SET Index Tracks Regional Losses as DELTA and Large-Cap Selling Dent Sentiment

On Friday, Thailand’s SET Index closed the morning trading session at 1,526.50 points, showing a decrease of 12.62 points or 0.82%, with a trading value of THB 37.23 billion.

Bualuang Securities (BLS) noted that the Thai stock market declined during the morning session, in line with the downward trend in Asian equity markets, after having recorded considerable gains.

A major factor weighing on the market was selling pressure in DELTA, which had previously surged significantly. This has raised concerns about the possibility of DELTA being subject to another potential Cash Balance restriction, as well as the risk of being excluded from the SET50 Index, prompting investors to lock in profits and thus tempering the previous momentum.

Meanwhile, there was additional selling in other large-cap stocks after the first-quarter 2026 operating results had been largely factored in by investors. At the same time, selective buying rotated into bank stocks, which managed to gain ground. This trend is seen to reflect renewed interest from foreign investors.

Looking ahead to the afternoon session, Bualuang expects the Thai stock market to continue fluctuating within negative territory. The resistance level is projected at 1,530 points, while the support level is at 1,500 points.
