Sumpan Vongphan

Sumpan Vongphan appears in our data through filings on Tirathai Public Company Limited shares, published by Thai SEC (Form 59). Between 29 May 2026 and 10 September 2026, the trades on record add up to 12 filings.

No open-market sale appears; the market trades are 12 purchases worth €452k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket.

In size, the median ticket on the buying side is €33k. Relative to company size, the median is 0.053% of market cap (4 purchases with a known value). 7 out of 11 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster. Ninety days after publication, 7 purchases show a median change of -6.3%, with the price up in 29% of them. They describe history only and say nothing certain about the share price ahead.

The record was last updated on 10 September 2026 with an open-market purchase (€30k) in Tirathai Public Company Limited. The median gap between trade and publication is zero days: most filings appear on the same day. That lag is the time during which only the insider knows about the trade. This summary is built from Thai SEC (Form 59) disclosures alone and does not predict where the share price will go.
