Thailand’s SET Index closed the morning session at 1,403.52, representing a decline of 29.47 points or 2.06%, with a trading value of THB 33.87 billion. The downward trend was in line with the regional markets.
According to Mr. Phoowadol Phoosodngern, an investment strategist at Bualuang Securities, escalating tensions in the Middle East—particularly surrounding a 48-hour deadline imposed by the U.S. President—prompted investors to reduce risk exposure.
Large-cap equities came under selling pressure, with shares such as DELTA, ADVANC, TRUE, AOT, GULF, CPN, CPALL, KTB, PTT, and BDMS all contributing to weight on the index. The sell-off was broad-based, affecting multiple sectors.
In contrast, shares in upstream energy, including PTTEP and BANPU, as well as companies expected to benefit from supply disruptions—such as PTTGC, IVL, KSL, STGT, and STA—recorded gains despite the market’s overall downturn.
Looking to the afternoon trade, the Thai bourse is expected to continue moving in negative territory. While no new drivers are anticipated for the remainder of the session, investors are closely watching developments in the Middle East.
The brokerage states that a rebound could occur if there are signs of easing tensions, which may result in a milder loss compared to the morning. The SET Index is expected to move within a range of 1,390 to 1,420 points.
