– The positive sentiment from the strong recovery in the previous session boosted the market’s opening on August 27. The VN-Index quickly advanced to challenge the 1,695-point threshold within the first hour of trading. However, profit-taking pressure at higher levels persisted, narrowing the gains. Despite significant support from the large-cap ticker VCB, the upward momentum was insufficient to counter the net selling pressure from foreign investors. The VN-Index fluctuated around the 1,675-point level in the afternoon session and closed at 1,672.78 points, up slightly by 0.31% from the previous session.
– In terms of impact, VCB was the leading stock, contributing 9.4 points to the VN-Index. This was followed by FPT and BID, which added over 3.7 points combined. On the other hand, VIC was the most negative stock, causing the index to lose 3 points.
– The VN30-Index closed just below the reference level, settling at 1,848.55 points. The basket had a relatively balanced performance, with 14 gainers and 16 losers. Among the gainers, VCB stood out with a substantial increase, while FPT, SSI, and BID also recorded growth ranging from 2% to 5%. Conversely, LPB and TPB were the worst performers, declining by over 3%.
Sectors exhibited clear differentiation. Information Technology led the gains, driven mainly by the industry’s two largest stocks, FPT (+5%) and CMG (+2.27%).
The Financials sector witnessed several stocks surging, including VCB (hitting the ceiling price), BID (+2.39%), ACB (+1.1%), SSI (+2.68%), STB (+1.09%), VND (+3.48%), and VIX (+5.74%). However, red ticks also appeared intermittently, with notable mentions including TCB (-1.02%), LPB (-3.74%), VPB (-2.92%), VIB (-1.76%), TPB (-3.58%), and NAB (-3.05%).
On the flip side, Energy was the worst-performing sector, declining by 1.33%, mainly due to tickers such as BSR (-3.46%), OIL (-0.86%), VTO (-0.83%), PVC (-0.87%), CST (-1.33%), and PVB (-1.06%).
The VN-Index narrowed its gains towards the end of the session and formed a Long Upper Shadow candle. This pattern indicates persistent profit-taking pressure at the previous high of 1,680-1,693 points. Additionally, the Stochastic Oscillator indicator continued to weaken after generating a sell signal, suggesting that the index may face further volatility in the upcoming sessions.
