Selling pressure from very early on in a wide area in today's session - March 6th has caused the market to fall deeply, and there have even been retests of 1,780 point support. Although touching the above support twice, the VN-Index both showed signs of rebounding, even at times returning to reference. However, the lack of support pillars and investors losing patience when the developments in the Middle East are unclear will occur in the last days of the week has caused low supply pressure to increase sharply towards the end of the session.
The focus of the market in the week was the oil and gas stock group with expectations of benefiting from Middle East tensions. However, after a series of breakthroughs, this stock group was profit-taken and fell into a sell-off situation. At the closing session, only BSR and PVT maintained strong growth momentum; the remaining codes mostly decreased sharply such as: GAS (down 6.3%), PGM (down 7%), PLX (down 4.2%), PET (down 2.5%), PGD (down 2%).
The strongest decrease was in the securities group with a series of codes falling to the floor and near the floor. However, the most negative impact on the market was VIC when it contributed to causing the index to decrease by 13 points.
The fact that the pillar codes of important industry groups were submerged in red caused VN Index to almost "freefall". At the end of the session on March 6, VN Index decreased by 40.67 points, equivalent to 2.25%, to 1,7677.8 points. Red color covered the HoSE board with 237 decliners, compared to 88 gainers.
HoSE liquidity continued to decline but still maintained above the milestone of 1 billion shares and 30,000 billion VND. Specifically, there were more than 1 billion shares matched orders, equivalent to a transaction value of 32,300 billion VND.
Although foreign investors maintained selling pressure, the net selling value was no longer as strong as the previous session. In today's session, foreign investors only net sold more than 1,300 billion VND on the HoSE exchange. Leading the list of strongest net selling in the market is still FPT with 578 billion VND.
Today's trading session also marked the strongest plunge since December 2025. Overall for the week, the market experienced 4 sessions of decline, while only slightly increasing in one session, causing the index to lose a total of 112 points.
Rong Viet Securities Company (VDSC) commented that the event of the US and Israel attacking Iran is considered a "black swan" causing fluctuations for the market in the first 1-2 weeks of March. Accordingly, VDSC experts predict that the market will be difficult in the first half of the month. If the information is clearer, the diễn biến will improve in the second half of the month. The positive point is that after 2 years of challenges, Vietnamese investors have become more professional and calm, no longer overreacting to international events.
In terms of domestic macroeconomics, the PMI index has expanded above 50 points for 8 consecutive months, showing that production activities are recovering well. Public investment and tourism continue to be the main driving force for the domestic macroeconomy.
In a negative scenario, if Iran closes the strait, rising commodity prices will lead to inflation returning, causing the Fed not only not to reduce interest rates but may also raise interest rates, negatively impacting the exchange rate and the Vietnamese economy. Investors should monitor and be cautious in the next 4-5 months, maintaining a high proportion of cash.
Investors also believe that if the war lasts for more than 1 month, it will break the supply chain, increase freight rates and directly affect the operational efficiency of Vietnamese import-export enterprises. Therefore, it is recommended that investors do not use leverage (margin) during difficult times to avoid strong fluctuations. Maintain a cash ratio of about 10-20% to prepare for unexpected risks.
