Market close 18/09: VN-Index edged lower, with cash flow still selective in high-liquidity stocks

Trading Session Overview

At the close of the 18/09/2026 session, VNINDEX ended at 1,815.7 points, down 0.4%, signaling a mild correction after a period of consolidation near the upper range. Liquidity on the HOSE remained concentrated in several large-cap stocks, such as SHB with 51.8 million shares, VPB with 49.1 million shares, VIX with 43.7 million shares, and SSI with 36.4 million shares.

Market breadth continued to diverge sharply. On the upside, several notable breakouts included TNC, BVB, and LDG, while the steepest decliners were HAS, GTA, and CMV. This price action shows that money flow remains highly selective and has not yet spread broadly across the market.

Notable Stock Groups

HOSE: Notable Gainers and Decliners

Among the high-liquidity names, SHB, VPB, VIX, and SSI attracted the most significant capital flows during the session. This group also best reflected the choppy trading conditions, with buyers and sellers repeatedly taking turns in control.

Sector Analysis

The real estate group on the HOSE showed mixed performance: NVL rose 2.4% and KDH rose 1.3%, while VHM fell 0.4% and DXG fell 1.9%. The banking sector remained the focal point of liquidity, with SHB, VPB, HDB, VCB, and TCB diverging from stock to stock.

In financial services, SSI, VIX, VCI, VND, and VCK all maintained active trading. The technology, oil and gas, and retail sectors generally showed less consensus, reflecting money flow's preference for highly liquid stocks and short-term stories of their own.

HNX and UPCOM Overview

On the HNX, HNXINDEX rose 0.5% to 275.3 points, suggesting that the short-term trend remains positive. Standouts included TKU and NVB, both up 9.4%, while VLA and BXH also broke out strongly.

On the UPCOM, UPCOMINDEX rose 0.2% to 126.4 points, but volatility was very large. Strong gainers such as DLD (up 38.8%), PMT (up 37.1%), and UCT (up 35.7%) indicate very high selectivity, while the risk of sharp swings is also considerably greater.

Technical Signals and Outlook

Among the positive technical signals, TVS, TLG, CLC, and BTT all maintained alignment between MACD and EMA, suggesting that a short-term rebound remains possible for certain individual stocks. However, the overall market backdrop is still one of sharp divergence, so volatility is likely to persist in the coming sessions.

The 1,815-point zone for VNINDEX remains a key level to watch closely. If liquidity holds in the leading stocks and breadth improves, the market could maintain its consolidation; conversely, profit-taking pressure at elevated price levels could drive short-term volatility higher.
