– The market extended its rally in the first session of the week. The VN-Index opened in the green and approached the 1,675-point mark within the first hour. Although the upward momentum slowed due to divergence among large-cap stocks, mid- and small-cap stocks maintained strong demand, helping the index hold steady after adjustments around the 1,670-point level. Late in the session, a strong comeback from leading stocks propelled the index higher. The VN-Index closed at 1,684.9 points, up 17.64 points from the previous session.
– In terms of influence, BID, CTG, and HVN were the most positive contributors, adding nearly 5 points to the VN-Index. Conversely, VHM had the most significant negative impact, reducing the index by nearly 1 point.

The short-term outlook for the index has turned more positive as the Stochastic Oscillator has given a buy signal. The upward momentum will be further supported if trading volume soon exceeds the 20-day average in the coming sessions.

– 17:10 September 15, 2025
September 16, 2025: Optimism Spreads Across the Warrant Market
At the close of trading on September 15, 2025, the market saw 147 stocks rise, 79 decline, and 33 remain unchanged. Foreign investors continued their net buying streak, accumulating a total of 1.09 million CW.
Vietstock Daily 17/09/2025: Market Shakes at the 1,700-Point Threshold
The VN-Index retreated after facing profit-taking pressure at its August 2025 peak and early September 2025 highs (around 1,690–1,711 points). Volatility near this resistance zone is likely to persist in the short term. Should selling pressure dominate, the short-term trendline support (approximately 1,635–1,650 points) will be critical for the index.
Vietstock Daily 19/09/2025: Market Volatility Persists – Can Stability Be Regained?
The VN-Index swiftly narrowed its decline and closed just above the Middle Bollinger Band. This indicates that the short-term trendline (ranging between 1,645 and 1,660 points) continues to effectively support the index. However, with trading volume showing no signs of improvement, expectations for a short-term breakout or surge remain low.
Vietstock Daily 18/09/2025: Cautious Sentiment Prevails?
The VN-Index persists in its corrective phase, with trading volumes remaining below the 20-day average for seven consecutive sessions, reflecting investors’ cautious sentiment. However, short-term risks appear manageable as the Stochastic Oscillator has generated a buy signal, and the short-term trendline (equivalent to the 1,635-1,650 point range) continues to provide robust support.

As the trading session closed on September 17, 2025, the market witnessed 68 stocks advancing, 159 declining, and 32 remaining unchanged. Foreign investors continued their net selling streak, offloading a total of 3.93 million CW units.
