1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints - Today, the performance of each stock index was differentiated. CSI 500 and CSI 1000 performed strongly, while SSE 50 and SSE 300 performed weakly. The total trading volume of the stock market was 262.36 billion yuan, a decrease of 18.05 billion yuan from the previous day. With the policy signals of the regulatory authorities to reduce leverage and control risks, the optimistic sentiment in the stock market has cooled down, and the trading volume of the stock market has declined. The stock index has entered a volatile consolidation market. [4] - From the latest macroeconomic indicators, the macroeconomy has strong resilience, but the problem of weak domestic demand still exists. The expectation of macro - policy support for demand in the future is relatively clear. On the other hand, the policy side has a strong determination to support technological innovation and boost consumption. A series of subsequent policies will form a positive policy expectation for small - and medium - cap technology - growth stocks. [4] - In the short term, the inflow of margin trading funds has slowed down, and the driving effect of funds on the stock index has weakened. The upside and downside space of the stock index is limited in the short term. However, the positive policy expectation and the trend of continuous net inflow of incremental funds into the stock market remain unchanged. The main logic for the medium - and long - term upward movement of the stock index remains unchanged. In general, it is expected that the stock index will mainly consolidate in the short term. [4] - In terms of options, since the medium - and long - term upward logic of the stock index is relatively solid, it can be treated with a bull spread strategy. [4] 3.
