Thai Stock Market Faces Limited Upside as Index Surge Sharply in Post Election

Mr. Weerawat Wirojphoka, Senior Director of FSS International Investment Advisory Securities (FSSIA), stated that the Stock Exchange of Thailand (SET) Index closed the morning session higher by 0.35%, or 4.86 points, at 1,405.75 points, as upside became increasingly limited near the 1,410-point level, triggering selling pressure.

Both the index and several stocks have entered an overbought state due to political clarity following the election, and expectations of positive sentiment regarding the stability of a strong government.

Meanwhile, the investment atmosphere abroad remains positive, buoyed by the continuous recovery of technology stocks, following heavy selling pressure last week. This has been a supportive factor for DELTA, but currently, the stock price is not increasing much further.

In the next period, focus will be on the formation of the new government as well as the disclosure of listed companies’ 4Q25 operating results. If these do not have a significant impact on 2026 projections, it is estimated they will help limit downside risk. As for external factors, attention remains on the release of U.S. economic data, including labor market figures and the Consumer Price Index (CPI).

Regarding calls for a new vote count in some areas, although these have not had a significant impact yet, if they become more widespread or escalate into a major movement requiring new vote counts in several areas, this could be a short-term pressure factor on the market.

The afternoon trend is expected to see the index fluctuate within the support range of 1,390-1,400 points and the resistance range of 1,410-1,420 points.
