Thai Stock Market Declines Amid AI Investment Concerns
The Stock Exchange of Thailand (SET) index dropped by 26.01 points, closing below the 1,520-point threshold as investors reacted to uncertainties regarding artificial intelligence profitability.
On October 30, 2026, the Stock Exchange of Thailand experienced a significant downturn, with the index falling by 26.01 points to close below the 1,520-point level. According to Prachachat Business, the market recorded a total trading value of 73.6 billion baht. The decline was largely attributed to heavy selling pressure on DELTA shares, as investors expressed growing concerns over the long-term return on investment for artificial intelligence technologies. Institutional investors were net sellers, offloading 1.094 billion baht in shares, while foreign investors remained net buyers with 1.058 billion baht in purchases. For residents and expatriates, this market volatility reflects broader global sentiment regarding the tech sector. While the immediate impact on daily life is minimal, those with local investments or interest in the Thai financial climate should monitor the situation closely. TISCO Securities analysts are currently looking for a potential rebound next week, with market participants closely watching the 1,500-point support level. It remains to be confirmed whether the market will stabilize at this support level or if further downward pressure will persist as the tech sector continues to face scrutiny regarding AI expenditure.
