SET Index Demonstrates Marginal Gains as Investors Await Key Catalysts and Economic Data

On Wednesday, Thailand’s SET Index closed the morning trading session at 1,593.03 points, showing an increase of 1.79 points or 0.11%, with a trading value of THB 39.20 billion.

Pi Securities wrote that the SET Index remained stable in the morning, with stock movements in the positive territory, mainly supported by gains in DELTA. However, if the impact from the tech giant is excluded, the index would be seen as marginally in the negative zone.

Overall, the market lacks new supporting factors after having already priced in developments regarding peace negotiations between the United States and Iran. The SET Index had rebounded approximately 3.5% from its recent lows over the past two days.

The market faced selling pressure in PTTEP, weighing the benchmark down by around 0.6%. There was also notable selling in MRDIYT, THAI, and TFG after a strong rally on Tuesday, as the group was included in the SET50 Index calculation for the second half of the year, leading to some profit-taking in the trading session.

For the afternoon, the Thai bourse is expected to remain stable within a narrow range as investors wait for second-quarter 2026 earnings releases from listed companies, as well as U.S. labor market data to be announced later this week.

Support is assessed at 1,590 points with resistance at 1,605 points.
