Thai Stock Market Falls 26.36 Points as Delta Drags Index
Thailand's stock market fell 1.62% to 1,598.11 points on July 30, dragged down by a 7.37% plunge in Delta, the country's most-traded stock, amid global semiconductor weakness and Middle East tensions.
Trinity Securities reported that the Thai stock market on July 30, 2025 closed at 1,598.11 points, down 26.36 points or 1.62% from the previous day, trading between 1,587.29 and 1,616.06 points with a total trading value of 112,047.42 billion baht. The market faced significant pressure from Delta, which fell 7.37% and is the highest trading value stock on the market, with major impact on the index. This aligns with selling pressure in foreign markets where semiconductor and technology stocks face concerns over earnings and valuations. Middle East tensions also pushed global oil prices higher, which while benefiting upstream energy stocks, increased concerns about inflation and business costs, particularly for transport, petrochemical, and energy-intensive industries. Foreign investors sold a net 1,739.41 million baht, domestic institutions sold a net 1,191.43 million baht, and securities accounts sold a net 3,424.73 million baht, while domestic retail investors bought a net 6,355.57 million baht. Top traded stocks included Delta (down 7.37% to 264 baht, 11,119.74 million baht traded), True (up 5.04% to 14.60 baht, 8,388.14 million baht traded), KBANK (flat at 242 baht, 5,884.10 million baht traded), KTB (down 1.72% to 42.75 baht), and Gulf (up 0.77% to 65.75 baht). Key market drivers included Delta's sharp decline weighing heavily on the index, negative sentiment in chip and AI stocks reflecting foreign semiconductor weakness, Middle East tensions raising oil prices and inflation concerns, and net selling by three major investor groups offset entirely by retail buying.
