Trading Session Overview
The 18/05/2026 session showed a clearly divided market, with VNINDEX closing at 1,927.9 points, up 0.3%. Cash flow remained active but selective, concentrating on a few large-cap stocks and individual sector groups rather than spreading evenly.
On the Hanoi exchange, HNXINDEX rose 0.7% to 259.3 points, while UPCOMINDEX fell 0.6% to 125.9 points. This movement suggests that the short-term recovery trend still holds, but market breadth continues to diverge across market-cap segments and trading exchanges.
Liquidity and Cash Flow Dynamics
Trading liquidity on HOSE was concentrated in VIX with 44.2 million shares, SHB with 44.0 million shares, and HPG with 27.5 million shares. This concentration indicates that cash flow still favors stocks with broad coverage and high liquidity, amid investors' continued cautious sentiment.
| Ticker | Value | Movement |
|---|---|---|
| VIX | 44.2M | Leading liquidity on HOSE |
| SHB | 44.0M | Very high liquidity |
| HPG | 27.5M | Cash flow-driven group |
Notable Stock Groups
On the upside, the top gainers on HOSE were VAF (+9.6%), PLX (+7.0%), and BVH (+6.9%). Conversely, the steepest decliners were BTT (-6.7%), AAM (-6.6%), and ADG (-6.5%).
Large price swings across many stocks show that the market is moving on individual narratives rather than rising or falling together across the board. This is typical of a short-term rotation, in which investors focus on stocks with positive technical signals and strong cash flow.
| Group | Ticker | Change |
|---|---|---|
| Strong gainers | VAF | +9.6% |
| Strong gainers | PLX | +7.0% |
| Strong gainers | BVH | +6.9% |
| Strong decliners | BTT | -6.7% |
| Strong decliners | AAM | -6.6% |
| Strong decliners | ADG | -6.5% |
Sector Analysis
Financials and financial services remained a highlight, with many stocks showing high liquidity and positive technical signals. In industrials, PVT rose 5.2% and VTP rose 4.8%, while in oil and gas, PLX and BSR posted strong breakouts.
Conversely, some defensive and consumer groups continued to face divergent pressure. This reflects a lack of consensus in cash flow, so the potential for further gains depends more heavily on sector-leading stocks.
Notable Technical Signals
Among the standout technical signals, PVT and GSP both reached a composite score of 75.5, followed by HCM at 74.6. These signals suggest that the technical condition of several stocks still leans positive, although short-term indicators warrant close monitoring given the high degree of divergence.
- PVT: 75.5 composite points, with positive MACD and EMA signals.
- GSP: 75.5 composite points, with a similar technical trend.
- HCM: 74.6 composite points, maintaining a relatively solid price base.
Outlook and Risks
In the short term, the current point zone of VNINDEX still shows an unbroken recovery trend, but volatility pressure may increase as cash flow prioritizes selective stock picking over broad-based buying. The 1,920-point zone remains an important level to watch, while a more sustainable upward move will require stronger consensus among leading stocks.
In the current context, investors should pay attention to stocks with good liquidity and technical signals, while monitoring the market's reaction around nearby resistance levels. The data suggests opportunities still exist, but divergence will continue to be the defining feature of the coming session.
