On December 15, Chinese stock indices showed weak fluctuations during the morning session, with over 2,600 stocks advancing. The half-day turnover reached 1.2 trillion yuan, down 52.93 billion yuan from the previous day. By midday, the Shanghai Composite Index fell 0.11%, the Shenzhen Component Index dropped 0.71%, and the ChiNext Index declined 1.29%. Analysts attributed the market sentiment to several factors: a broad slump in cryptocurrency markets, with Bitcoin plunging over 2%, and risk-off sentiment triggered by Oracle's delayed OpenAI data center plans. Additionally, heightened expectations of a 25-basis-point rate hike by the Bank of Japan at its upcoming meeting further weighed on investor caution.
