VN-Index closed October in red, blue-chip stocks plummeted

The Vietnamese stock market ended the trading session on October 31 with a strong "misstep" in the afternoon, when the restructuring effect of domestic ETFs caused widespread selling pressure on large-cap stocks. Negative sentiment spread rapidly, creating a volatile trading session on the last day of October.

Cash flow cautiously withdrew, the market lost the 1,640 point mark in the red color at the end of the month

VN-Index closed down 1.79%, equivalent to 29.92 points, falling back to over 1,639 points. This was the sharpest decline in over a week, extinguishing the index's recovery efforts in previous sessions. Notably, the decline occurred simultaneously on the main pillars, especially stocks in the Vin ecosystem and the banking group.

VIC continued to be the main driving force causing the VN-Index to plummet, losing 6.42%, thereby taking away 10.7 points from the index. VHM decreased 4.62%, equivalent to -4.2 points. In addition, large codes such as VCB (-1.65%), BID (-1.32%), TCB (-1.68%), VPB (-1.71%), MBB (-1.46%) were all in a state of deep correction. This simultaneous decline created great pressure on the market.

In the VN30 group, 21/30 stocks decreased in price, of which 19 stocks decreased by more than 1% and 9 stocks decreased by more than 2%. The VN30-Index accordingly evaporated by 2.07%, clearly reflecting the impact of portfolio restructuring activities from ETF funds following VN30 and VNFINLEAD. For example, MBB was on the list of selling more than 5.8 million shares, while TCB also sold more than 5 million units.

On the other hand,FPT is a rare stock that maintains green (+1.17%) and also contributes large liquidity, but FPT's own pulling force is not enough to offset the widespread selling wave in the pillar group.

Liquidity across the HoSE floor increased sharply with 837 million shares matched, equivalent to VND27,185 billion. This is a signal showing increased selling pressure, especially in the context of ETF restructuring. However, the total value of matched orders across the three floors only reached nearly VND29,612 billion, still far below the average of VND47,557 billion/day of the previous week.

This shows that bottom-fishing cash flow is still cautious, investors still prioritize keeping cash in the face of the risk of the market continuing to adjust.

Market breadth is tilted towards the selling side: 190 stocks decreased compared to 127 stocks increased on HoSE. Up to 115 stocks decreased by more than 1%, reflecting the overall negative sentiment. Many speculative and mid-cap stocks also "plummeted": GEX continued to hit the floor for the second consecutive session, trading more than VND 1,253 billion; VIX decreased by 4.44% with liquidity of nearly VND 1,373 billion; CII (-1.43%), DXG (-4.48%), HCM (-1.06%), GMD (-3.4%) all traded more than VND 300 billion.

The fact that more than 62% of the transaction value fell into the group of stocks that fell sharply shows that the level of loss of investors in the session was quite large.

Foreign investors continued to maintain a net selling position on HoSE with a value of 461 billion VND, focusing on pillars: VIC, VHM, CTG, MBB, HPG were all sold more than 100 billion VND; VIX was a rare bright spot with a net buying of 107 billion VND.

Pressure from foreign capital flows makes it even more difficult for the market to maintain its recovery in the short term. After 4 sessions of trying but failing to conquer the psychological mark of 1,700 points, VN-Index fell straight to the 1,639 point area. According to current signals, the risk of falling back to the 1,600 point area is clearly increasing.

The market has passed the explosive period of Q3/2025 business results information, while new supporting factors have not appeared. Investors have reason to wait for more attractive prices in the next corrections.

With the sharp decline of the pillar group and the narrowing cash flow, the market is likely to enter a period of struggle, accumulating the price level. Short-term speculative opportunities only appear in some stocks with their own stories, while a defensive strategy, prioritizing risk management is recommended in the current context.

October ended with a red color, leaving a lot of pressure on the market's performance in the following weeks. Investors need to closely monitor the actions of foreign capital flows, ETF developments and the endurance of blue-chips, which are the keys to the big trend of VN-Index in the coming time.
