Vietnam’s VN-Index Breaks 1,850 Barrier on Foreign Return
On September 4, 2026, the VN-Index closed up 25.36 points at 1,853.08, breaking through the psychological resistance of 1,850. This rally was fueled by a reversal in foreign investor sentiment, which shifted to net buying approximately 116 billion VND across the market after previous selling pressure. The surge was primarily driven by real estate blue chips, with VIC (Vingroup) and VHM (Vinhomes) attracting significant capital inflows
Indonesia’s IHSG Jumps 1% on Banking Sector Frenzy
The Jakarta Composite Index (IHSG/JCI) rallied 1.09% to close at 6,667 on September 3, 2026, marking a strong start to the week. Foreign investors executed a significant net buy of Rp1.07 trillion, heavily concentrating their purchases in large-cap banking stocks such as Bank Mandiri (BMRI) and Bank Central Asia (BBCA). This inflow contrasted sharply with the previous week's net sell of Rp1.31 trillion, signaling a renewed confidence in Indonesia's financial sector
Thailand’s SET Index Volatility Amid Global Uncertainty
Thailand’s SET Index experienced choppy trading during the first week of September. On September 2, the index closed down 13.61 points at 1,575.07 as investors reduced exposure due to Middle East tensions and US interest rate concerns. However, it rebounded slightly on September 3, closing up 1.85 points at 1,576.92, supported by a strengthening Thai baht and easing bond yields. By September 4, the SET gained 18.66 points (+1.18%) to close at 1,595.58, driven by buying from funds, property developers, and foreign investors who bought a net 1.36 billion THB
Philippines PSEi Sees Continued Foreign Outflows
The Philippine Stock Exchange Index (PSEi) closed at 6,069.42 on September 3, 2026, up 16.19 points (+0.27%). Despite the modest gain, foreign investors continued to be net sellers, offloading ₱342.25 million worth of shares. The market turnover remained moderate at ₱5.23 billion, reflecting a cautious sentiment among both local and international participants
Local view
In Vietnam, local media highlighted the significance of the foreign return to the market. CafeF noted that the "reversal" in foreign flows was concentrated in specific high-cap stocks like VIC and VHM, suggesting that while the broader market remains cautious, institutional money is picking specific winners. Thời báo Tài chính Việt Nam reported that despite the index's strength, liquidity remained somewhat low at 16.7 trillion VND, indicating that the rally was driven by price appreciation in large caps rather than broad-based participation
In Indonesia, CNBC Indonesia pointed out that while the overall market saw foreign selling earlier in the week, the strategic accumulation of banking stocks by foreigners was the key driver for the IHSG's late-week recovery. Analysts suggest this indicates a preference for defensive, yield-bearing assets amidst global volatility
