The rise in the aforementioned stocks is attributed to increased inflows from foreign investors. Data from the Stock Exchange of Thailand as of July 29, 2025, indicated continuous buying activities from overseas investors through Non-Voting Depository Receipt (NVDR).
The focus remains on big-cap stocks with strong fundamentals and a positive outlook for a recovery in earnings in the second half of 2025, reflecting robust foreign confidence in Thailand’s economic trajectory and capital market prospects.
Among the top purchased shares in total value are PTTEP, which recorded a total value of THB 788.34 million, and PTT, with total value of THB 585.71 million.
Analysts note that, aside from the strategic accumulation of energy stocks, sentiment has also benefited from progress in trade negotiations between Thailand and the United States, as well as the recently announced ceasefire between Thailand and Cambodia.
Koraphat Vorachet, Deputy Managing Director and Division Head of Research at Krungsri Securities (KSS), summarized four key drivers of the Thai stock market:
1) Easing global economic tension and improved international stability, bolstered by trade agreements between the U.S. and Europe, which include a 15% tariff on most European goods in exchange for gas imports and investment in the U.S. over the next 3–5 years.
Additionally, the U.S. further extended the tariff truce with China for another 90 days, and President Trump signaled a global baseline tariff ceiling of 15–20%, all increasing investor confidence.
2) Thailand–Cambodia ceasefire paved the way to the U.S. trade deals, as the de-escalation of disputes between the two nations is creating a more favorable climate for trade and diplomatic relations.
Krungsri Securities’ base case forecasts Thailand securing a 25% tariff framework, providing a “strategic upside” for the export sector and foreign direct investment.
3) Oil prices recovered by 2.36% as trade deals progressed. The energy sector, carrying a 10% market capitalization weight, is benefiting from a sustained uptrend in crude prices, fueling speculative buying in stocks like PTT, PTTEP, and TOP.
4) Delta Electronics (Thailand) Public Company Limited (SET: DELTA) reported lower-than-expected earnings, but the capital remains in the market. While DELTA’s profits fell short due to weakening margins, this unlocked potential rotation for capital to move toward other big-cap stocks.
Gains are likely across several sectors, with energy companies poised to benefit from rising oil prices and improved trade sentiment. The ‘China Plays’ stocks could attract investor interest as diplomatic relations between Washington and Beijing show signs of improvement.
The banking industry stands to gain from the upcoming Federal Reserve’s decision to potentially maintain interest rates. Meanwhile, ADVANC may see additional momentum as it approaches its interim dividend payout for the first half of 2025.
