Market overview before the 17/09 session
In the previous session, VNINDEX was roughly sideways around 1,810.11 points, down 1.04 points (-0.1%). The overall picture shows the market's movement still leaning toward divergence rather than a clear expansion of trend.
Meanwhile, HNXINDEX slipped to 273.22 points, down 0.91 points (-0.3%), while UPCOMINDEX rose 0.51 points (+0.4%) to 125.98 points. This divergence suggests that cash flow has not spread evenly across the exchanges.

Notable technical levels
The nearby support zone for VNINDEX lies at 1,800–1,805 points, while the 1,815–1,820 point area is short-term resistance to watch. If the index continues to narrow around this zone, the market will likely remain within a tight trading range during the morning session.
Among technical signals, several stocks with high composite scores and positive trends stand out, including TVS at 83.7, PIA at 73.7, and DGW at 72.8. These stocks show a price base and short-term momentum that are relatively more stable than the broader market.
| Symbol | Exchange | Price | Composite score | EMA trend | MACD trend |
|---|---|---|---|---|---|
| TVS | HOSE | 14,350 | 83.7 | uptrend | uptrend |
| PIA | HNX | 29,300 | 73.7 | uptrend | uptrend |
| DGW | HOSE | 44,700 | 72.8 | uptrend | uptrend |
Standout stocks
On HOSE, the strongest gainers were TDW (+7.0%), SSB (+6.9%), and DCL (+6.9%). On the opposite side, PNC, HAS, and STG each fell 6.9%.
HOSE liquidity continued to concentrate in a few large-cap stocks with strong trading activity, such as SHB with 34.7M, VIX with 24.8M, and VPB with 17.6M. This suggests cash flow remains selective rather than widespread.
| Group | Symbol | Change |
|---|---|---|
| Strong gainers | TDW | +7.0% |
| Strong gainers | SSB | +6.9% |
| Strong gainers | DCL | +6.9% |
| Strong decliners | PNC | -6.9% |
| Strong decliners | HAS | -6.9% |
| Strong decliners | STG | -6.9% |
HNX and UPCOM: a clearer divergence
On HNX, strong gainers included VNT (+9.9%) and SGH (+9.7%), while the standout liquidity belonged to PVS, CEO, and SHS. On UPCOM, the strongest gainers were HHG (+16.7%) and NBT (+15.0%).
This development reinforces the view that cash flow is still seeking out stocks with their own stories, rather than chasing a broad-based rally across the market.
| Exchange | Index | Notable stock | Change |
|---|---|---|---|
| HNX | 273.22 | VNT | +9.9% |
| HNX | 273.22 | SGH | +9.7% |
| UPCOM | 125.98 | HHG | +16.7% |
| UPCOM | 125.98 | NBT | +15.0% |
Outlook before the session
The most likely scenario for the morning session is a cautious market opening that continues to fluctuate within a narrow range. If VNINDEX holds the 1,800–1,805 point zone, market sentiment may stabilize further; conversely, a failure to break through the 1,815–1,820 point zone would continue to confirm the sideways, tug-of-war state.
Volatility risk in the midcap group remains present, while short-term opportunities are tilting toward stocks with tight price bases and positive trend signals. This remains a picture that requires further observation in the next session.
