SET Index Trends Downward as DELTA Selloff Pressures Sentiment

On Friday, Thailand’s SET Index closed the morning trading session at 1,574.42 points, showing a decrease of 10.64 points or 0.67%, with a trading value of THB 30.45 billion.

At the start of today’s session, the Thai stock market initially moved higher but later shifted into negative territory, with analysts at FSS International Investment Advisory Securities (FSSIA) noting an absence of new positive drivers.

The brokerage noted that the recent agreement between the United States and Iran to end the conflict and reopen the Strait of Hormuz for shipping for 60 days, combined with a hawkish outcome from the latest Federal Reserve meeting, has already been factored into market sentiment.

Domestic trading saw pressure, primarily from selling in DELTA. This followed projections of a slowdown in second-quarter 2026 earnings growth for the company. FSSIA anticipates quarter-on-quarter figures to weaken, despite expectations of year-on-year growth. Earlier forecasts had anticipated growth on both a quarterly and yearly basis. Meanwhile, S&P’s decision to maintain Thailand’s credit rating at BBB+ had little market impact.

For the afternoon session, FSSIA expects the market to remain under pressure, with direction tied closely to DELTA’s share price performance. A drop below THB 340 for the stock could prompt further declines. Support levels are identified at 1,575-1,570, while resistance is pegged at 1,580-1,590.
