I. VIETNAM STOCK MARKET WEEK 25-29/08/2025
Trading: The main indices remained in the green during the trading session on August 29th. The VN-Index closed just above the reference level at 1,682.21 points; the HNX-Index increased by 1.21% to reach 279.98 points. For the whole week, the VN-Index gained a total of 36.74 points (+2.23%), while the HNX-Index added 7.5 points (+2.75%).
The Vietnamese stock market experienced another volatile week. The sharp decline on Monday did not deter the VN-Index, as it quickly rebounded in the following sessions, despite the pressure of fluctuations near the peak and weak liquidity before the National Day holiday. Sector rotation continued, but the large-cap stocks took turns to support the index, helping it maintain its upward momentum. The VN-Index ended the last trading session of August at 1,682.21 points, a 2.23% increase compared to the previous week.
In terms of impact, VPB made the most positive contribution on Friday, adding nearly 2 points to the VN-Index. This was followed by HDB, MBB, and HPG, which together contributed an additional 2.3 points. On the other hand, VIC and FPT exerted the most significant downward pressure, taking away 1.6 points and 1.1 points, respectively.
The sectors showed a clear differentiation. On the positive side, financials stood out with widespread gains, especially in banking and securities stocks such as MBB (+2.02%), HDB (+2.92%), VPB (+2.94%), STB (+1.46%), VIB (+2.03%), SHB (+2.17%), VCI (+4.32%), SHS (+6.96%), and HCM (+3.19%). Additionally, VND, ORS, AGR, TCI, and DSE reached the maximum daily limit.
In contrast, the information technology sector lagged with a sharp decline of 2.68%, mainly due to selling pressure in FPT (-2.78%), CMG (-1.47%), ELC (-1.59%), VEC (-7.83%), POT (-1.38%), and HPT (-2.68%).
The utilities and media sectors also witnessed adjustments of over 1% as several large-cap stocks in these sectors declined notably, including GAS (-1.69%), REE (-0.61%), GEG (-1.27%), DNH (-14.61%), VGI (-1.34%), and VNZ (-5.06%).
Foreign investors offloaded a significant amount, with a total net sell value of over 11.2 trillion VND on both exchanges during the week. They net sold nearly 11.3 trillion VND on the HOSE but net bought slightly over 13 billion VND on the HNX.

Stocks with notable performance this week: ORS
ORS increased by 28.91%: ORS concluded a brilliant trading week with five consecutive gaining sessions. The stock price rose above the Upper Band of the Bollinger Bands, accompanied by a trading volume that was higher than the 20-session average, indicating a very optimistic investor sentiment.
The Stochastic Oscillator and MACD continued to rise after generating buy signals, reinforcing the positive short-term outlook.
Stocks with significant declines this week: HAR
HAR decreased by 12.52%: HAR failed to surpass the previous peak from August 2022 (around 5,800-6,300) and is currently testing the Middle Band of the Bollinger Bands. This level will act as a crucial support in determining the short-term trend of the stock.
The trading volume has significantly dropped in recent sessions, reflecting investors’ cautious attitude. Meanwhile, the Stochastic Oscillator remains weak after giving a sell signal and exiting the overbought zone, warning of potential further corrections if the situation does not improve in the upcoming sessions.
