Market developments before the May 13 session: sentiment remains positive
The May 13 session opened against a backdrop where the market continued to hold a positive tone after VNINDEX stayed above the 1,900.0-point level. From a short-term perspective, HNXINDEX is showing better momentum than the broader market, while UPCOMINDEX has corrected slightly and needs further confirmation from cash flow.
In terms of sentiment, the 1,900.0–1,905.0 point zone of VNINDEX remains an important support base. Conversely, the 1,910.0–1,920.0 point zone is seen as near-term resistance that could determine whether the uptrend can expand within the session.
| Index | Value | Change |
|---|---|---|
| VNINDEX | 1,901.1 | +5.6 points (+0.3%) |
| HNXINDEX | 253.3 | +2.1% |
| UPCOMINDEX | 126.6 | -0.5% |
Market overview: the 1,900-point price base holds
The fact that VNINDEX remains above 1,900.0 points suggests the primary trend has not yet been broken. This is a key factor helping the market maintain its balance, especially as buying pressure continues to appear in some stock groups with solid technical foundations.
On the other hand, UPCOMINDEX falling 0.5% indicates that the rally has not spread evenly. This reflects increasingly clear divergence among sectors and individual stocks.

Notable stock groups
Strong gainers on HOSE
| Ticker | Change |
|---|---|
| DXS | +6.9% |
| FDC | +6.9% |
| CDC | +6.9% |
Decliners on HOSE
| Ticker | Change |
|---|---|
| STG | -7.0% |
| GEE | -6.6% |
| HTV | -6.4% |
Liquidity is notably concentrated in several leading HOSE stocks, with SHB, VIX, and DXG continuing to rank among those with the largest trading volumes. This signals that cash flow still favors stocks with high recognition and strong ability to attract trading.
| Ticker | Volume |
|---|---|
| SHB | 45.0M |
| VIX | 38.0M |
| DXG | 33.8M |
Sector analysis and technical signals
The oil and gas, power, and some midcap groups are maintaining relatively positive technical structures. Among the notable technical signal list, PSI, POW, and PVI all have high composite scores, reflecting that the uptrend is still being sustained in these stocks.
| Ticker | Composite Score | EMA Trend | MACD Trend |
|---|---|---|---|
| PSI | 79.4 | uptrend | uptrend |
| POW | 78.2 | uptrend | uptrend |
| PVI | 77.4 | mixed | uptrend |
In a market showing divergence, stocks with high composite scores and consistent technical trends tend to remain the focus of short-term cash flow. Nevertheless, the rally still needs to be tested against nearby resistance zones and the response of liquidity.
HNX and UPCOM: cash flow remains selective
HNXINDEX reached 253.3 points, showing a more positive trend compared to the broader market. Among the standout stocks, TET and ALT both rose close to the ceiling price, while LMC and UPC led the upward momentum on UPCOM.
| Market | Index | Standout Stock | Change |
|---|---|---|---|
| HNX | 253.3 | TET | +10.0% |
| HNX | 253.3 | ALT | +9.8% |
| UPCOM | 126.6 | LMC | +14.9% |
| UPCOM | 126.6 | UPC | +14.9% |
Risks to Watch
- The securities sector may diverge due to negative news related to BMS.
- UPCOMINDEX is relatively weaker, indicating that the breadth of the rally has not been truly even.
- The 1,910.0–1,920.0 point zone of VNINDEX remains near-term resistance that still needs further testing.
Outlook for the Trading Session
The most likely scenario for the morning session is that the market fluctuates mildly around the opening level before testing supply and demand at nearby resistance levels. If buying demand continues to hold well in the blue-chip stocks and the midcap groups leading the way, VNINDEX still has room to extend its short-term uptrend.
Conversely, if profit-taking pressure emerges early in the 1,910.0–1,920.0 point zone, the market could enter a more intense tug-of-war phase with deeper divergence across sectors. In this context, focusing on stocks with solid technical foundations and stable liquidity would be a more cautious strategy.
