on the trading front, technology sectors led the rally. sectors such as electronic chemicals, pet copper foil, and semiconductors all strengthened, reflecting continued investor optimism toward the tech industry. conversely, sectors like hyperbaric oxygen chambers, genetically modified organisms, and baijiu underperformed and are currently undergoing adjustments.
the combined turnover for the shanghai and shenzhen markets reached rmb 1.7 trillion in the first half of the day. although this represents a slight contraction of rmb 28.7 billion compared with the previous trading session, market activity remained robust. hotspots rotated rapidly across the board, with nearly 2,800 individual stocks declining; nonetheless, the strong performance of tech stocks continued to attract substantial capital inflows.
