The VN-Index tumbled towards the end of the session, slicing through the Bollinger Bands' Middle line. This movement reflects a resurgence of bearish sentiment as buying momentum remains subdued. Meanwhile, the Stochastic Oscillator has reissued a sell signal, while the MACD continues to weaken. The August 2025 low (around 1,600-1,630 points) is expected to provide support for the index should selling pressure intensify further.
