Thai Stock Exchange Set to Open Lower After Four-Session Rally

Thailand's SET Index is expected to open lower on September 23, 2026, following four consecutive sessions of gains totaling more than 40 points, or 2.7 percent. The index now sits just below the 1,605-point plateau. The retreat signals potential profit-taking after the recent rally, though no specific catalyst for the downside open was cited in early trading indications. Market participants will watch whether the index can hold above the 1,600-point level or extend losses through the session.
