AMATA.BK is trading at THB 26.75, up 4.90% from the November 3 close of THB 25.50; no confirmed company-specific announcement explains the move. - Thailand’s SET Index gained 0.74% on November 5, offering broader-market support but not establishing a direct catalyst for AMATA.BK’s larger rise. - Proposed data-center rules and possible industrial-estate demand are relevant background, but neither is confirmed as a driver. The reason remains uncertain.
