1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - Today, all stock indices oscillated and consolidated. The total trading volume of the stock market was 2732.1 billion yuan, a decrease of 324.3 billion yuan from the previous day. The macro - economy has strong resilience, but there are still some concerns on the demand side, and policy support is still needed in the future. Since the stock market rally mainly comes from the increase in the valuation side under loose liquidity, the expectation of performance recovery is not strong from the macro - economic indicators. Therefore, after this significant rebound, the stock indices need to oscillate and consolidate. With the policy signals of de - leveraging and risk control from the regulatory authorities, the optimistic sentiment in the stock market has cooled down, the trading volume has declined, and the stock indices have entered an oscillating and consolidating market. However, the positive policy expectations and the continuous net inflow of incremental funds into the stock market remain unchanged, and the main logic for the medium - and long - term upward trend of the stock indices remains unchanged. In general, it is expected that the stock indices will mainly oscillate and consolidate in the short term. For options, since the medium - and long - term upward logic of the stock indices is relatively solid, a bull spread strategy can be considered [4]. 3.
