Thai Stock Market Outlook on 19 September 2025

On Friday, FSS International Investment Advisory Securities (FSSIA) expects the Thai market to trade sideways within range, as investors are waiting for new supporting factors after having priced in the Federal Reserve rate cut. This causes the SET Index to rebase.

Furthermore, investors are monitoring the formation of the new cabinet.

 

The firm set a resistance level for the SET Index at 1,310, and a support level at 1,290 points for today’s session.

Yesterday, Thailand’s SET Index closed at 1,297.01 points, decreased 9.68 points or 0.74%, with a trading value of THB 44.92 billion.
