Market commentary 2026/10/16: Volatility on derivatives expiry day

The VNIndex extended its losing streak to seven consecutive sessions, while trading liquidity increased on the index futures expiry day. This indicated that selling pressure remained present, while buying demand was insufficient to support a market recovery. The prolonged decline and the lack of clear signs of easing correction pressure suggested that the short-term trend was weakening, with cautious sentiment continuing to prevail.
