On the morning of February 27, the A-share market witnessed a session characterized by erratic fluctuations. The benchmark Shanghai Composite Index slipped into negative territory, while the ChiNext Index, which tracks growth enterprises, tumbled by over 1%. A notable divergence emerged between the yellow line (representing the weighted average price of all stocks) and the white line (reflecting the price trend of large-cap stocks). Trading activity on the Shanghai and Shenzhen stock exchanges saw morning volumes reach 1.59 trillion yuan, marking a contraction of 53 billion yuan from the previous trading day. More than 2,900 stocks ended the morning session in the red.

Sector-wise, the computing power leasing concept emerged as a standout performer, bucking the broader market trend. Meanwhile, non-ferrous metals, AI programming, and space-based photovoltaic sectors exhibited resilience with active trading. In contrast, the electronic textile concept continued its downward trajectory, facing ongoing adjustments. By midday, the Shanghai Composite Index had retreated 0.17%, the Shenzhen Component Index had declined by 0.68%, and the ChiNext Index had suffered a steeper drop of 1.46%.
