Market Preview Before the 18/08/2026 Session: VN-Index Holds Its Balance, Cash Flow Remains Selective
The market enters the 18/08 session moving sideways across the major indices. VN-Index closed at 1,727.5 points, while HNXINDEX stood at 278.6 points and UPCOMINDEX at 128.2 points, suggesting the overall backdrop still leans toward consolidation rather than a broad-based breakout.
Current technical data shows that individual stocks are displaying better signals than the broader market. Many tickers are maintaining an uptrend structure, with MACD still positive and RSI not yet entering overheated territory, while the overall index still needs further confirmation from liquidity.

Outlook for the Next Session
The nearest support zone for VN-Index remains around 1,720 points, while short-term resistance in the 1,730–1,735 point area remains the key level to watch. If liquidity does not improve, the index is likely to continue fluctuating within a narrow range, with divergence still favored.
Conversely, if active buying emerges at nearby resistance, the rebound could extend to stocks maintaining a positive MACD and a neutral RSI. Investors should continue monitoring the index's reaction in the 1,730–1,735 point zone along with the breadth of cash flow during the session.
