The Securities and Exchange Commission (SEC) says it is investigating filing documentation for share purchases in six Thai companies since 2021 by a mystery investor who last week reported acquiring a 7% stake worth 32 billion baht in True Corporation.
The regulator said the purchases of shares in the companies listed on the Stock Exchange of Thailand were made between 2021 and 2025 by an investor it named as Supaporn Pimphong.
