Market Roundup 15 September 2025

Thailand’s SET Index closed at 1,299.78 points, increased 6.16 points or 0.48% with a trading value of THB 35.28 billion. The analyst stated that the Thai market traded sideways within a limited range, challenging the resistance level of 1,300 points and returning to trading at the forward P/E ratio of 14x, the second highest in the region.

However, the lack of short-term supporting factors has pushed the index back to the closed point.

Meanwhile, investors are closely monitoring the FOMC meeting, which is expected to cut interest rates, as well as monitoring the Federal Reserve governor’s speech.
