Summary · why it matters
Three brokerages expect the Thai stock market to drift lower this afternoon. Asia Plus Securities says the SET Index could correct to support at 1,560–1,595 points, pressured by a new round of trade tariffs as the US prepares to use Section 301 to impose import duties of 10–12.5 percent on more than 60 countries, replacing the global 10 percent tariff under Section 122 that expires this Friday. China, the EU, India, and several ASEAN nations are among those likely to be affected. For Thailand, the base case assumes tariffs of 15–20 percent and a best case of 10–15 percent, limiting the downside. The first support is at 1,627 points; if that holds, the pullback would be only halfway, but the index should fall all the way to 1,560–1,595 points. The brokerage recommends buying on weakness in AAV, AEONTS, AWC, BAM, BBL, BCH, BGRIM, CPALL, ERW, and MTC. ASL Securities notes that the morning session closed lower on selling in bank stocks after second-quarter 2025 earnings were fully reported, dragging the index down by more than 6.5 points, along with selling in large caps ADVANC and GULF on partial profit-taking. It sees fund flows starting to rotate back into foreign technology stocks, while some buying has emerged in domestic electronic components. It sets intraday support at 1,638 and 1,628 points, with resistance at 1,650 and 1,658 points. Globlex Securities says the index is consolidating on selling in banking, construction, ICT, and energy sectors. This afternoon the focus is on building a base above 1,635 points to avoid damaging the rebound structure. The index is expected to fluctuate in a range of 1,635–1,650 points. The morning session closed at midday at 1,640.85 points, down 12.12 points or 0.73 percent, with turnover of 65.905 billion baht.
