1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - Today, the stock indices showed mixed trends. The SSE 50 and CSI 300 closed up, while the CSI 500 and CSI 1000 closed down. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1948.7 billion yuan, a decrease of 141.7 billion yuan from the previous day. The latest financial data for September indicates that the financing demand of the household sector remains weak, and the problem of insufficient effective domestic demand persists. Coupled with the ongoing impact of external tariff factors, there are strong expectations for policy measures to stabilize the macro - fundamentals in the future, which will provide long - term support for the stock indices. However, in the short term, there are still uncertainties and risks before November, and the significant increase in stock valuations has led to an increase in investors' willingness to take profits, resulting in short - term technical adjustment pressure. Overall, the subsequent market trend depends on the interaction between profit - taking sentiment and policy - driven positive expectations, and the stock indices are expected to remain volatile in the short term. Currently, the implied volatility of options remains relatively stable. Considering the long - term upward trend of the stock indices, investors can continue to hold bull spreads or covered calls [4]. 3.
