Market in Red, VN-Index Drops Over 42 Points

On August 22, 2025, the Vietnamese stock market closed a highly volatile session as the VN-Index plunged 42.57 points, ending at 1,645.47 points. Liquidity on HoSE reached nearly VND 62.14 trillion, indicating strong capital flows but also reflecting heightened selling pressure and risk aversion.

The main drag came from large-cap stocks in the VN30 basket, with three notable names hitting floor prices: VPB (VPBank), SHB (Saigon – Hanoi Bank), and GVR (Vietnam Rubber Group).

Three Major Losers of the Session

• VPB: After five consecutive gaining sessions, including two limit-up sessions driven by the IPO plan of subsidiary VPBankS, the stock suddenly plunged 6.34% to VND 36,200/share, surprising many investors.

• SHB: Fell more than 5.6%, marking a sharp correction following its short-term rally.

• GVR: Also suffered heavy sell-off pressure, hitting the floor price and reflecting strong profit-taking activity.

On the positive side, several tickers such as BID, VIB, VCB, and DGC managed to remain in the green, becoming rare bright spots in an otherwise gloomy session.

Analytical Perspective: Why Did the Market “Reverse”?

The Aftermath of FOMO Waves

The sharp drop in VPB following consecutive limit-up sessions is a classic case of FOMO (Fear of Missing Out) in stock trading. Initially, the IPO news of VPBankS served as a powerful catalyst, triggering strong buying demand. Many investors, without thoroughly analyzing valuation or long-term prospects, rushed to buy simply out of fear of missing out. This quickly inflated prices beyond sustainable levels.
However, once the IPO story was fully priced in, upside momentum faded. Demand
weakened while profit-taking pressure surged, pushing the stock straight to the floor. This illustrates how FOMO-driven rallies can create short-term gains but also set traps for latecomers when sentiment shifts.

A Healthy Technical Correction

While a 42-point drop in a single session is significant and unsettling, it can also be viewed as a healthy technical correction. No market can rise indefinitely without pauses, and corrections help cool down excessive optimism, flush out speculative money, and pave the way for more sustainable growth.
In recent weeks, VN-Index has reached new highs on strong inflows, particularly into banking, real estate, and brokerage stocks. When large-cap valuations run ahead of fundamentals, profit-taking is inevitable. Thus, this correction is better seen as a cooling-off phase to restore balance rather than a sign of long-term weakness.

Fragile Investor Sentiment

Liquidity during the session stood at over VND 62 trillion, showing that capital remained in the market. Yet, the immediate wave of selling highlighted the fragile sentiment of investors. Most flows were short-term oriented, chasing momentum instead of building long-term positions.
This reflects a structural characteristic of the Vietnamese market: retail investors dominate trading, while institutional and long-term capital remain underrepresented. As a result, even small negative signals can trigger large-scale sell-offs due to herd behavior.

Influence of Macro Factors and Foreign Capital Flows

Beyond domestic triggers, the market was also influenced by global macro conditions. Elevated international interest rates, a stronger USD, and ongoing geopolitical uncertainties have made foreign investors more cautious. On August 22, foreign funds recorded net selling, adding to the downward pressure on large-cap stocks.
This highlights the importance of foreign capital as a key variable in VN-Index movements. Sustained net outflows could pose further short-term challenges, even if domestic fundamentals remain supportive.

Lessons for Investors

• Avoid chasing short-term rallies: Consecutive limit-up sessions often come with heightened risks of sharp pullbacks.

• Focus on fundamentals: IPO announcements or macro news are short-term catalysts; the intrinsic value of companies determines long-term performance.

• Stay disciplined and rational: The stock market always moves in cycles. A calm, long-term perspective helps investors avoid panic selling in volatile sessions.

A Warning, Not a Red Flag

The August 22 session served as a reminder that the market cannot rise in a straight line. While the sharp drop alarmed many, the long-term outlook for Vietnam’s stock market remains intact, supported by a resilient economy and continued interest from foreign investors.

The key takeaway is not to chase speculative waves but to selectively invest in fundamentally strong companies for long-term gains.
