Group 1: Investment Rating - No investment rating information is provided in the report. Group 2: Core Views - On December 1, 2025, the stock indices oscillated and rebounded. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1889.4 billion yuan, an increase of 291.7 billion yuan from the previous day. The manufacturing PMI in November was 49.2%, up 0.2 percentage points from the previous month but still below the boom - bust line, indicating insufficient effective domestic demand and strong expectations for policy support. The central economic work conference in December is expected to bring incremental policy benefits. Overseas, the expectation of the Fed's interest rate cut has increased, and the risk of AI asset investment bubble has cooled, reducing market risk - aversion sentiment. In general, the expectations of policy benefits and the trend of long - term capital inflows remain unchanged, providing strong support for the stock indices. It is expected that the stock indices will oscillate strongly in the short term [4]. - For options, considering the medium - to long - term upward trend of the stock indices, a bull spread or ratio spread strategy with a mild bullish view can be adopted [4].
