Contrasting developments
During the morning session, the index briefly rose by more than 20 points thanks to support from some banking stocks and blue-chip stocks. However, red quickly prevailed, causing the VN-Index to narrow its gains and reverse course towards the end of the session.
In the afternoon session, selling pressure spread, with many large and small stocks falling simultaneously, causing the index to briefly drop below 1,625 points. Although supply slowed down at the support level, cautious sentiment prevented a strong increase in demand, and the VN-Index fluctuated until the close.
