As of the noon closing, the main indices of A-shares showed a pump trend, with the market volume significantly increasing by over 76 billion compared to the previous trading day. However, individual stock performance showed divergence, with the number of stocks falling greater than those rising.

The current market is facing the challenge of the 4000-point mark, which not only has psychological pressure but also actual trapped positions. It is expected that the index may consolidate horizontally near this level in the short term, in line with earlier market expectations.

Although the volume increased in the morning, it has not completely made up for yesterday's volume gap. From the current trading situation, the market volume still appears insufficient, making it difficult to support a sustained rise.

During the morning trading, sectors such as semiconductors and the sci-tech innovation board experienced a fall, resulting in an overall loss effect in the market. Only the rise in the brokerage sector provided some support to the market. However, due to the limited scale of the brokerage sector, it is difficult to drive a comprehensive rise in the market on its own.

Based on the current market pattern, afternoon trading is expected to mainly trend sideways with fluctuations. Investors should closely monitor changes in volume and individual stock performance, operate cautiously, and seize structural opportunities.
