SET Index Faces Headwinds as Support Levels Tested and Rebound Hinges on Election Optimism

Mr. Suchet Suktae, Deputy Managing Director, Media Marketing Department of ASL Securities, during the “Kaohoon” program on December 30, 2025, expects today’s support and resistance levels for the Stock Exchange of Thailand (SET) Index to be 1,250/1,243 points and 1,265/1,285 points, respectively.

ASL Securities has also estimated support and resistance levels for specific stocks. The details are as follows:

  • PTT Exploration and Production PCL (SET: PTTEP): THB 110 – 109 per share and THB 112.50/115.50 per share for its support and resistance levels.
  • CP All PCL (SET: CPALL): THB 43 and THB 44.50/46/47.
  • Bangchak Corporation PCL (SET: BCP): THB 25.50 – 25 and THB 27/28.25.
  • Electricity Generating PCL (SET: EGCO): THB 110 – 109 and THB 113/118/122.
  • S Hotels and Resorts PCL (SET: SHR): THB 1.72 – 1.70 and THB 1.77/1.85.

Mr. Suchet noted that the SET Index is facing challenges as it is being weighed down by the weakness in Asian markets and the U.S. Dow Jones Industrial Average. If the SET Index falls below today’s support level, it will generate negative sentiment and make it difficult for the index to recover.

Nonetheless, Mr. Suchet forecasted that the SET Index will rebound this January due to the election rally. However, he cautioned that 2026 could remain a challenging year for Thai investors, but noted greater stability could emerge in 2027 as government formation would have been completed by then.

At present, Mr. Suchet cautioned against technology and ICT stocks, particularly high-growth names, due to volatility in the AI sector that has weighed on stock market indices in both Asia and the United States. He also warned investors to exercise caution as the SEC has recently taken legal action against stock price manipulation.
