Thai Stock Market Outlook on 19 August 2025

On Tuesday, FSS International Investment Advisory Securities expects the Thai market to trade sideways within range, as the market slowed down after a significant gain last week, causing the market to alternate between moving sideways and rebase.

The securities firm recommends investors closely monitor Thailand political situation, especially the trial of Prime Minister Paetongtarn Shinawatra’s audio clip case in late August, which could impact the cabinet.

 

The firm set a resistance level for the SET Index at 1,250 and a support level at 1,235 points for today’s session.

Yesterday, Thailand’s SET Index closed at 1,242.31 points, decreased 17.11 points or 1.36% with a trading value of THB 39.29 billion.
