The total trading value of the entire market reached more than 30 trillion VND, equivalent to about 988 million shares, lower than the average of the last 20 sessions. Of which, foreign investors continued to net sell 527.11 billion VND, focusing on the banking and real estate groups.

Market breadth was heavily tilted towards sellers with 414 stocks falling, while only 45 stocks rose and 21 stocks remained unchanged. Red covered almost the entire VN30 group, causing the index to lose 39.82 points (-2.07%) to 1,885.36 points.

The strongest selling pressure came from the large-cap group (VN30), especially the trio VIC (-6.42%), VHM (-4.62%) and GEX (-6.97%), taking away nearly 8.3 points from the VN-Index. Banking codes such as VPB (-1.71%), HDB (-4.19%), TCB (-1.68%), MBB (-1.46%) also traded negatively.

Meanwhile, some large stocks maintained green color such asACB (+1.59%), FPT (+1.17%), MSN (+0.38%), GAS (+1.09%), contributing to limiting the index's fall.

The real estate and finance groups recorded the sharpest declines of the day, -4.22% and -1.53% respectively, when many large codes simultaneously adjusted: VRE (-4.83%), DXG (-4.83%), CEO (-6.96%), VIX (-4.44%),SHB (-2.66%), SSI (-1.58%).

On the contrary, the insurance group (+0.99%), media - entertainment (+0.8%), food and beverage (+0.37%), and pharmaceuticals (+0.93%) were rare bright spots when recording the return of defensive cash flow.

During the day, the VN-Index continuously fluctuated and fell sharply right from the beginning of the morning session, then recovered slightly in the early afternoon session but quickly lost momentum towards the end of the session, closing at the lowest level of the day.

According to the trading chart, the index fluctuated around 1,650 points in the morning, then at times increased to nearly 1,665 points, but strong selling pressure on the VN30 group caused the index to fall straight to 1,640 points before closing the session.

The market is struggling, an attractive pricing zone is forming.

According to securities companies, the narrowing fluctuation margin reflects investors' cautious sentiment, especially when the market enters a short-term accumulation phase with low liquidity and increased defensive sentiment.

Hardware and equipment stocks (-5.45%), real estate (-4.22%) and credit institutions (-1.58%) were under the greatest selling pressure, while defensive groups such as insurance, pharmaceuticals, utilities and food attracted slight buying pressure.

According to ASEAN Securities Company (ASEANSC), the shaking trend may continue in the short term when the VN-Index is likely to return to test the support zone around 1,620 points, corresponding to the accumulation base formed since September 2025.

Saigon - Hanoi Securities Company (SHS) commented that the market is in an accumulation phase with a narrow range, fluctuating between the support zone of 1,620 points and the resistance zone of 1,700 - 1,710 points. Although demand at low prices has shown signs of improvement, selling pressure at high prices is still quite strong, especially in stocks that have increased rapidly in recent times.

From a more optimistic perspective, Yuanta Vietnam Securities Company (YSVN) believes that the VN-Index may soon recover in the coming sessions, with a resistance level of nearly 1,721 points. However, cash flow still tends to be differentiated, liquidity will generally remain at a low level due to investors' cautious psychology.

Notably, Tien Phong Securities Company (TPS) considers the 1,600 - 1,620 point area as an important "psychological cushion" for the medium and long-term uptrend, because this area has seen strong bottom-fishing buying power many times, demonstrating investors' acceptance of the current valuation level.

Meanwhile, Vikki Digital Bank Securities Company (VikkiBankS) believes that the market is clearly struggling, as the ADX technical indicator fluctuates in the 20-25 range, reflecting a sideways state with alternating increases and decreases. VikkiBankS assesses that short-term corrections can become opportunities for investors to select stocks with good fundamentals and reasonable valuations, in order to anticipate the new growth cycle of the market.

However, with the prospect after the market upgrade, experts expect that in the medium and long term, the market will remain positive thanks to three main drivers. Specifically, FTSE Russell has included Vietnam in the list of upgrades from "Frontier" to "Secondary Emerging", expected to take effect in September 2026. The total IPO value is expected to reach 47.5 billion USD in the next 3 years, expanding the supply of quality stocks. Foreign investors are expected to return to strong disbursement from 2026, after the current period of net selling.

It is believed that the VN-Index could reach 1,800 points in 2026, before heading towards 2,000 points in the medium and long term, thanks to corporate profit growth of about 15% per year, led by three industry groups: materials, finance and retail.

However, the current valuation level is still considered attractive in the medium term. Securities companies recommend that investors maintain a reasonable proportion, prioritize stocks with good fundamentals that have not increased strongly, and monitor signals from the 1,620-point support zone, which is considered an important buffer zone for the upcoming uptrend.
