Retail investors net bought 3.50 trillion dong in the week as Vietnam's stock market is officially upgraded

The VN-Index closed week 15/2026 at 1,750.00 points, up 65.96 points (+3.92%), extending a third consecutive weekly rebound after a prior dip. Liquidity improved following a four-week decline, indicating demand has strengthened, though participation remains cautious.

Trading value and liquidity across exchanges

On the Ho Chi Minh City Stock Exchange (HOSE), the average value of matched trades reached 20,776 billion dong per session, up 1.69% week-on-week. However, it remained well below the five-week average (down 21.72%), suggesting capital is returning but not yet broadly strong.

Across all three exchanges, total average daily turnover was 26,523 billion dong, while matched trades totaled 22,646 billion dong. Matched trades were up 0.63% week-on-week but down 23.13% versus the five-week average.

Sector rotation and market cap allocation

In week 15/2026, money flow continued to shift toward pillars such as Banking, Real Estate, Securities, and Steel, while retreating in Retail, Chemicals, Oil & Gas, and Equipment & Oil & Gas services. Sectoral money flow showed clearer leadership in leading groups, with price movements broadly positive.

Banking led with higher weights and rising prices. Real Estate maintained momentum supported by large-cap and mid-cap stocks, while Securities and Steel also improved in both money flow and price. Meanwhile, money continued to exit Energy and some previously rallying sectors, reflecting rotation toward areas with clearer leadership.

Index breadth: VN30 and mid-cap strength

Sector allocation by market cap remained focused on blue chips. VN30 weighting rose to 51.4% (from 50.6% in week 14), while VN MID and VNSML were around 40.2% and 4.9%, respectively.

Price performance was broadly higher: VN30 was up 4.94%, VN MID up 4.70%, and VNSML up 1.33%. Liquidity improved for VN30 (+3.3%, about +337.7 billion) and VN MID (+1.4%, +112.1 billion), while VNSML weakened slightly (-0.3%, -3.2 billion).

Overall, the pattern suggests capital is returning selectively, concentrating on large-cap stocks and some mid-caps, while small-cap participation remains limited.
