Thai Stock Market Outlook on 15 May 2026

On Friday, TISCO Securities expects the Thai market to move sideways-up with supporting catalysts from the AI rally trend in the global equity markets and the positive signs from the U.S.-China summit.

However, the analyst urges caution on the volatility of DELTA.

The securities firms set a resistance level for the SET Index at 1,545 – 1,550 points and a support level at 1,520 points for today’s session.

 

Daol Securities stated that while there are volatilities in the Thai bourse, the market may potentially move in a positive territory due to progress in the U.S.-China trade talks, with DELTA remains the leading stock in the market.

Today is the final day for listed companies’ 1Q26 financial reports, which will lead to speculative forces in individual stock according to earnings results.

 

Yesterday, Thailand’s SET Index closed at 1,539.12 points, increased 21.86 points or 1.44%, with a trading value of THB 75.02 billion.
