In the trading session on January 20, the VN-Index at one point increased by nearly 20 points to 1,915 points and surpassed the old record, but the excitement did not last until the end of the session due to selling pressure in many large-cap stocks.
However, the excitement did not last long. Selling pressure from the VN30 basket spread, causing the VN-Index to reverse from increasing to decreasing.
At the close of the trading session on January 20, VN-Index decreased by 2.81 points to 1,893.78 points. Total trading volume reached more than 1.07 billion units, worth 37,051.6 billion VND. Block transactions contributed more than 90.5 million units, worth 4,080 billion VND.
The highlight in the session still came from bluechip stocks. In which, GVR, VNM and PLX stocks at times increased to the ceiling, but at the end of the session, in addition to PLX maintaining a high increase of +6.1% to 59,000 VND, the remaining two codes only increased by 2.6% and 4% to 39,000 VND and 73,400 VND respectively.
The following codes are LPB, BID and SAB with an increase of around 2%, the other banking group with SHB, VPB, VCB, HDB only increased slightly. In the opposite direction, Vingroup's stocks narrowed their decline, with VRE leading the decrease in the VN30 basket also only -2.6% down to 31,150 VND, while VIC, VHM only lost around 1%.
Foreign investors sent unfavorable signals when net selling up to 1,750 billion VND, the highest in the past month. Gemadept shipping company's shares faced strong selling pressure from foreign investors with a net withdrawal volume of more than 10 million units. VIX and HPG were ranked after being net sold by about 4 million and 3 million units respectively.
After a strong and decisive increase in the first trading sessions of 2026, the Vietnamese stock market in the past week has entered a clearer state of struggling. This development reflects a familiar rule of the market after acceleration phases: profit-taking pressure appears, but not panic but leans towards the process of "testing" supply and demand proactively.
VN-Index recorded interspersed adjustments, however, the positive point is that selling pressure tends to gradually weaken as the index retreats to the short-term support zone. Liquidity is maintained at a high level, averaging over 40,000 billion VND per session, showing that the market is shifting from a hot upward state to a accumulation phase, thereby creating a basis for further steps.
Investors believe that the market is likely to enter a phase of gradually narrowing the fluctuation range, accompanied by a decrease in liquidity. Some niche stock groups may continue to maintain their upward momentum, while large industry groups such as banking, securities, steel... will continue to strongly differentiate.
This period is suitable for a fast trading strategy and expects moderate performance. The potential support zone that investors can consider disbursing with a small proportion and vision over 3 months is around the 1,850 point mark. Experts recommend that investors limit chasing buys of stocks that have surpassed the old peak, instead prioritizing buying in accumulated base areas.
