1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints - Today, all stock indices fluctuated and consolidated. The total market turnover was 30,547 billion yuan, an increase of 1,163 billion yuan compared to the previous day. The stock market turnover dropped to around 3 trillion, indicating a cooling of the optimistic sentiment in the stock market as the market absorbed the policy signals from the regulatory authorities to reduce leverage and control risks. Since the beginning of the year, the rise in the stock market has mainly come from the increase in the valuation side under the loose liquidity. From the perspective of macro - economic indicators, the expectation of performance recovery is not strong. The market divergence has led to intensified long - short games. Therefore, after this significant rebound, the stock indices need to fluctuate and consolidate, and the short - term volatility of the stock indices will intensify. In the medium - to - long - term, 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 - to - long - term upward movement of the stock indices remains unchanged. In general, it is expected that the stock indices will continue to fluctuate and consolidate in the short term. - For options, since the logic for the medium - to - long - term upward movement of the stock indices is relatively solid, a bull spread strategy can be considered [4]. 3.
