a known value). Across 23 purchases, this insider has always bought alone, with no colleague buying within 30 days. After 7 purchases with a full 90-day history, the hit rate stands at 100% and the median 90-day move at +20.0%. Past outcomes like these are no guarantee of what comes next.

The latest filing, published on 28 September 2026, reports an open-market purchase of €93 in STC Concrete Product Public Company Limited. Publication is fast: at least half of the trades appear on Thai SEC (Form 59) on the same day. The shorter that gap, the sooner other investors can see what insiders have done.
