Stone One Public Company Limited: what insiders have been doing
Stone One Public Company Limited belongs to the Chemicals sector. Filings by its managers are published through Thai SEC (Form 59). In the past year (25 October 2025 to 25 October 2026), 24 filings came from 2 insiders.
There is no open-market purchase to report; the filings show 24 sales worth €398k by 2 insiders. One trade stands out by size: a sale of €39k from Krittanan Pingclasai, disclosed on 24 June 2026.
Publication is fast: at least half of the trades appear on Thai SEC (Form 59) on the same day. That lag is the time during which only the insider knows about the trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
For context, the typical company on the same exchange (median of 351 companies) published 3 filings over the same period, against 24 filings here. Our records for Stone One Public Company Limited go back to 2026, with no purchases and 24 sales on the open market in total.
Elsewhere in the same sector, our signals recently picked up insider purchases at Titan and Norske Skog ASA. 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.
