AMATA.BK is trading at THB 26.75 (+4.90%), but the catalyst remains unclear. - The November 3 close was THB 25.50. - Thailand’s data-center investment rules were due to go to the Cabinet on November 3, a potential industry-wide development; available reporting does not establish that they drove AMATA’s gain. - No confirmed company-specific announcement has been identified, and the supplied market context shows no matching broad-market rally.
