Trading Session Overview
At midday on August 20, 2026, the Vietnamese stock market continued to show a divided picture, with VNINDEX at 1,731.8 points, up 0.3%, and liquidity reaching 172.8 million shares. Upward momentum remains, but the narrow range suggests cash flow is selective rather than broadly spreading.
On the index front, HNXINDEX slipped 0.6% to 278.3 points, while UPCOMINDEX rose 0.5% to 127.5 points. Overall, the market has not formed a clear consensus trend, instead leaning toward rotation across different stock groups.
Notable Stock Groups
On HOSE, the top gainers included PIT, up 7.0%, ACC, up 6.9%, and PMG, up 5.2%. These stocks are leading the short-term upward move, although market breadth has not yet truly broadened.
On the other side, the steepest decliners were VDP, down 6.9%, HAS, down 6.9%, and DAT, down 6.9%. The correction in this group shows that divergence risk remained clearly present during the session.
| Ticker | Change | Liquidity |
|---|---|---|
| PIT | +7.0% | 35.6 thousand shares |
| ACC | +6.9% | 222.7 thousand shares |
| PMG | +5.2% | 200 shares |
| VDP | -6.9% | 2.3 thousand shares |
| HAS | -6.9% | 100 shares |
| DAT | -6.9% | 3.1 thousand shares |
Sector Analysis
Liquidity was concentrated heavily in VIX, with 13.6 million shares, followed by SHB at 5.4 million and HPG at 5.1 million shares. This suggests cash flow still favors stocks capable of absorbing large volumes, with the financial and steel sectors continuing to play a notable role.
Among stocks showing favorable technical signals, CLW scored 72.3 composite points, BSR scored 71.1 points, and PVP scored 69.5 points. These signals indicate that some stocks still have room to sustain a rebound if liquidity improves further.
- HNX stood out with DTG up 10.0% and ICG up 9.7%, while PJC fell 9.9% and PTX fell 9.7%.
- UPCOM recorded VET up 15.0% and NDC up 15.0%, but also faced heavy selling pressure in FTI, down 32.4%, and YBC, down 14.9%.
- Overall, the gap between advancing and declining stocks remains wide, reflecting the cautious sentiment of investors.
Short-Term Outlook
In the short term, the 1,730-point zone of VNINDEX serves as an important equilibrium level. If liquidity holds and the leading groups spread gains more effectively, the index may sustain its positive momentum; conversely, deeper divergence and correction pressure in weaker stocks could lead to higher volatility.
With HNXINDEX and UPCOMINDEX, the mixed performance suggests that cash flow is still testing various groups rather than settling on a unified direction. Investors should monitor how widely liquidity spreads over the remainder of the session to assess the likelihood that the current trend can hold.
