The SET fell 2.3% in September to 1,559.01 points as foreign investors net-sold 26,328 million baht, though they remain net buyers of 24,856 million baht for the first nine months of 2026. Pressure cited: flood concerns, high energy prices, inflation, and Fed-driven bond yields. For a small business this is market background, not a trigger to act. Only relevant if you hold listed shares or plan to raise capital via the stock market.
