I. VIETNAM STOCK MARKET FOR THE WEEK OF OCTOBER 27-31, 2025
Trading: Major indices universally declined in the October 31st session. The VN-Index retreated to 1,639.65 points, a sharp 1.79% drop from the previous session; the HNX-Index also adjusted by 0.42%, closing at 265.85 points. For the week, the VN-Index lost a total of 43.53 points (-2.59%), while the HNX-Index shed 1.43 points (-0.54%).
Vietnam’s stock market remained entrenched in a corrective trend during the final trading week of October. The early-week sharp decline was once again supported by the August 2025 lows, but the subsequent recovery was short-lived amid lackluster liquidity and weakened support from major stocks. Prolonged sideways sessions with significant volatility and alternating green and red hues vividly reflected strong polarization among stock groups. The VN-Index ended the week at 1,639.65 points, down over 43 points from the previous week.
In terms of impact, the 10 most negatively influential stocks collectively erased nearly 24 points from the VN-Index in the final session, with the heaviest pressure stemming from the duo VIC and VHM. Conversely, the contribution of the top 10 positive stocks managed to retain only 3.6 points for the index, underscoring the dominance of selling pressure.
Sector performance was markedly polarized. Real estate led the decline, plunging 4.22%. Selling pressure was widespread, not confined to the Vingroup family, with notable drops in CEO (-6.96%), DXG (-4.48%), PDR (-3.63%), DIG (-3.06%), KBC (-1.41%), TCH (-2.04%), and DXS (-5.41%), among others.
Additionally, financial and industrial sectors weighed heavily on the index, both recording declines exceeding 1%. Numerous stocks tumbled with significant liquidity, including VIX (-4.44%), HDB (-4.19%), SHB (-2.66%), STB (-2.46%), EIB (-2.21%); VJC (-4.35%), HAH (-2.07%), VSC (-5.5%), GMD (-3.4%), VTP (-3.19%), HVN (-4.24%), and GEX hitting the lower limit.
On the upside, energy emerged as a notable bright spot, with several stocks in the sector making impressive gains, including PVD hitting the upper limit, PVS (+1.55%), OIL (+2.83%), PVC (+3.88%), VTO (+2.52%), and PVB (+3.06%). Furthermore, media services and information technology sectors also shone in green, driven primarily by VGI (+7.3%), MFS (+1.4%), VTK (+1.69%); FPT (+1.17%), and CMG (+1.45%).
Foreign investors continued to net sell, with a total value exceeding VND 2.4 trillion across both exchanges last week. Specifically, foreign investors net sold VND 2 trillion on the HOSE and over VND 363 billion on the HNX.
